Chapter 3. Installing a cluster on Nutanix in a restricted network
Chapter 3. Installing a cluster on Nutanix in a restricted network In OpenShift Container Platform 4.12, you can install a cluster on Nutanix infrastructure in a restricted network by creating an internal mirror of the installation release content. 3.1. Prerequisites You have reviewed details about the OpenShift Container Platform installation and update processes. The installation program requires access to port 9440 on Prism Central and Prism Element. You verified that port 9440 is accessible. If you use a firewall, you have met these prerequisites: You confirmed that port 9440 is accessible. Control plane nodes must be able to reach Prism Central and Prism Element on port 9440 for the installation to succeed. You configured the firewall to grant access to the sites that OpenShift Container Platform requires. This includes the use of Telemetry. If your Nutanix environment is using the default self-signed SSL/TLS certificate, replace it with a certificate that is signed by a CA. The installation program requires a valid CA-signed certificate to access to the Prism Central API. For more information about replacing the self-signed certificate, see the Nutanix AOS Security Guide . If your Nutanix environment uses an internal CA to issue certificates, you must configure a cluster-wide proxy as part of the installation process. For more information, see Configuring a custom PKI . Important Use 2048-bit certificates. The installation fails if you use 4096-bit certificates with Prism Central 2022.x. You have a container image registry, such as Red Hat Quay. If you do not already have a registry, you can create a mirror registry using mirror registry for Red Hat OpenShift . You have used the oc-mirror OpenShift CLI (oc) plugin to mirror all of the required OpenShift Container Platform content and other images, including the Nutanix CSI Operator, to your mirror registry. Important Because the installation media is on the mirror host, you can use that computer to complete all installation steps. 3.2. About installations in restricted networks In OpenShift Container Platform 4.12, you can perform an installation that does not require an active connection to the internet to obtain software components. Restricted network installations can be completed using installer-provisioned infrastructure or user-provisioned infrastructure, depending on the cloud platform to which you are installing the cluster. If you choose to perform a restricted network installation on a cloud platform, you still require access to its cloud APIs. Some cloud functions, like Amazon Web Service's Route 53 DNS and IAM services, require internet access. Depending on your network, you might require less internet access for an installation on bare metal hardware, Nutanix, or on VMware vSphere. To complete a restricted network installation, you must create a registry that mirrors the contents of the OpenShift image registry and contains the installation media. You can create this registry on a mirror host, which can access both the internet and your closed network, or by using other methods that meet your restrictions. 3.2.1. Additional limits Clusters in restricted networks have the following additional limitations and restrictions: The ClusterVersion status includes an Unable to retrieve available updates error. By default, you cannot use the contents of the Developer Catalog because you cannot access the required image stream tags. 3.3. Generating a key pair for cluster node SSH access During an OpenShift Container Platform installation, you can provide an SSH public key to the installation program. The key is passed to the Red Hat Enterprise Linux CoreOS (RHCOS) nodes through their Ignition config files and is used to authenticate SSH access to the nodes. The key is added to the ~/.ssh/authorized_keys list for the core user on each node, which enables password-less authentication. After the key is passed to the nodes, you can use the key pair to SSH in to the RHCOS nodes as the user core . To access the nodes through SSH, the private key identity must be managed by SSH for your local user. If you want to SSH in to your cluster nodes to perform installation debugging or disaster recovery, you must provide the SSH public key during the installation process. The ./openshift-install gather command also requires the SSH public key to be in place on the cluster nodes. Important Do not skip this procedure in production environments, where disaster recovery and debugging is required. Note You must use a local key, not one that you configured with platform-specific approaches such as AWS key pairs . Procedure If you do not have an existing SSH key pair on your local machine to use for authentication onto your cluster nodes, create one. For example, on a computer that uses a Linux operating system, run the following command: