After pulling/creating an image of a foreign platform, Podman will happily use it when looking it up in the local storage and will not pull down the image matching the host platform. As discussed in #12682, the reasoning for it is Docker compatibility and the fact that user already rely on the behavior. While Podman is now emitting a warning when an image is in use not matching the local platform, the documentation was lacking that information.

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.
