4.4. Inspecting local images

Prerequisites

• The container-tools meta-package is installed.
• A pulled image is available on the local system.

Procedure

• Inspect the registry.redhat.io/ubi10/ubi image:

  $ podman inspect registry.redhat.io/ubi10/ubi
  …
   "Cmd": [
          "/bin/bash"
      ],
      "Labels": {
          "architecture": "x86_64",
          "build-date": "2020-12-10T01:59:40.343735",
          "com.redhat.build-host": "cpt-1002.osbs.prod.upshift.rdu2.redhat.com",
          "com.redhat.component": "ubi10-container",
          "com.redhat.license_terms": "https://www.redhat.com/...,
      "description": "The Universal Base Image is ...
      }
  ...

  The "Cmd" key specifies a default command to run within a container. You can override this command by specifying a command as an argument to the podman run command. This ubi10/ubi container will execute the bash shell if no other argument is given when you start it with podman run. If an "Entrypoint" key was set, its value would be used instead of the "Cmd" value, and the value of "Cmd" is used as an argument to the Entrypoint command.