USD ssh-keygen -t ed25519 -N '' -f <path>/<file_name> 1 1 Specify the path and file name, such as ~/.ssh/id_ed25519 , of the new SSH key. If you have an existing key pair, ensure your public key is in the your ~/.ssh directory. Note If you plan to install an OpenShift Container Platform cluster that uses FIPS validated or Modules In Process cryptographic libraries on the x86_64 , ppc64le , and s390x architectures. do not create a key that uses the ed25519 algorithm. Instead, create a key that uses the rsa or ecdsa algorithm. View the public SSH key: USD cat <path>/<file_name>.pub For example, run the following to view the ~/.ssh/id_ed25519.pub public key: USD cat ~/.ssh/id_ed25519.pub Add the SSH private key identity to the SSH agent for your local user, if it has not already been added. SSH agent management of the key is required for password-less SSH authentication onto your cluster nodes, or if you want to use the ./openshift-install gather command. Note On some distributions, default SSH private key identities such as ~/.ssh/id_rsa and ~/.ssh/id_dsa are managed automatically. If the ssh-agent process is not already running for your local user, start it as a background task: USD eval "USD(ssh-agent -s)" Example output Agent pid 31874 Note If your cluster is in FIPS mode, only use FIPS-compliant algorithms to generate the SSH key. The key must be either RSA or ECDSA. Add your SSH private key to the ssh-agent : USD ssh-add <path>/<file_name> 1 1 Specify the path and file name for your SSH private key, such as ~/.ssh/id_ed25519 Example output Identity added: /home/<you>/<path>/<file_name> (<computer_name>) steps When you install OpenShift Container Platform, provide the SSH public key to the installation program. 3.4. Adding Nutanix root CA certificates to your system trust Because the installation program requires access to the Prism Central API, you must add your Nutanix trusted root CA certificates to your system trust before you install an OpenShift Container Platform cluster. Procedure From the Prism Central web console, download the Nutanix root CA certificates. Extract the compressed file that contains the Nutanix root CA certificates. Add the files for your operating system to the system trust. For example, on a Fedora operating system, run the following command: # cp certs/lin/* /etc/pki/ca-trust/source/anchors Update your system trust. For example, on a Fedora operating system, run the following command: # update-ca-trust extract 3.5. Downloading the RHCOS cluster image Prism Central requires access to the Red Hat Enterprise Linux CoreOS (RHCOS) image to install the cluster. You can use the installation program to locate and download the RHCOS image and make it available through an internal HTTP server or Nutanix Objects. Prerequisites Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your mirror host. Procedure Change to the directory that contains the installation program and run the following command: USD ./openshift-install coreos print-stream-json Use the output of the command to find the location of the Nutanix image, and click the link to download it. Example output "nutanix": { "release": "411.86.202210041459-0", "formats": { "qcow2": { "disk": { "location": "https://rhcos.mirror.openshift.com/art/storage/releases/rhcos-4.11/411.86.202210041459-0/x86_64/rhcos-411.86.202210041459-0-nutanix.x86_64.qcow2", "sha256": "42e227cac6f11ac37ee8a2f9528bb3665146566890577fd55f9b950949e5a54b" Make the image available through an internal HTTP server or Nutanix Objects. Note the location of the downloaded image. You update the platform section in the installation configuration file ( install-config.yaml ) with the image's location before deploying the cluster. Snippet of an install-config.yaml file that specifies the RHCOS image platform: nutanix: clusterOSImage: http://example.com/images/rhcos-411.86.202210041459-0-nutanix.x86_64.qcow2 3.6. Creating the installation configuration file You can customize the OpenShift Container Platform cluster you install on Nutanix. Prerequisites Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. For a restricted network installation, these files are on your mirror host. Have the imageContentSourcePolicy.yaml file that was created when you mirrored your registry. Have the location of the Red Hat Enterprise Linux CoreOS (RHCOS) image you download. Obtain the contents of the certificate for your mirror registry. Retrieve a Red Hat Enterprise Linux CoreOS (RHCOS) image and upload it to an accessible location. Verify that you have met the Nutanix networking requirements. For more information, see "Preparing to install on Nutanix". Procedure Create the install-config.yaml file. Change to the directory that contains the installation program and run the following command: USD ./openshift-install create install-config --dir <installation_directory> 1 1 For <installation_directory> , specify the directory name