Chapter 22. Network [operator.openshift.io/v1]
Chapter 22. Network [operator.openshift.io/v1] Description Network describes the cluster's desired network configuration. It is consumed by the cluster-network-operator. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object 22.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object NetworkSpec is the top-level network configuration object. status object NetworkStatus is detailed operator status, which is distilled up to the Network clusteroperator object. 22.1.1. .spec Description NetworkSpec is the top-level network configuration object. Type object Property Type Description additionalNetworks array additionalNetworks is a list of extra networks to make available to pods when multiple networks are enabled. additionalNetworks[] object AdditionalNetworkDefinition configures an extra network that is available but not created by default. Instead, pods must request them by name. type must be specified, along with exactly one "Config" that matches the type. clusterNetwork array clusterNetwork is the IP address pool to use for pod IPs. Some network providers, e.g. OpenShift SDN, support multiple ClusterNetworks. Others only support one. This is equivalent to the cluster-cidr. clusterNetwork[] object ClusterNetworkEntry is a subnet from which to allocate PodIPs. A network of size HostPrefix (in CIDR notation) will be allocated when nodes join the cluster. If the HostPrefix field is not used by the plugin, it can be left unset. Not all network providers support multiple ClusterNetworks defaultNetwork object defaultNetwork is the "default" network that all pods will receive deployKubeProxy boolean deployKubeProxy specifies whether or not a standalone kube-proxy should be deployed by the operator. Some network providers include kube-proxy or similar functionality. If unset, the plugin will attempt to select the correct value, which is false when OpenShift SDN and ovn-kubernetes are used and true otherwise. disableMultiNetwork boolean disableMultiNetwork specifies whether or not multiple pod network support should be disabled. If unset, this property defaults to 'false' and multiple network support is enabled. disableNetworkDiagnostics boolean disableNetworkDiagnostics specifies whether or not PodNetworkConnectivityCheck CRs from a test pod to every node, apiserver and LB should be disabled or not. If unset, this property defaults to 'false' and network diagnostics is enabled. Setting this to 'true' would reduce the additional load of the pods performing the checks. exportNetworkFlows object exportNetworkFlows enables and configures the export of network flow metadata from the pod network by using protocols NetFlow, SFlow or IPFIX. Currently only supported on OVN-Kubernetes plugin. If unset, flows will not be exported to any collector. kubeProxyConfig object kubeProxyConfig lets us configure desired proxy configuration. If not specified, sensible defaults will be chosen by OpenShift directly. Not consumed by all network providers - currently only openshift-sdn. logLevel string logLevel is an intent based logging for an overall component. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for their operands. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal". managementState string managementState indicates whether and how the operator should manage the component migration object migration enables and configures the cluster network migration. The migration procedure allows to change the network type and the MTU. observedConfig `` observedConfig holds a sparse config that controller has observed from the cluster state. It exists in spec because it is an input to the level for the operator operatorLogLevel string operatorLogLevel is an intent based logging for the operator itself. It does not give fine grained control, but it is a simple way to manage coarse grained logging choices that operators have to interpret for themselves. Valid values are: "Normal", "Debug", "Trace", "TraceAll". Defaults to "Normal". serviceNetwork array (string) serviceNetwork is the ip address pool to use for Service IPs Currently, all existing network providers only support a single value here, but this is an array to allow for growth. unsupportedConfigOverrides `` unsupportedConfigOverrides overrides the final configuration that was computed by the operator. Red Hat does not support the use of this field. Misuse of this field could lead to unexpected behavior or conflict with other configuration options. Seek guidance from the Red Hat support before using this field. Use of this property blocks cluster upgrades, it must be removed before upgrading your cluster. useMultiNetworkPolicy boolean useMultiNetworkPolicy enables a controller which allows for MultiNetworkPolicy objects to be used on additional networks as created by Multus CNI. MultiNetworkPolicy are similar to NetworkPolicy objects, but NetworkPolicy objects only apply to the primary interface. With MultiNetworkPolicy, you can control the traffic that a pod can receive over the secondary interfaces. If unset, this property defaults to 'false' and MultiNetworkPolicy objects are ignored. If 'disableMultiNetwork' is 'true' then the value of this field is ignored. 22.1.2. .spec.additionalNetworks Description additionalNetworks is a list of extra networks to make available to pods when multiple networks are enabled. Type array 22.1.3. .spec.additionalNetworks[] Description AdditionalNetworkDefinition configures an extra network that is available but not created by default.

Type object Property Type Description reachabilityTotalTimeoutSeconds integer reachabilityTotalTimeout configures the EgressIP node reachability check total timeout in seconds. If the EgressIP node cannot be reached within this timeout, the node is declared down. Setting a large value may cause the EgressIP feature to react slowly to node changes.

When omitted, this means the user has no opinion and the platform is left to choose a reasonable default, which is subject to change over time. The current default is 1 second. A value of 0 disables the EgressIP node's reachability check. 22.1.18. .spec.defaultNetwork.ovnKubernetesConfig.gatewayConfig Description gatewayConfig holds the configuration for node gateway options.

Check individual members fields within ipv6 for details of default values. routingViaHost boolean RoutingViaHost allows pod egress traffic to exit via the ovn-k8s-mp0 management port into the host before sending it out. If this is not set, traffic will always egress directly from OVN to outside without touching the host stack. Setting this to true means hardware offload will not be supported.

When 'Full', ipsec is configured on the node level and inter-pod secure communication within the cluster is configured. Note with Full , if ipsec is desired for communication with external (to the cluster) entities (such as storage arrays), this is left to the user to configure. 22.1.25. .spec.defaultNetwork.ovnKubernetesConfig.ipv4 Description ipv4 allows users to configure IP settings for IPv4 connections.
