Only between podman-build, create, and run. podman-pod-create is too different. As usual I went with the podman-run version. This means keeping the word "flag" (which should be "option"), for ease of review. I will fix in my in-progress cleanup PR. For podman-build, I removed "during the build" and changed it to a note for that man page only. Signed-off-by: Ed Santiago <santiago@redhat.com>
Common Man Page Options
This subdirectory contains option (flag) names and descriptions
common to multiple podman man pages. Each file is one option. The
filename does not necessarily need to be identical to the option
name: for instance, hostname.container.md and hostname.pod.md
exist because the --hostname option is sufficiently different
between podman-{create,run} and podman-pod-{create,run} to
warrant living separately.
How
The files here are included in podman-*.md.in files using the @@option
mechanism:
@@option foo ! will include options/foo.md
The tool that does this is hack/markdown-preprocess. It is a python
script because it needs to run on readthedocs.io. From a given .md.in
file, this script will create a .md file that can then be read by
go-md2man, sphinx, anything that groks markdown. This runs as
part of make docs.
Special Substitutions
Some options are almost identical except for 'pod' vs 'container'
differences. For those, use <<text for pods|text for containers>>.
Order is immaterial: the important thing is the presence of the
string "pod" in one half but not the other. The correct string
will be chosen based on the filename: if the file contains -pod,
such as podman-pod-create, the string with pod (case-insensitive)
in it will be chosen.
The string <<subcommand>> will be replaced with the podman subcommand
as determined from the filename, e.g., create for podman-create.1.md.in.
This allows the shared use of examples in the option file:
Example: podman <<subcommand>> --foo --bar
As a special case, podman-pod-X becomes just X (the "pod" is removed).
This makes the pod-id-file man page more useful. To get the full
subcommand including 'pod', use <<fullsubcommand>>.
