I think this PR fixes #336 after all. |

Ephemeral COPR build failed. @containers/packit-build please check. |
At present it's not possible to ship properly labeled logs when using podman and tools like podman-compose. Container labels are lost which makes it much harder to understand where a particular log line originated from. Log processing and analysis is significantly more inconvenient as well, because it's hard to group related logs, e.g. coming from the same compose project. This commit implements the parts necessary to annotate log messages with container labels. Each label and value pair is specified via --log-label LABEL=VALUE arguments.

@haircommander Would it be possible to release new version of conmon with this PR? I think containers/podman#26203 depends on new version of conmon. If new release is too early, I'm sorry for the noise and will wait for whenever a release will be made. |

It looks wrong to me...
It should be if (tag) { maybe?

This commit implements the parts necessary to annotate log messages with container labels. Each label and value pair is specified via --log-label LABEL=VALUE arguments.
This PR was initially based on #553 and ultimately was reworked enough that there's little semblance to the original PR anymore. Attribution is still preserved in commit message. The following is the changes from the 553 PR:
--log-labelbeing used with k8s-filepodmanand currently runs in production. Podman PR: libpod: Implement --log-opt label=LABEL=Value podman#26203.Fixes #336.
