I couldn't find anybody pointing out the missing support for container runtimes other than Docker, so here I go:

As a user of Fedora Silverblue, I don't have out-of-the-box docker builtin with my OS, but instead podman (a daemonless and "rootless" userspace container engine). For purposes of building images and running containers it's directly compatible with docker, however as it doesn't have a daemon, there's no way to interact with it using go docker bindings (like act does).

From what I understand, act uses docker bindings in order to

• resolve and pull images
• create and execute containers

All of this is possible with podman as well, so a solution could be to replace the direct docker bindings with an abstraction layer that would default to docker, but allows the user to select podman (or another binding) to interact with containers or images. I would be interested in helping to get this to work, and want to raise this issue to ask for support on this topic.

But GitHub Actions don't support other container runtimes do they?

Honestly I don't know what runtimes they're using. They're talking about "docker actions" in the docs, but as the actions spec only exposes very superficial parts of the underlying system it could really be anything.

As both docker and podman use the same kind of image specification, images are compatible with both and other runtimes.

From my POV, there's no strong requirement to lock in with docker for the sake of running actions locally or in CI.

A daemonless container runtime could even be beneficial for environments where users don't have enough access rights on their machine to install or control a docker daemon (think CI or corporate environments).

It's a big pain point to use Docker on Fedora 32. It's not supported out of the box.

Issue is stale and will be closed in 7 days unless there is new activity

Is there any chance this issue can be reopened? Looks like Podman support still isn't present.

podman support is something I'm tracking but no idea when will that gets done. Feel free to submit PR if you have something done.

For podman API service can be run with.

podman system service -t 0
# -t 0  means no timeout

Then it is possible to run act with DOCKER_HOST variable.

DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock act

That still didn't work for me. )

That's good info! You likely need the FQDN for the image. You can also set docker.io in the short names conf. I'm away from my computer but will try this out on my side

That may be the case for you but others can and will have more issues when trying to run act with podman. I don't recommend using podman right now unless you are persistent or trying to add podman support to act.

Note, podman has pretty much full compatibility with docker API now. Rootful as of 3.0.0, and rootless as of 3.2.0. All you have to do is enable the podman socket and export docker host:

systemctl enable --now --user podman.socket
systemctl start --user podman.socket
export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock

This seems to work for me. I did a quick test using one of the testdata files:

I also ran the test suites. pkg/common and pkg/model worked fine. I'm assuming that is because there is no docker usage in those packages.

The pkg/container test suite return a single error because docker pull pulling the wrong image when specifying platform. I've raised a bug for podman https://github.com/containers/podman/issues/10977, as it affects docker cli too.

The pkg/runner test suite expectedly picked up a lot more issues. The following tests failed:

• TestRunEvent/basic
• TestRunEvent/shells/python
• TestRunEvent/uses-docker-url
• TestRunEvent/remote-action-docker
• TestRunEvent/local-action-docker-url
• TestRunEvent/local-action-dockerfile
• TestRunEvent/basic#01

Tried to debug these but I struggled to work my way around the code (mostly trying to figure out where the errors are happening). Anyway, the only two errors were the previous mentioned error of the image not being found (only for the shells/python test case), the rest had the following error:

    runner_test.go:79: 
        	Error Trace:	runner_test.go:79
        	Error:      	Expected nil, but got: unable to upgrade to tcp, received 409

        	Messages:   	/tmp/act/pkg/runner/testdata/basic
    --- FAIL: TestRunEvent/basic#01 (9.63s)

Not really sure what it means.

I decided to document the method I used to get act running on fedora 34 x86-64:

—

First, change the line in /etc/containers/registries.conf to read:

short-name-mode="permissive"

Also run sudo dnf install podman-docker.

Per https://github.com/nektos/act/issues/303#issuecomment-882069025 run these commands:

systemctl enable --now --user podman.socket
systemctl start --user podman.socket
export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock

Then you can invoke act.

Similar to @shlomif 's note above:

sudo pacman -S podman-docker

export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock

@Loki-Afro ,

If we check podman's API server logs...

journalctl --user -u podman.service

We can find podman's API is saying something like this:

Interestingly podman is returning a 200 on a failure of PUT API call. That means, the mkdir command from act failed but docker.client.CopyToContainer passed. https://github.com/moby/moby/blob/7b9275c0da707b030e62c96b679a976f31f929d3/client/container_copy.go#L47

However though, since the directory doesn't actually exist, the following GET calls to the API returned 404. So this code failed.

https://github.com/nektos/act/blob/96cf907c5e1f4761ef6d91bb8e22487747a77f6b/pkg/container/docker_run.go#L455

---

I see two issues here:

1. podman should return a 403 according to the API [1]
2. act should create a rw path in container so we are allowed to write files into the filesystem.

