Running two Testcontainer Projects, randomly generate errors when using Ryuk

[edcastanohunter]

Hi, I am having two project using Testcontainers, I have configure images for postgres and redis within each test project with different ports. But what is happening when I run my solution within a pipeline, is that it starts to chrash. I may think that this is because we are trying to use Ryuk for both projects and It is causing the test run to fail within the pipeline. Not absolutely sure yet, but this is my first impression. I tried to see if the Ryuks port is configurable but it is not. Could you help me understand a little bit better this issue?

Error Message:

I may think that this is because we are trying to use Ryuk for both projects and It is causing the test run to fail within the pipeline.

I do not think that is the case, even multiple instances of Ryuk do not interfere with each other. Running multiple test projects works fine too, even in parallel.

Can you please share your Testcontainers configuration (tests)? This sounds like a misconfiguration of the container definition (builder).
