Commanding the Digital Realms

The oc image command serves as the wielder's tool to inspect, configure, and retrieve information about container images within the castle's domain.

Mystical Options at Your Command

Behold the commands bestowed upon the keeper of this arcane tool:

  • oc image info: Gather insights into the properties and configurations of container images. Utilize options like --filter-by-os to manage specific types of images, e.g.:
