./hack/podmanv2-retry will first invoke $PODMAN_V2 with given
arguments. If that fails with any of the following errors:
unrecognized command
unknown flag
unknown shorthand
...it will run $PODMAN_FALLBACK with the same arguments.
Output and exit code will be those of the final podman command,
although be aware that stderr and stdout are combined.
This is a quick-hack script intended for use in v2 testing, to
test implemented commands without noise from unimplemented ones.

# podman-try - try running a command via PODMAN1; use PODMAN2 as fallback
|
|
#
|
|
# Intended for use with a podmanv2 client. If a command isn't yet
|
|
# implemented, fall back to regular podman:
|
|
#
|
|
# Set PODMAN_V2 to the path to a podman v2 client
|
|
# Set PODMAN_FALLBACK to the path to regular podman
|
|
#
|
|
# THIS IS IMPERFECT. In particular, it will not work if stdin is redirected
|
|
# (e.g. 'podman ... < file' or 'something | podman'); nor for anything
|
|
# that generates continuous output ('podman logs -f'); and probably more
|
|
# situations.
