Make consistent lists exit for commands 'podman container list -a' and 'podman images'

[aeiris]

Feature request description

I suggest add the command 'podman containers' to list all containers, same exit of 'podman container list -a' but also modifying the schema (filters?) of the list to make it more compact as in 'podman images' exit.

This would intuitively pair with the 'podman images' to list images.

The list filters/schema could be:
CONTAINER ID | NAME | IMAGE | CREATED | STATUS or SIZE

Now fields are:
CONTAINER ID | IMAGE | COMMAND | CREATED | STATUS | PORTS | NAMES

Example:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
09cc4b895ba5 localhost/fedora-toolbox-base-41:latest toolbox --log-lev... 6 months ago Exited (143) 3 months ago fedora-toolbox

For podman images is:
REPOSITORY | TAG | IMAGE ID |CREATED | SIZE

Example:
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/fedora-node-base-41 latest 8ad1ce78440e 6 months ago 4.03 GB
localhost/fedora-toolbox-41 latest 9e19679632c7 6 months ago 5.62 GB
registry.fedoraproject.org/fedora-toolbox 41 53cbabee2cf6 6 months ago 2.21 GB

I noted also that 'podman images' output is more compact.

Suggest potential solution

I propose:

• add 'podman containers' command

• using a field schema for its output like:
  CONTAINER ID | NAME | IMAGE | CREATED | STATUS (and/or SIZE)

not showing COMMAND and PORTS fields
changing fields order NAMES

• make more compact the output format

Have you considered any alternatives?

Can be created an alias and custom schemas, but would be better having this command out-of-the-box

I rather not add a new command just to produce slightly different output of an existing command.

That way people like to see the output is subjective and I rather not go down the road of adding a ton of commands just to format the output differently. There is already --format to tweak the output as you like

podman ps -a --size  --format "table {{.ID}} {{.Names}} {{.Image}} {{.CreatedHuman}} {{.Size}}"

Also showing the size by default is a bad default as the container size is dynamic. The reason this is opt in is because it means we must walk every single container fs for all files to calculate its size. Unlike images they are not static as the container process could change them any time.

The size point is reasonable, thanks for clarifying.

I'm just proposing this sole intuitive command (a very usual action, I believe) for the sake of coherence and convenience:

• podman images = podman image list
• podman containers = [ podman container list -a | podman ps -a | podman container ps -a ]

Note that there is already some redundancy in podman commands (image,ps), but anyway 'podman images' exists and it's intuitive for a frequent action as the proposed command.

A friendly reminder that this issue had no activity for 30 days.

I think adding new commands with different formats is just confusing when --format already exists so I am going to close this