to store the files that the installation program creates. When specifying the directory: Verify that the directory has the execute permission. This permission is required to run Terraform binaries under the installation directory. Use an empty directory. Some installation assets, such as bootstrap X.509 certificates, have short expiration intervals, therefore you must not reuse an installation directory. If you want to reuse individual files from another cluster installation, you can copy them into your directory. However, the file names for the installation assets might change between releases. Use caution when copying installation files from an earlier OpenShift Container Platform version. At the prompts, provide the configuration details for your cloud: Optional: Select an SSH key to use to access your cluster machines. Note For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses. Select nutanix as the platform to target. Enter the Prism Central domain name or IP address. Enter the port that is used to log into Prism Central. Enter the credentials that are used to log into Prism Central. The installation program connects to Prism Central. Select the Prism Element that will manage the OpenShift Container Platform cluster. Select the network subnet to use. Enter the virtual IP address that you configured for control plane API access. Enter the virtual IP address that you configured for cluster ingress. Enter the base domain. This base domain must be the same one that you configured in the DNS records. Enter a descriptive name for your cluster. The cluster name you enter must match the cluster name you specified when configuring the DNS records. Paste the pull secret from the Red Hat OpenShift Cluster Manager . In the install-config.yaml file, set the value of platform.nutanix.clusterOSImage to the image location or name. For example: platform: nutanix: clusterOSImage: http://mirror.example.com/images/rhcos-47.83.202103221318-0-nutanix.x86_64.qcow2 Edit the install-config.yaml file to give the additional information that is required for an installation in a restricted network. Update the pullSecret value to contain the authentication information for your registry: pullSecret: '{"auths":{"<mirror_host_name>:5000": {"auth": "<credentials>","email": "you@example.com"}}}' For <mirror_host_name> , specify the registry domain name that you specified in the certificate for your mirror registry, and for <credentials> , specify the base64-encoded user name and password for your mirror registry. Add the additionalTrustBundle parameter and value. additionalTrustBundle: | -----BEGIN CERTIFICATE----- ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ -----END CERTIFICATE----- The value must be the contents of the certificate file that you used for your mirror registry. The certificate file can be an existing, trusted certificate authority, or the self-signed certificate that you generated for the mirror registry. Add the image content resources, which resemble the following YAML excerpt: imageContentSources: - mirrors: - <mirror_host_name>:5000/<repo_name>/release source: quay.io/openshift-release-dev/ocp-release - mirrors: - <mirror_host_name>:5000/<repo_name>/release source: registry.redhat.io/ocp/release For these values, use the imageContentSourcePolicy.yaml file that was created when you mirrored the registry. Optional: Update one or more of the default configuration parameters in the install.config.yaml file to customize the installation. For more information about the parameters, see "Installation configuration parameters". Back up the install-config.yaml file so that you can use it to install multiple clusters. Important The install-config.yaml file is consumed during the installation process. If you want to reuse the file, you must back it up now. 3.6.1. Installation configuration parameters Before you deploy an OpenShift Container Platform cluster, you provide parameter values to describe your account on the cloud platform that hosts your cluster and optionally customize your cluster's platform. When you create the install-config.yaml installation configuration file, you provide values for the required parameters through the command line. If you customize your cluster, you can modify the install-config.yaml file to provide more details about the platform. Note After installation, you cannot modify these parameters in the install-config.yaml file. 3.6.1.1. Required configuration parameters Required installation configuration parameters are described in the following table: Table 3.1. Required parameters Parameter Description Values apiVersion The API version for the install-config.yaml content. The current version is v1 . The installation program may also support older API versions. String baseDomain The base domain of your cloud provider. The base domain is used to create routes to your OpenShift Container Platform cluster components.

