The rather raw and scarce output of `podman auto-update` has been a thorn in my eyes for a longer while. So far, Podman would only print updated systemd units, one per line, without further formatting. Motivated by issue #9949 which is asking for some more useful information in combination with a dry-run feature, I sat down and reflected which information may come in handy. Running `podman auto-update` will now look as follows: ``` $ podman auto-update Trying to pull [...] UNIT CONTAINER IMAGE POLICY UPDATED container-test.service 08fd34e533fd (test) localhost:5000/busybox registry false ``` Also refactor the spaghetti code in the backend a bit to make it easier to digest and maintain. For easier testing and for the sake of consistency with other commands listing output, add a `--format` flag. The man page will get an overhaul in a follow up commit.

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
Assuming that you have the dependencies installed, then also install (showing Fedora in the example):
# dnf install python3-sphinx python3-recommonmark
# pip install sphinx-markdown-tables
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
