OpenShift oc-mirror v2 ImageSetConfiguration mirror.additionalImages exact image references behavior and whether omitted tags are mirrored

💡 Result:

In the OpenShift oc-mirror v2 plugin, the mirror.additionalImages section of the ImageSetConfiguration is used to define specific container images for the mirroring process [1][2]. Regarding the behavior of image references and omitted tags: 1. Image Reference Requirements: You must provide an explicit registry hostname for every image listed under additionalImages [1][3][4]. Failing to include the explicit registry hostname can cause the plugin to mirror images to incorrect or unexpected target paths [1][4][5]. 2. Tag Behavior: - When a tag is specified in the name field (e.g., registry.redhat.io/ubi8/ubi:latest), that specific tag is used for the mirror operation [1][4][5]. - If no tag is provided in the name field, oc-mirror calculates and applies a tag based on the image’s partial digest [4][5]. - You can explicitly control the destination tag by using the optional targetTag field [4][5]. If targetTag is configured, it overrides the tag derived from the name field [4][5]. In summary, the plugin is designed to process the specific image reference provided. If you omit a tag in the name field, the plugin does not mirror all tags for that repository; instead, it automatically derives a tag from the image's digest to ensure a deterministic reference is mirrored [4][5].
