As documented in the issue there is no way to wait for system units from the user session[1]. This causes problems for rootless quadlet units as they might be started before the network is fully up. TWhile this was always the case and thus was never really noticed the main thing that trigger a bunch of errors was the switch to pasta. Pasta requires the network to be fully up in order to correctly select the right "template" interface based on the routes. If it cannot find a suitable interface it just fails and we cannot start the container understandingly leading to a lot of frustration from users. As there is no sign of any movement on the systemd issue we work around here by using our own user unit that check if the system session network-online.target it ready. Now for testing it is a bit complicated. While we do now correctly test the root and rootless generator since commit ada75c0bb8 the resulting Wants/After= lines differ between them and there is no logic in the testfiles themself to say if root/rootless to match specifics. One idea was to use `assert-key-is-rootless/root` but that seemed like more duplication for little reason so use a regex and allow both to make it pass always. To still have some test coverage add a check in the system test to ask systemd if we did indeed have the right depdendencies where we can check for exact root/rootless name match.

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/
