I don't see how this helps.
If you actually care for compatibility you need to match the actual commands with their input and output.

Per https://docs.docker.com/engine/reference/commandline/trust/
there is the inspect, key, revoke, sign, signer command, but no set or show which you add here.

It makes it more discoverable. We can look at fixing up the others. But for now users who do podman trust see no failure.

I disagree, nobody uses podman trust. This is just a stub command to attach subcommands, if you want to be docker compatible you actually need to implement the correct subcommands. As of now you add podman trust set/show which do not exists on docker, so what is the point?

[rhatdan]

Let's discuss at the next standup, and get consensus. My goal was to allow users to discover how Podman defines trust.

podman trust
Error: unrecognized command `podman trust`
Try 'podman --help' for more information

Versus

 $ ./bin/podman trust
Manage container image trust policy

Description:
  Manages which registries you trust as a source of container images based on their location.
  The location is determined by the transport and the registry host of the image.  Using this container image docker://quay.io/podman/stable as an example, docker is the transport and quay.io is the registry host.

Usage:
  podman trust [command]

Available Commands:
  set         Set default trust policy or a new trust policy for a registry
  show        Display trust policy for the system

Error: missing command 'podman trust COMMAND'

For the record: consensus was to not create an alias but return a meaningful error to users that would direct them to image trust.

Closing for now, since I have no time to work on it, and it would be complicated to implement.