Network configuration parameters You can customize your installation configuration based on the requirements of your existing network infrastructure. For example, you can expand the IP address block for the cluster network or provide different IP address blocks than the defaults. Only IPv4 addresses are supported. Note Globalnet is not supported with Red Hat OpenShift Data Foundation disaster recovery solutions. For regional disaster recovery scenarios, ensure that you use a nonoverlapping range of private IP addresses for the cluster and service networks in each cluster. Table 3.2. Network parameters Parameter Description Values networking The configuration for the cluster network. Object Note You cannot modify parameters specified by the networking object after installation. networking.networkType The Red Hat OpenShift Networking network plugin to install.

If Prism Central does not have internet access, you can override the default behavior by hosting the RHCOS image on any HTTP server and pointing the installation program to the image. An HTTP or HTTPS URL, optionally with a SHA-256 checksum. For example, http://example.com/images/rhcos-47.83.202103221318-0-nutanix.x86_64.qcow2 The prismElements section holds a list of Prism Elements (clusters). A Prism Element encompasses all of the Nutanix resources, for example virtual machines and subnets, that are used to host the OpenShift Container Platform cluster. Only a single Prism Element is supported. Only one subnet per OpenShift Container Platform cluster is supported. 3.6.2. Sample customized install-config.yaml file for Nutanix You can customize the install-config.yaml file to specify more details about your OpenShift Container Platform cluster's platform or modify the values of the required parameters. Important This sample YAML file is provided for reference only. You must obtain your install-config.yaml file by using the installation program and modify it. apiVersion: v1 baseDomain: example.com 1 compute: 2 - hyperthreading: Enabled 3 name: worker replicas: 3 platform: nutanix: 4 cpus: 2 coresPerSocket: 2 memoryMiB: 8196 osDisk: diskSizeGiB: 120 controlPlane: 5 hyperthreading: Enabled 6 name: master replicas: 3 platform: nutanix: 7 cpus: 4 coresPerSocket: 2 memoryMiB: 16384 osDisk: diskSizeGiB: 120 metadata: creationTimestamp: null name: test-cluster 8 networking: clusterNetwork: - cidr: 10.128.0.0/14 hostPrefix: 23 machineNetwork: - cidr: 10.0.0.0/16 networkType: OVNKubernetes 9 serviceNetwork: - 172.30.0.0/16 platform: nutanix: apiVIP: 10.40.142.7 10 ingressVIP: 10.40.142.8 11 prismCentral: endpoint: address: your.prismcentral.domainname 12 port: 9440 13 password: <password> 14 username: <username> 15 prismElements: - endpoint: address: your.prismelement.domainname port: 9440 uuid: 0005b0f1-8f43-a0f2-02b7-3cecef193712 subnetUUIDs: - c7938dc6-7659-453e-a688-e26020c68e43 clusterOSImage: http://example.com/images/rhcos-47.83.202103221318-0-nutanix.x86_64.qcow2 16 credentialsMode: Manual publish: External pullSecret: '{"auths":{"<local_registry>": {"auth": "<credentials>","email": "you@example.com"}}}' 17 fips: false 18 sshKey: ssh-ed25519 AAAA... 19 additionalTrustBundle: | 20 -----BEGIN CERTIFICATE----- ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ -----END CERTIFICATE----- imageContentSources: 21 - mirrors: - <local_registry>/<local_repository_name>/release source: quay.io/openshift-release-dev/ocp-release - mirrors: - <local_registry>/<local_repository_name>/release source: quay.io/openshift-release-dev/ocp-v4.0-art-dev 1 8 10 11 12 13 14 15 Required. The installation program prompts you for this value. 2 5 The controlPlane section is a single mapping, but the compute section is a sequence of mappings. To meet the requirements of the different data structures, the first line of the compute section must begin with a hyphen, - , and the first line of the controlPlane section must not. Although both sections currently define a single machine pool, it is possible that future versions of OpenShift Container Platform will support defining multiple compute pools during installation. Only one control plane pool is used. 3 6 Whether to enable or disable simultaneous multithreading, or hyperthreading . By default, simultaneous multithreading is enabled to increase the performance of your machines' cores. You can disable it by setting the parameter value to Disabled . If you disable simultaneous multithreading in some cluster machines, you must disable it in all cluster machines. Important If you disable simultaneous multithreading, ensure that your capacity planning accounts for the dramatically decreased machine performance. 