As of conmon 2.2.0, conmon supports log file rotation via --log-rotate
and --log-max-files. This commit exposes those options through Podman's
REST API, specgen model, CLI (--log-opt), and libpod container runtime
so that users managing containers through the API can configure conmon
log rotation settings.
New --log-opt keys accepted:
max-file=<n> Maximum number of rotated log backup files.
Setting this implicitly enables log rotation.
log-rotate=true|false Explicitly enable or disable log rotation.
Options flow:
CLI / REST API
-> specgenutil parses and validates new opts
-> specgen.LogConfig.Options carries max-file and log-rotate
-> generate.MakeContainerFromSpec calls WithLogMaxFiles/WithLogRotate
-> libpod stores LogMaxFiles and LogRotate in ContainerConfig
-> oci_conmon_common.go passes --log-max-files/--log-rotate to conmon
podman inspect now reflects rotation settings in HostConfig.LogConfig.Config.

API Reference
The latest online documentation is
automatically generated by the readthedocs build process. It uses redoc to render the
swagger.yml file, the swagger is build and injected as static resource in the readthedocs
build process, see the .readthedocs.yaml file.
The swagger file can be downloaded from https://docs.podman.io/en/latest/_static/swagger.yaml.
Note the latest link always contains the latest yaml from the main branch, if you like a specific
version replace latest with the version, i.e. for v6.0.0 https://docs.podman.io/en/v6.0.0/_static/swagger.yaml.
Also this new process is only done since v5.8.4. Earlier swagger.yml files where
uploaded here.
Local Testing
To build standard man pages, run make docs. Results will be in docs/build/man.
To build HTMLized man pages: Assuming that you have the dependencies installed, then also install (showing Fedora in the example):
$ sudo dnf install python3-sphinx python3-recommonmark
$ pip install sphinx-markdown-tables myst_parser
(The above dependencies are current as of 2022-09-15. If you experience problems, please see requirements.txt in this directory, it will almost certainly be more up-to-date than this README.)
After that completes, cd to the docs directory in your Podman sandbox and then do make html.
You can then preview the html files in docs/build/html with:
python -m http.server 8000 --directory build/html
...and point your web browser at http://localhost:8000/
