Testcontainer inside Openshift - Docker Non-root

[quentingosset]

Hello everyone,

I am facing a problem that is bothering me quite a bit, and I am not keen on the alternative of using an external database.
My problem is as follows:
I have a CICD under GitLab via GitLab runners (https://docs.gitlab.com/runner/configuration/configuring_runner_operator/), all installed on OpenShift. As you can see, GitLab Runner Operator and GitLab Runner pod run as non-root users. So I'm facing a problem because when I try to launch testcontainer on my pipeline, I get the error “could not find a valid Docker environment.” This is normal because after running a few tests, I have absolutely no Docker created. Is there a way to work around this problem with a “non-root” mode of Docker in TestContainer? I found this docker:dind-rootless while trying to add it as a complement to TestContainer, but it doesn't seem to work.

Does anyone have any ideas?
Thanks
