podman push does not preserve docker manifest type as of podman v5.1.0 #22976

RichardShiao · 2024-06-12T07:23:00Z

Issue Description

When building an image using the format flag, podman build --format=docker produces an image with ManifestType application/vnd.docker.distribution.manifest.v2+json.

Building is working as expected, but pushing is showing new behavior.

As of podman 5.0.3, podman push for this image preserved the type:
application/vnd.docker.distribution.manifest.v2+json

As of podman 5.1.0 (also reproduced in latest version 5.1.1), podman push is overwriting the type:
application/vnd.oci.image.manifest.v1+json

Is this a bug? Or new design?

Steps to reproduce the issue

Will show steps for both podman 5.0.3 and 5.1.1:

podman 5.0.3 shows expected behavior

Describe the results you received

As of podman 5.1.0 (also reproduced in latest version 5.1.1), podman push is overwriting the type:
application/vnd.oci.image.manifest.v1+json

Describe the results you expected

As of podman 5.0.3, podman push for this image preserved the type:
application/vnd.docker.distribution.manifest.v2+json

Was expecting the same behavior in later versions of podman as well.

@nalind do you figure this is on the Podman side or something vendored in?

nalind · 2024-06-12T14:10:35Z

I was able to build and push an image using the provided Dockerfile. If you're using Fedora, like I am, then pushing the built image with podman push produces an OCI-format manifest in the registry because my system is apparently configured to use zstd compression in /usr/share/containers/containers.conf. This compression format isn't something that can be expressed in the docker format, so it ends up being converted to OCI format on the fly. The result can be confirmed by inspecting the image in the registry using skopeo inspect --raw. Pushing with --format=docker writes an image to the registry in the docker format using gzip compression.

If you're not using Fedora, then more diagnostic information would be really helpful here. The full podman info output also provides information and inferences about configuration settings and the kernel version. Pushing with --log-level=debug is also helpful for getting some insight into what the underlying libraries are doing at the time.

@baude, I think the logic controlling what happens here is mostly in containers/image and partially in containers/storage, but I could see this as being an expected consequence of setting an [engine] compression_type in containers.conf.

RichardShiao · 2024-06-12T20:14:55Z

@nalind Thanks for checking! Are you also able to reproduce the old behavior when using 5.0.3 - that it does not change the Docker format to OCI?

Can you confirm if the new behavior as of 5.1.0 is a bug? If we have an image already built in Docker format, then I would expect pushing it without any flags to change the format should still retain the same format. That is what we see in earlier versions of podman.

Or is this behavior by design now to default pushes to OCI format? So to preserve Docker format, we should use --format=docker for both builds and pushes?

Here is my current podman info:

I was not able to reproduce different behavior with a copy of 5.0.3 built from source, but if you're using a packaged version of 5.0.3, it may have come with a containers.conf that did include the configuration change. At any rate, a --format=docker shouldn't hurt when pushing an image.

Check to see if zstd:chunked is set as compression-format.

podman push --help | grep compression-format
--compression-format string compression format to use (default "zstd:chunked")

@nalind Thanks for checking your copy of 5.0.3. I thought it was something consistently reproducible in code, but sounds like it is packaging dependent.

For more context, the original place we saw impact was from our scripts that use images from quay.io podman/stable releases. We were using stable:latest, which has been working for us for a few years. But a few days ago, we started seeing this manifest type issue. I'm guessing it is correlated to when latest tag switched to 5.1.0? As a workaround, we pinned the image to stable:v5.0.2 and that restored the old behavior.

For further testing, I also tried podman on my local (Macbook), which was running podman v5.0.3 installed via brew. I then installed podman v5.1.1 via brew. And the test results are what I posted above.

@rhatdan , here is what I get from my Mac, now running v5.1.1 from brew:
podman push --help | grep compression-format

      --compression-format string   compression format to use

Did something change with packaging for both these methods (quay.io repository and brew)?

see #22813
and containers/common#2048

This was a packaging bug as zstd:chunked should only be enabled on fedora 41, so this will be fixed next time the machine image is rebuild
