Docker compose (v2) up --log-level missing

[xydesa]

Description

The --log-level option doesn't seem to work in compose v2.

This page has replicated help text from the command line that seems to suggest it's been deprecated: https://docs.docker.com/compose/reference/

But it's not mentioned as not yet implemented or not to be implemented in this page: https://docs.docker.com/compose/compose-v2/

It's also not mentioned in any of the release notes (except when it was added to compose v1): https://github.com/docker/compose/releases?q=log-level&expanded=true

Nor can I find any other reference to this feature being deprecated. Is it actually deprecated? Is there any other way to get the equivalent behavior? If it is deprecated and expected to not work the docs need to be updated.

[ndeloof]

As a CLI plugin, compose logging is configured at top level docker command:
docker --log-level=debug compose xx ...

command line output on https://docs.docker.com/compose/reference/ is obsolete, docker compose --help doesn't list --log-level flag in any recent release. Let's fix this

Closing this issue as documentation has been updated
