Do you have another workflow run showing the original error? https://github.com/Kutsuja/Node-Podman-OpenShift-CI-CD isn't a public repo, so the run logs aren't available.

Also, can you give an overview of the changes made to implement this feature? The formatting changes make it harder to spot the functional changes in the diffs.

Thanks!

Oh yeah sorry, I overlooked that.

Changelog

What I did was to add an option to use either docker or podman.

Error Logs

• Podman Fresh

1. This is the first run, with no cache found, expected.
   Every layer shares the same layerId in Post Podman Layer Caching, a problem.
2. This is the second run, loaded cache successfully, but didn't use cache when building.

• Docker to Podman transition

1. This is where docker caching is still working.
   This is both the original and expected behaviour, splendid.
2. This is a run on podman right after docker .
   We see in Podman Layer Caching, it did .. podman load .. and loaded the cache successfully.
   However, it didn't use the cache.
3. This is yet another podman run, same behaviour.

Noteworthy

Possible bug

We can see the coverage test drop from 100% to 50% in Build image, run lint/test (both Docker and Podman), I am not sure if this was due to the unit test.
Did limited testing and can't seem to replicate this with the old action, or without this action.

1. This is the first run.
2. This is the second run.

Other

Old log with same key as Docker to Podman transition

• Fresh Podman run

1. This is a fresh >run on podman, and there's no cache (yet), as expected.
   The problem being in the Post Podman Layer Caching, it failed to store layer caches as it failed to retrieve layerId.
2. This is a >second run, it retrieved the caches, loads them successfully, then decided not to use them.

I've been testing podman locally and it doesn't appear to be fully compatible with the docker CLI:

• podman save requires an extra flag -m to permit saving multiple images in a single archive; without that it only includes the first tag/digest specified.
• podman save fails if the output archive already exists.
• podman history seems to omit the digests for some intermediate images.
• podman load doesn't appear to populate the cache with the loaded images.

The first two can be worked around, but if the last is correct then this action can't be updated to support podman.

Ah, what a shame :{
