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. For backward compatibility, users can still use OPENSHIFT_DEFAULT_REGISTRY environment variable but this setting overrides the environment variable. 11.2. API endpoints The following API endpoints are available: /apis/config.openshift.io/v1/images DELETE : delete collection of Image GET : list objects of kind Image POST : create an Image /apis/config.openshift.io/v1/images/{name} DELETE : delete an Image GET : read the specified Image PATCH : partially update the specified Image PUT : replace the specified Image /apis/config.openshift.io/v1/images/{name}/status GET : read status of the specified Image PATCH : partially update status of the specified Image PUT : replace status of the specified Image 11.2.1. /apis/config.openshift.io/v1/images Table 11.1. Global query parameters Parameter Type Description pretty string If 'true', then the output is pretty printed. HTTP method DELETE Description delete collection of Image Table 11.2. Query parameters Parameter Type Description allowWatchBookmarks boolean allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. continue string The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the key, but from the latest snapshot, which is inconsistent from the list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the " key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. fieldSelector string A selector to restrict the list of returned objects by their fields. Defaults to everything. labelSelector string A selector to restrict the list of returned objects by their labels. Defaults to everything. limit integer limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. resourceVersion string resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset resourceVersionMatch string resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset sendInitialEvents boolean sendInitialEvents=true may be set together with watch=true . In that case, the watch stream will begin with synthetic events to produce the current state of objects in the collection. Once all such events have been sent, a synthetic "Bookmark" event will be sent. The bookmark will report the ResourceVersion (RV) corresponding to the set of objects, and be marked with "k8s.io/initial-events-end": "true" annotation. Afterwards, the watch stream will proceed as usual, sending watch events corresponding to changes (subsequent to the RV) to objects watched. When sendInitialEvents option is set, we require resourceVersionMatch option to also be set. The semantic of the watch request is as following: - resourceVersionMatch = NotOlderThan is interpreted as "data at least as new as the provided resourceVersion`" and the bookmark event is send when the state is synced to a `resourceVersion at least as fresh as the one provided by the ListOptions. If resourceVersion is unset, this is interpreted as "consistent read" and the bookmark event is send when the state is synced at least to the moment when request started being processed. - resourceVersionMatch set to any other value or unset Invalid error is returned. Defaults to true if resourceVersion="" or resourceVersion="0" (for backward compatibility reasons) and to false otherwise. timeoutSeconds integer Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. watch boolean Watch for changes to the described resources and return them as a stream of add, update, and remove notifications. Specify resourceVersion. Table 11.3. HTTP responses HTTP code Reponse body 200 - OK Status schema 401 - Unauthorized Empty HTTP method GET Description list objects of kind Image Table 11.4.

Query parameters Parameter Type Description dryRun string When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed fieldManager string fieldManager is a name associated with the actor or entity that is making these changes. The value must be less than or 128 characters long, and only contain printable characters, as defined by https://golang.org/pkg/unicode/#IsPrint . fieldValidation string fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. 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. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present.
