--health-log-destination flags These flags can affect the output of the HealtCheck log. Currently, when a container is configured with HealthCheck, the output from the HealthCheck command is only logged to the container status file, which is accessible via `podman inspect`. It is also limited to the last five executions and the first 500 characters per execution. This makes debugging past problems very difficult, since the only information available about the failure of the HealthCheck command is the generic `healthcheck service failed` record. - The `--health-log-destination` flag sets the destination of the HealthCheck log. - `none`: (default behavior) `HealthCheckResults` are stored in overlay containers. (For example: `$runroot/healthcheck.log`) - `directory`: creates a log file named `<container-ID>-healthcheck.log` with JSON `HealthCheckResults` in the specified directory. - `events_logger`: The log will be written with logging mechanism set by events_loggeri. It also saves the log to a default directory, for performance on a system with a large number of logs. - The `--health-max-log-count` flag sets the maximum number of attempts in the HealthCheck log file. - A value of `0` indicates an infinite number of attempts in the log file. - The default value is `5` attempts in the log file. - The `--health-max-log-size` flag sets the maximum length of the log stored. - A value of `0` indicates an infinite log length. - The default value is `500` log characters.

Podman Documentation
The online man pages and other documents regarding Podman can be found at Read The Docs. The man pages can be found under the Commands link on that page.

API Reference
The latest online documentation is
automatically generated by two cooperating automation systems based on committed upstream
source code. Firstly, the Cirrus-CI docs task builds
pkg/api/swagger.yaml and uploads it to a public-facing location (Google Storage Bucket -
an online service for storing unstructured data). Second, Read The Docs
reacts to the github.com repository change, building the content for the libpod documentation
site. This site includes for the API section,
some javascript which consumes the uploaded swagger.yaml file directly from the Google
Storage Bucket.
Since there are multiple systems and local cache is involved, it's possible that updates to documentation (especially the swagger/API docs) will lag by 10-or-so minutes. However, because the client (i.e. your web browser) is fetching content from multiple locations that do not share a common domain, accessing the API section may show a stack-trace similar to the following:
If reloading the page, or clearing your local cache does not fix the problem, it is
likely caused by broken metadata needed to protect clients from cross-site-scripting
style attacks. Please notify a maintainer
so they may investigate how/why the swagger.yaml file's CORS-metadata is
incorrect, or the file isn't accessible for some other reason.
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/