[1] https://docs.docker.com/engine/api/v1.41/#operation/PutContainerArchive

2. act should create a rw container so we are allowed to write files into the filesystem.

why?

@catthehacker ,

We are surely writing data into it, aren't we?

https://github.com/nektos/act/search?q=CopyToContainer&type=code

We are surely writing data into it, aren't we?

Yes, but why we should do that? It works just fine in Docker

Also, what is rw container?

In docker, act is using the root permission to setup this directory, which would for sure pass the check, root can write anything inside the containers anyways (leaky abstraction!).

However, in (rootless) podman, writing to /var is not allowed.

docker exec cmd=[mkdir -m 0777 -p /var/run/act] user=root

Here we are in fact (ab)using the root permission to write to the directory that we are technically not allowed to, I understand that act needs to write files inside the container, we should choose more explicit ways (e.g. rw volumes) for such directory creation.

But it's already a volume that is not restricted by ReadOnly option.

Also, the issue is not because of rootless daemon since I can reproduce it just fine in rootful podman

Could it be because podman often requires --security-opt label=disable option to make things work with the volumes?

No, it still fails.

@catthehacker, I spent some time digging into this issue. :)

The below POC script is mimicking what act is doing in run_context.go, with some cross referenced debug logs from dockerd (to get POST parameters).

Running this script against the podman-docker API server, we can find the following from podman's API logs, as I pointed out earlier.

level=error msg="copier: put: error creating \"/run/act/act\": mkdir /run/act/act: read-only file system"

If we check the container spec generated by podman, we can find these are mounted as ro volumes.

$ podman inspect act-CI-build | jq .[0].HostConfig.Binds
[
  "act-toolcache:/toolcache:ro,rprivate,nosuid,nodev,rbind",
  "act-CI-build-env:/var/run/act:ro,rprivate,nosuid,nodev,rbind",
  "/run/user/1000/podman/podman.sock:/var/run/docker.sock:rw,rprivate,nosuid,nodev,rbind",
  "/tmp/manualaction:/tmp/manualaction:rw,rprivate,nosuid,nodev,rbind"
]

As the same behavior act is seeing, we failed to extract the tarball to this mount point.

$ podman exec -it act-CI-build ls /var/run/act/act
ls: cannot access '/var/run/act/act': No such file or directory

---

On the other hand, if we change the mount target to "/var/run/act:rw" ...

    "Mounts": [                                                                 
      {                                                                         
        "Source": "act-toolcache",                                              
        "Target": "/toolcache",                                                 
        "Type": "volume"                                                        
      },                                                                        
      {                                                                         
        "Source": "act-CI-build-env",                                           
        "Target": "/var/run/act:rw",                     <--------------                                                                                                      
        "Type": "volume"                                                        
      }                                                                         
    ]

We're able to see the proper rw mountpoint been created by podman.

$ podman inspect act-CI-build | jq .[0].HostConfig.Binds
[
  "act-toolcache:/toolcache:ro,rprivate,nosuid,nodev,rbind",
  "act-CI-build-env:/var/run/act:rw:ro,rprivate,nosuid,nodev,rbind",      <----
  "/run/user/1000/podman/podman.sock:/var/run/docker.sock:rw,rprivate,nosuid,nodev,rbind",
  "/tmp/manualaction:/tmp/manualaction:rw,rprivate,nosuid,nodev,rbind"
]

Also, we're able to see the contents of tarball inside the container.

$ podman exec -it act-CI-build ls /var/run/act/act
bar  foo

---

Per podman's man page [1]:

   Options specific to bind:

      · ro, readonly: true or false (default).

I hope the above helps. :)

hey! is there a docker image you are using to run podman?

@Loki-Afro , @catthehacker , with both bugs fixed in podman, I'm able to run act with podman w/o problems again.

@georgettica , are you asking the image that act uses to run workflows? that'd be catthehacker/ubuntu:act-latest.

I meant the image to run tests with podman. I guessed each had an image that can be pulled so additional local tests can follow

Will check once podman will finish building on my machine.

I don't understand the question. There isn't any podman image for tests nor container runtime should be tested via any image.

@catthehacker thanks, here's the version on my box.

$ podman version
Version:      3.4.4
API Version:  3.4.4
Go Version:   go1.17.4
Git Commit:   f6526ada1025c2e3f88745ba83b8b461ca659933

@georgettica , sorry I still don't understand the question. Can you please elaborate what we're trying to do here? If we're adding more tests to podman, you can follow the API calls in the script above (https://github.com/nektos/act/issues/303#issuecomment-979752688)

I still get failure though
