Dockstore-cli: Support Podman (alternatrive Docker) or workaround?

My environment is Fedora 36. In the Red Hat (RPM-based) Linux distributions such as Fedora, CentOS stream, and RHEL, the Podman is encouraged rather than Docker. Most of the Podman commands are common with the Docker.

$ dockstore tool launch --local-entry hello.wdl --json hello.inputs.json
20:00:30.838 [main] ERROR io.dockstore.client.cli.ArgumentUtility - Current version : 1.12.0-rc.0

20:00:30.841 [main] ERROR io.dockstore.client.cli.ArgumentUtility - You do not have the most recent stable release of Dockstore.
Please upgrade with the following command:
   dockstore --upgrade
WARNING: Docker is not running. If this tool uses Docker, it will fail.

Does the Dockstore CLI work with the Podman without Docker? Or is there a workaround such as below?

$ cd /usr/local/bin
$ sudo ln -s $(which podman) docker

Hi,
We have not experimented much with podman, we have experimented with rootless Docker and Singularity ( Docker Alternatives — Dockstore documentation ).

For what it’s worth, the message above is just a warning ( dockstore-cli/AbstractEntryClient.java at 1.12.0 · dockstore/dockstore-cli · GitHub ) and should not stop execution of the tool. Did the tool execution fail in the end?

The Dockstore CLI is integrated with Cromwell for WDL and cwlrunner for CWL. It looks like you’re running with WDL, so it looks there are a couple attempts to run Cromwell with Podman here. cromwell + podman · Issue #6660 · broadinstitute/cromwell · GitHub

Let us know how well it works!

@dyuen thanks for your inputs!

Unfortunately the dockstore tool launch failed, and here is the full log when running dockstore tool launch ... on my local with the podman and symbolic linked docker.

The ticket cromwell + podman · Issue #6660 · broadinstitute/cromwell · GitHub says java -jar cromwell-75.jar server but the dockstore tool launch executes the java -jar cronwell-NN.jar run’.

Perhaps, I might need to adjust the executed podman’s security setting like the rootless docker. Docker Alternatives — Dockstore documentation

I was able to run with the podman (and the docker symbolic link) when disabling SE Linux. The cause was not the podman but the enabled SE Linux

So, below is the temporary workaround.
