Hi, folks!
I recently started an Elixir project and due to my knowledge with Testcontainers in a Java Spring Boot application stack I stumbled over testcontainers-elixir and wanted to give it a try.
But registering testcontainers-elixir in my test_helper.exs I only gets me some :badarg error when executing mix test:
** (EXIT from #PID<0.99.0>) :badarg
What I already found out:
- Testcontainers per se works on my machine in my Java Spring Boot application project.
- This seems to be an issue in combination with SELinux. Because when temporarily disabling SELinux by using
setenforce 0 then mix test actually runs without errors.
- I added
ryuk.container.privileged=true to my ~/.testcontainers.properties but this does not solve the issue.

So... My main question would be: What would I need to do, to make testcontainers-elixir also runnable on a system with SELinux, like the testcontainers implementation for Java?
What other information do I need to provide here, that this issue can be resolved?
Edit / Add:
- I am using docker-ce and not postman (so, I guess this is not in relation to this issue - or maybe it is, because there's also a mention of
SELinux?)...
- Having compared this repository with the testcontainers-dotnet one (because the other related issue I referenced here), I can see as difference that
testcontainers-dotnet actually uses the ryuk.container.privileged value from ~/.testcontainers.properties and also respects the environment variable TESTCONTAINERS_RYUK_CONTAINER_PRIVILEGED - there's no mention of these attributes within this repository... (but also not quite sure if this is an indication of why this is not working for me, because testcontainers-java works without such a config)