4 7 Optional: Provide additional configuration for the machine pool parameters for the compute and control plane machines. 9 The cluster network plugin to install. The supported values are OVNKubernetes and OpenShiftSDN . The default value is OVNKubernetes . 16 Optional: By default, the installation program downloads and installs the Red Hat Enterprise Linux CoreOS (RHCOS) image. If Prism Central does not have internet access, you can override the default behavior by hosting the RHCOS image on any HTTP server or Nutanix Objects and pointing the installation program to the image. 17 For <local_registry> , specify the registry domain name, and optionally the port, that your mirror registry uses to serve content. For example registry.example.com or registry.example.com:5000 . For <credentials> , specify the base64-encoded user name and password for your mirror registry. 18 Whether to enable or disable FIPS mode. By default, FIPS mode is not enabled. If FIPS mode is enabled, the Red Hat Enterprise Linux CoreOS (RHCOS) machines that OpenShift Container Platform runs on bypass the default Kubernetes cryptography suite and use the cryptography modules that are provided with RHCOS instead. Important The use of FIPS Validated or Modules in Process cryptographic libraries is only supported on OpenShift Container Platform deployments on the x86_64 , ppc64le , and s390x architectures. 19 Optional: You can provide the sshKey value that you use to access the machines in your cluster. Note For production OpenShift Container Platform clusters on which you want to perform installation debugging or disaster recovery, specify an SSH key that your ssh-agent process uses. 20 Provide the contents of the certificate file that you used for your mirror registry. 21 Provide these values from the metadata.name: release-0 section of the imageContentSourcePolicy.yaml file that was created when you mirrored the registry. 3.6.3. Configuring the cluster-wide proxy during installation Production environments can deny direct access to the internet and instead have an HTTP or HTTPS proxy available. You can configure a new OpenShift Container Platform cluster to use a proxy by configuring the proxy settings in the install-config.yaml file. Prerequisites You have an existing install-config.yaml file. You reviewed the sites that your cluster requires access to and determined whether any of them need to bypass the proxy. By default, all cluster egress traffic is proxied, including calls to hosting cloud provider APIs. You added sites to the Proxy object's spec.noProxy field to bypass the proxy if necessary. Note The Proxy object status.noProxy field is populated with the values of the networking.machineNetwork[].cidr , networking.clusterNetwork[].cidr , and networking.serviceNetwork[] fields from your installation configuration. For installations on Amazon Web Services (AWS), Google Cloud Platform (GCP), Microsoft Azure, and Red Hat OpenStack Platform (RHOSP), the Proxy object status.noProxy field is also populated with the instance metadata endpoint ( 169.254.169.254 ). Procedure Edit your install-config.yaml file and add the proxy settings. For example: apiVersion: v1 baseDomain: my.domain.com proxy: httpProxy: http://<username>:<pswd>@<ip>:<port> 1 httpsProxy: https://<username>:<pswd>@<ip>:<port> 2 noProxy: example.com 3 additionalTrustBundle: | 4 -----BEGIN CERTIFICATE----- <MY_TRUSTED_CA_CERT> -----END CERTIFICATE----- additionalTrustBundlePolicy: <policy_to_add_additionalTrustBundle> 5 1 A proxy URL to use for creating HTTP connections outside the cluster. The URL scheme must be http . 2 A proxy URL to use for creating HTTPS connections outside the cluster. 3 A comma-separated list of destination domain names, IP addresses, or other network CIDRs to exclude from proxying. Preface a domain with . to match subdomains only. For example, .y.com matches x.y.com , but not y.com . Use * to bypass the proxy for all destinations. 4 If provided, the installation program generates a config map that is named user-ca-bundle in the openshift-config namespace that contains one or more additional CA certificates that are required for proxying HTTPS connections. The Cluster Network Operator then creates a trusted-ca-bundle config map that merges these contents with the Red Hat Enterprise Linux CoreOS (RHCOS) trust bundle, and this config map is referenced in the trustedCA field of the Proxy object. The additionalTrustBundle field is required unless the proxy's identity certificate is signed by an authority from the RHCOS trust bundle. 