feature request: composePsFormat in config (analog of psFormat)

[id-ilych]

Description

For the docker ps there is a possibility to define a default format in ~/.docker/config.json
For example: "psFormat": "table {{ .Names }}\t{{ .Image }}\t{{ .Status }}\t{{ .Ports }}"

It would be nice to have a similar option for docker compose ps.

In the docker/cli it is implemented as

func runPs(dockerCli command.Cli, options *psOptions) error {
	// ...
	if len(options.format) == 0 {
		// load custom psFormat from CLI config (if any)
		options.format = dockerCli.ConfigFile().PsFormat
	}
	// ...
}

I could try implementing it myself but I am not so familiar with the codebase so I am not sure how to use the same approach because this config file is defined in the other project which should probably be agnostic of compose-specific configurations...

This has already been fixed by #10918

Hello @ndeloof 👋

Thank you for pointing to that change I missed 🙇
Do I understand correctly that introduced change applies the same psFormat value from ~/.docker/config.json?
Do I understand correctly that it means I can't have {{ .Service }} there because that would break docker ps?

[ndeloof]

you indeed can't use this in your ~/.docker/config.json as this would break docker ps, but you can pass a docker ps format to compose, it will support same options

@ndeloof so could you suggest the approach that I could try implementing to enable having compose-specific configuration option in ~/.docker/config.json? Or would that just overcomplicate things and doesn't worth it?
