Chapter 11. Image [config.openshift.io/v1]
Chapter 11. Image [config.openshift.io/v1] Description Image governs policies related to imagestream imports and runtime configuration for external registries. It allows cluster admins to configure which registries OpenShift is allowed to import images from, extra CA trust bundles for external registries, and policies to block or allow registry hostnames. When exposing OpenShift's image registry to the public, this also lets cluster admins specify the external hostname. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 11.1. 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 spec holds user settable values for configuration status object status holds observed values from the cluster. They may not be overridden. 11.1.1. .spec Description spec holds user settable values for configuration Type object Property Type Description additionalTrustedCA object additionalTrustedCA is a reference to a ConfigMap containing additional CAs that should be trusted during imagestream import, pod image pull, build image pull, and imageregistry pullthrough. The namespace for this config map is openshift-config. allowedRegistriesForImport array allowedRegistriesForImport limits the container image registries that normal users may import images from. Set this list to the registries that you trust to contain valid Docker images and that you want applications to be able to import from. Users with permission to create Images or ImageStreamMappings via the API are not affected by this policy - typically only administrators or system integrations will have those permissions. allowedRegistriesForImport[] object RegistryLocation contains a location of the registry specified by the registry domain name. The domain name might include wildcards, like '*' or '??'. externalRegistryHostnames array (string) externalRegistryHostnames provides the hostnames for the default external image registry. The external hostname should be set only when the image registry is exposed externally. The first value is used in 'publicDockerImageRepository' field in ImageStreams. The value must be in "hostname[:port]" format. registrySources object registrySources contains configuration that determines how the container runtime should treat individual registries when accessing images for builds+pods. (e.g. whether or not to allow insecure access). It does not contain configuration for the internal cluster registry. 11.1.2. .spec.additionalTrustedCA Description additionalTrustedCA is a reference to a ConfigMap containing additional CAs that should be trusted during imagestream import, pod image pull, build image pull, and imageregistry pullthrough. The namespace for this config map is openshift-config. Type object Required name Property Type Description name string name is the metadata.name of the referenced config map 11.1.3. .spec.allowedRegistriesForImport Description allowedRegistriesForImport limits the container image registries that normal users may import images from. Set this list to the registries that you trust to contain valid Docker images and that you want applications to be able to import from. Users with permission to create Images or ImageStreamMappings via the API are not affected by this policy - typically only administrators or system integrations will have those permissions. Type array 11.1.4. .spec.allowedRegistriesForImport[] Description RegistryLocation contains a location of the registry specified by the registry domain name. The domain name might include wildcards, like '*' or '??'. Type object Property Type Description domainName string domainName specifies a domain name for the registry In case the registry use non-standard (80 or 443) port, the port should be included in the domain name as well. insecure boolean insecure indicates whether the registry is secure (https) or insecure (http) By default (if not specified) the registry is assumed as secure. 11.1.5. .spec.registrySources Description registrySources contains configuration that determines how the container runtime should treat individual registries when accessing images for builds+pods. (e.g. whether or not to allow insecure access). It does not contain configuration for the internal cluster registry. Type object Property Type Description allowedRegistries array (string) allowedRegistries are the only registries permitted for image pull and push actions. All other registries are denied. Only one of BlockedRegistries or AllowedRegistries may be set. blockedRegistries array (string) blockedRegistries cannot be used for image pull and push actions. All other registries are permitted. Only one of BlockedRegistries or AllowedRegistries may be set. containerRuntimeSearchRegistries array (string) containerRuntimeSearchRegistries are registries that will be searched when pulling images that do not have fully qualified domains in their pull specs. Registries will be searched in the order provided in the list. Note: this search list only works with the container runtime, i.e CRI-O. Will NOT work with builds or imagestream imports. insecureRegistries array (string) insecureRegistries are registries which do not have a valid TLS certificates or only support HTTP connections. 11.1.6. .status Description status holds observed values from the cluster. They may not be overridden. Type object Property Type Description externalRegistryHostnames array (string) externalRegistryHostnames provides the hostnames for the default external image registry. The external hostname should be set only when the image registry is exposed externally. The first value is used in 'publicDockerImageRepository' field in ImageStreams. The value must be in "hostname[:port]" format. internalRegistryHostname string internalRegistryHostname sets the hostname for the default internal image registry. The value must be in "hostname[:port]" format. This value is set by the image registry operator which controls the internal registry hostname. 11.2.

Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields.