5 Optional: The policy to determine the configuration of the Proxy object to reference the user-ca-bundle config map in the trustedCA field. The allowed values are Proxyonly and Always . Use Proxyonly to reference the user-ca-bundle config map only when http/https proxy is configured. Use Always to always reference the user-ca-bundle config map. The default value is Proxyonly . Note The installation program does not support the proxy readinessEndpoints field. Note If the installer times out, restart and then complete the deployment by using the wait-for command of the installer. For example: USD ./openshift-install wait-for install-complete --log-level debug Save the file and reference it when installing OpenShift Container Platform. The installation program creates a cluster-wide proxy that is named cluster that uses the proxy settings in the provided install-config.yaml file. If no proxy settings are provided, a cluster Proxy object is still created, but it will have a nil spec . Note Only the Proxy object named cluster is supported, and no additional proxies can be created. 3.7. Installing the OpenShift CLI by downloading the binary You can install the OpenShift CLI ( oc ) to interact with OpenShift Container Platform from a command-line interface. You can install oc on Linux, Windows, or macOS. Important If you installed an earlier version of oc , you cannot use it to complete all of the commands in OpenShift Container Platform 4.12.

Configuring IAM for Nutanix Installing the cluster requires that the Cloud Credential Operator (CCO) operate in manual mode. While the installation program configures the CCO for manual mode, you must specify the identity and access management secrets. Prerequisites You have configured the ccoctl binary. You have an install-config.yaml file. Procedure Create a YAML file that contains the credentials data in the following format: Credentials data format credentials: - type: basic_auth 1 data: prismCentral: 2 username: <username_for_prism_central> password: <password_for_prism_central> prismElements: 3 - name: <name_of_prism_element> username: <username_for_prism_element> password: <password_for_prism_element> 1 Specify the authentication type. Only basic authentication is supported. 2 Specify the Prism Central credentials. 3 Optional: Specify the Prism Element credentials. Set a USDRELEASE_IMAGE variable with the release image from your installation file by running the following command: USD RELEASE_IMAGE=USD(./openshift-install version | awk '/release image/ {print USD3}') Extract the list of CredentialsRequest custom resources (CRs) from the OpenShift Container Platform release image by running the following command: USD oc adm release extract \ --from=USDRELEASE_IMAGE \ --credentials-requests \ --cloud=nutanix \ --to=<path_to_directory_with_list_of_credentials_requests>/credrequests 1 1 Specify the path to the directory that contains the files for the component CredentialsRequests objects. If the specified directory does not exist, this command creates it. Sample CredentialsRequest object apiVersion: cloudcredential.openshift.io/v1 kind: CredentialsRequest metadata: annotations: include.release.openshift.io/self-managed-high-availability: "true" labels: controller-tools.k8s.io: "1.0" name: openshift-machine-api-nutanix namespace: openshift-cloud-credential-operator spec: providerSpec: apiVersion: cloudcredential.openshift.io/v1 kind: NutanixProviderSpec secretRef: name: nutanix-credentials namespace: openshift-machine-api If your cluster uses cluster capabilities to disable one or more optional components, delete the CredentialsRequest custom resources for any disabled components. Example credrequests directory contents for OpenShift Container Platform 4.12 on Nutanix 0000_30_machine-api-operator_00_credentials-request.yaml 1 1 The Machine API Operator CR is required. Use the ccoctl tool to process all of the CredentialsRequest objects in the credrequests directory by running the following command: USD ccoctl nutanix create-shared-secrets \ --credentials-requests-dir=<path_to_directory_with_list_of_credentials_requests>/credrequests \ 1 --output-dir=<ccoctl_output_dir> \ 2 --credentials-source-filepath=<path_to_credentials_file> 3 1 Specify the path to the directory that contains the files for the component CredentialsRequests objects. 