Image [config.openshift.io/v1] - Config APIs | API reference | OpenShift Container Platform 4.16

Specification
API endpoints

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).

`apiVersion`	`string`	APIVersion defines the versioned schema of this representation of an object.

`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.

Property Type Description

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.
