ImageTagMirrorSet [config.openshift.io/v1]
Description
ImageTagMirrorSet holds cluster-wide information about how to handle registry mirror rules on using tag pull specification. When multiple policies are defined, the outcome of the behavior is defined on each field. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer).

The image pull specification provided to the pod will be compared to the source locations described in imageTagMirrors and the image may be pulled down from any of the mirrors in the list instead of the specified repository allowing administrators to choose a potentially faster mirror. To use mirrors to pull images using digest specification only, users should configure a list of mirrors using “ImageDigestMirrorSet” CRD. If the image pull specification matches the repository of “source” in multiple imagetagmirrorset objects, only the objects which define the most specific namespace match will be used. For example, if there are objects using quay.io/libpod and quay.io/libpod/busybox as the “source”, only the objects using quay.io/libpod/busybox are going to apply for pull specification quay.io/libpod/busybox. Each “source” repository is treated independently; configurations for different “source” repositories don’t interact.

When multiple policies are defined for the same “source” repository, the sets of defined mirrors will be merged together, preserving the relative order of the mirrors, if possible. For example, if policy A has mirrors a, b, c
and policy B has mirrors c, d, e
, the mirrors will be used in the order a, b, c, d, e
. If the orders of mirror entries conflict (e.g. a, b
vs. b, a
) the configuration is not rejected but the resulting order is unspecified. Users who want to use a deterministic order of mirrors, should configure them into one list of mirrors using the expected order.

Property | Type | Description |

|
| mirrorSourcePolicy defines the fallback policy if fails to pull image from the mirrors. If unset, the image will continue to be pulled from the repository in the pull spec. sourcePolicy is valid configuration only when one or more mirrors are in the mirror list. |
|
| mirrors is zero or more locations that may also contain the same images. No mirror will be configured if not specified. Images can be pulled from these mirrors only if they are referenced by their tags. The mirrored location is obtained by replacing the part of the input reference that matches source by the mirrors entry, e.g. for registry.redhat.io/product/repo reference, a (source, mirror) pair .redhat.io, mirror.local/redhat causes a mirror.local/redhat/product/repo repository to be used. Pulling images by tag can potentially yield different images, depending on which endpoint we pull from. Configuring a list of mirrors using “ImageDigestMirrorSet” CRD and forcing digest-pulls for mirrors avoids that issue. The order of mirrors in this list is treated as the user’s desired priority, while source is by default considered lower priority than all mirrors. If no mirror is specified or all image pulls from the mirror list fail, the image will continue to be pulled from the repository in the pull spec unless explicitly prohibited by “mirrorSourcePolicy”. Other cluster configuration, including (but not limited to) other imageTagMirrors objects, may impact the exact order mirrors are contacted in, or some mirrors may be contacted in parallel, so this should be considered a preference rather than a guarantee of ordering. “mirrors” uses one of the following formats: host[:port] host[:port]/namespace[/namespace…] host[:port]/namespace[/namespace…]/repo for more information about the format, see the document about the location field: https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md#choosing-a-registry-toml-table |
|
| source matches the repository that users refer to, e.g. in image pull specifications. Setting source to a registry hostname e.g. docker.io. quay.io, or registry.redhat.io, will match the image pull specification of corressponding registry. “source” uses one of the following formats: host[:port] host[:port]/namespace[/namespace…] host[:port]/namespace[/namespace…]/repo [.]host for more information about the format, see the document about the location field: https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md#choosing-a-registry-toml-table |

| 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. |
|
| 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 previous 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 next key, but from the latest snapshot, which is inconsistent from the previous 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 “next 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. |

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. |