2 Specify the directory that contains the files of the component credentials secrets, under the manifests directory. By default, the ccoctl tool creates objects in the directory in which the commands are run. To create the objects in a different directory, use the --output-dir flag. 3 Optional: Specify the directory that contains the credentials data YAML file. By default, ccoctl expects this file to be in <home_directory>/.nutanix/credentials . To specify a different directory, use the --credentials-source-filepath flag. Edit the install-config.yaml configuration file so that the credentialsMode parameter is set to Manual . Example install-config.yaml configuration file apiVersion: v1 baseDomain: cluster1.example.com credentialsMode: Manual 1 ... 1 Add this line to set the credentialsMode parameter to Manual . Create the installation manifests by running the following command: USD openshift-install create manifests --dir <installation_directory> 1 1 Specify the path to the directory that contains the install-config.yaml file for your cluster. Copy the generated credential files to the target manifests directory by running the following command: USD cp <ccoctl_output_dir>/manifests/*credentials.yaml ./<installation_directory>/manifests Verification Ensure that the appropriate secrets exist in the manifests directory. USD ls ./<installation_directory>/manifests Example output total 64 -rw-r----- 1 <user> <user> 2335 Jul 8 12:22 cluster-config.yaml -rw-r----- 1 <user> <user> 161 Jul 8 12:22 cluster-dns-02-config.yml -rw-r----- 1 <user> <user> 864 Jul 8 12:22 cluster-infrastructure-02-config.yml -rw-r----- 1 <user> <user> 191 Jul 8 12:22 cluster-ingress-02-config.yml -rw-r----- 1 <user> <user> 9607 Jul 8 12:22 cluster-network-01-crd.yml -rw-r----- 1 <user> <user> 272 Jul 8 12:22 cluster-network-02-config.yml -rw-r----- 1 <user> <user> 142 Jul 8 12:22 cluster-proxy-01-config.yaml -rw-r----- 1 <user> <user> 171 Jul 8 12:22 cluster-scheduler-02-config.yml -rw-r----- 1 <user> <user> 200 Jul 8 12:22 cvo-overrides.yaml -rw-r----- 1 <user> <user> 118 Jul 8 12:22 kube-cloud-config.yaml -rw-r----- 1 <user> <user> 1304 Jul 8 12:22 kube-system-configmap-root-ca.yaml -rw-r----- 1 <user> <user> 4090 Jul 8 12:22 machine-config-server-tls-secret.yaml -rw-r----- 1 <user> <user> 3961 Jul 8 12:22 openshift-config-secret-pull-secret.yaml -rw------- 1 <user> <user> 283 Jul 8 12:24 openshift-machine-api-nutanix-credentials-credentials.yaml 3.9. Deploying the cluster You can install OpenShift Container Platform on a compatible cloud platform. Important You can run the create cluster command of the installation program only once, during initial installation. Prerequisites Obtain the OpenShift Container Platform installation program and the pull secret for your cluster. Verify the cloud provider account on your host has the correct permissions to deploy the cluster. An account with incorrect permissions causes the installation process to fail with an error message that displays the missing permissions. Procedure Change to the directory that contains the installation program and initialize the cluster deployment: USD ./openshift-install create cluster --dir <installation_directory> \ 1 --log-level=info 2 1 For <installation_directory> , specify the location of your customized ./install-config.yaml file. 2 To view different installation details, specify warn , debug , or error instead of info . Note If the cloud provider account that you configured on your host does not have sufficient permissions to deploy the cluster, the installation process stops, and the missing permissions are displayed. Verification When the cluster deployment completes successfully: The terminal displays directions for accessing your cluster, including a link to the web console and credentials for the kubeadmin user. Credential information also outputs to <installation_directory>/.openshift_install.log . Important Do not delete the installation program or the files that the installation program creates. Both are required to delete the cluster. Example output ... INFO Install complete! INFO To access the cluster as the system:admin user when using 'oc', run 'export KUBECONFIG=/home/myuser/install_dir/auth/kubeconfig' INFO Access the OpenShift web-console here: https://console-openshift-console.apps.mycluster.example.com INFO