Hello all,

I've been playing a bit with Quarkus and test containers/dev services on
Fedora
34. I have been able to make things work with podman from dnf and the
following
setup:

sudo dnf install podman
systemctl --user start podman.socket
export DOCKER_HOST=unix:///run/user/${UID}/podman/podman.sock

There is an issue with test-containers/podman currently which makes the
setup
a little flaky if the user doesn't have the container they want to use
present
in their local repository[0].

Other than that, the set up works as far as I can see. Is this something
we may
want to document how to run with Quarkus in Quarkus docs? Especially
considering the upcoming licencing changes for docker.

Thanks and best regards,
--MJ

Does this setup also work with docker-maven-plugin ?

Yes, the setup works with the plugin. Some containers have issues with
startup on default, like DB2, but so far, I have not been able to
investigate further.

Thanks Michal! We definitely need to document this. Will you take care of it?

Hi all,

I've been looking for a place where to include the possible podman configuration, but I haven't found any fitting spot. The native build things already work on docker and testcontainer/dev services stuff is spread across the respective areas.

Have I missed anything? Does anybody have a better idea what could be a good place to include it?

It will need a new config object (quarkus.container ?). As much as possible this should be unified IMHO, so we have all this related config in one place, and deprecate older config items.

It is not specific for us - it is just to enable running test containers/dev services with podman. It is these three shell commands in F34:

sudo dnf install podman
systemctl --user start podman.socket
export DOCKER_HOST=unix:///run/user/${UID}/podman/podman.sock

we don't install nor run docker for user ...also only a small fraction would be running on fedora so not sure these make sense to run for user .

export DOCKER_HOST=unix:///run/user/${UID}/podman/podman.sock

this is relevant but different per OS and in future versions of podman this will be default setup....so not sure we would put this...shouldn't we be
setting a testcontainer option directly rather than overwrite docker host ?

One of the long term goals I have hoped for is some form of auto install for Quarkus that fetches everything you need, starting from a cut and paste on the Quarkus website (e.g a jbang script - since it already does jdk install)

I think downloading and installing podman belongs there. When it gets to Quarkus bootstrap, we should detect podman and use it appropriately (at some point preferring it to docker). I agree with Max that testcontainer API is probably the best config point (and we can contribute patches to their community there to improve if necessary). We might want to display instructions if we can’t find one or the other container runtimes.

Hi all,

I've found a bit of time and finally made a little write-up about config for Podman with dev services/testcontainers on Linux.

I wasn't sure where in docs to put it, so a blog post seemed like a way to go.

PR: https://github.com/quarkusio/quarkusio.github.io/pull/1189

That's really awesome, good job!

Can you create a guide too?
