Additional Information

I set the env. variables as it was suggested and it didn't help to resolve this problem. This issue doesn't happen when I run tests against the docker desktop.

Perhaps I should modify this file ~/.testcontainers.properties?

Hi, Did you check the docs?

Hi, Did you check the docs?

Yep, didn't help.

Can you provide more information, please? Can you enable logs and share them? See https://java.testcontainers.org/features/container_logs/

Also, I think the value is export DOCKER_HOST=unix://${HOME}/.colima/default/docker.sock

The logs are in the issue. The test containers fail during the initialization. In order to reproduce this problem these steps are sufficient

1. Use Dynolite module
2. Install the latest version of Colima and Docker
3. Create the minimal test that uses the Dynolite module

[eddumelendez]

The reason why I'm asking about more information is because I think this is related to your environment and not specific to Testcontainers. I'm able to run the test with Colima. I've moved it to Discussion instead.

[tarasmurzenkovv]

1. Could you provide the versions of the colima and docker?
2. Did you manage to run the test using thy Dynolite module?