Login to the console with user: "kubeadmin", and password: "password" INFO Time elapsed: 36m22s Important The Ignition config files that the installation program generates contain certificates that expire after 24 hours, which are then renewed at that time. If the cluster is shut down before renewing the certificates and the cluster is later restarted after the 24 hours have elapsed, the cluster automatically recovers the expired certificates. The exception is that you must manually approve the pending node-bootstrapper certificate signing requests (CSRs) to recover kubelet certificates. See the documentation for Recovering from expired control plane certificates for more information. It is recommended that you use Ignition config files within 12 hours after they are generated because the 24-hour certificate rotates from 16 to 22 hours after the cluster is installed. By using the Ignition config files within 12 hours, you can avoid installation failure if the certificate update runs during installation. 3.10. Post installation Complete the following steps to complete the configuration of your cluster. 3.10.1. Disabling the default OperatorHub catalog sources Operator catalogs that source content provided by Red Hat and community projects are configured for OperatorHub by default during an OpenShift Container Platform installation. In a restricted network environment, you must disable the default catalogs as a cluster administrator. Procedure Disable the sources for the default catalogs by adding disableAllDefaultSources: true to the OperatorHub object: USD oc patch OperatorHub cluster --type json \ -p '[{"op": "add", "path": "/spec/disableAllDefaultSources", "value": true}]' Tip Alternatively, you can use the web console to manage catalog sources. From the Administration Cluster Settings Configuration OperatorHub page, click the Sources tab, where you can create, update, delete, disable, and enable individual sources. 3.10.2. Installing the policy resources into the cluster Mirroring the OpenShift Container Platform content using the oc-mirror OpenShift CLI (oc) plugin creates resources, which include catalogSource-certified-operator-index.yaml and imageContentSourcePolicy.yaml . The ImageContentSourcePolicy resource associates the mirror registry with the source registry and redirects image pull requests from the online registries to the mirror registry. The CatalogSource resource is used by Operator Lifecycle Manager (OLM) to retrieve information about the available Operators in the mirror registry, which lets users discover and install Operators. After you install the cluster, you must install these resources into the cluster. Prerequisites You have mirrored the image set to the registry mirror in the disconnected environment. You have access to the cluster as a user with the cluster-admin role. Procedure Log in to the OpenShift CLI as a user with the cluster-admin role. Apply the YAML files from the results directory to the cluster: USD oc apply -f ./oc-mirror-workspace/results-<id>/ Verification Verify that the ImageContentSourcePolicy resources were successfully installed: USD oc get imagecontentsourcepolicy Verify that the CatalogSource resources were successfully installed: USD oc get catalogsource --all-namespaces 3.10.3. Configuring the default storage container After you install the cluster, you must install the Nutanix CSI Operator and configure the default storage container for the cluster. For more information, see the Nutanix documentation for installing the CSI Operator and configuring registry storage . 3.11. Telemetry access for OpenShift Container Platform In OpenShift Container Platform 4.12, the Telemetry service, which runs by default to provide metrics about cluster health and the success of updates, requires internet access. If your cluster is connected to the internet, Telemetry runs automatically, and your cluster is registered to OpenShift Cluster Manager Hybrid Cloud Console . After you confirm that your OpenShift Cluster Manager Hybrid Cloud Console inventory is correct, either maintained automatically by Telemetry or manually by using OpenShift Cluster Manager, use subscription watch to track your OpenShift Container Platform subscriptions at the account or multi-cluster level. 3.12. Additional resources About remote health monitoring 3.13. steps If necessary, see Opt out of remote health reporting If necessary, see Registering your disconnected cluster Customize your cluster
