What happened?

I'm getting this error DOCKER_HOST unix:///var/run/docker.sock is not listening whenever I try to run the tests. I can run normal docker commands like docker ps and docker-compose up without any issue. I also checked /var/run/docker.sock and it exists:

ls -la /var/run/ | grep docker
srw-rw----  1 root     docker        0 лис 11 10:03 docker.sock

Can you try the following commands?

• check connectivity via docker.sock: curl --unix /var/run/docker.sock http://localhost/_ping
• show the active Docker Context: docker context ls

Thanks a lot @gesellix Those commands helped a lot 👍

[gesellix]

I'm curious, can you tell a bit more what the issue was?

[sergeda]

@gesellix Turn out that my docker.sock located not in the /var/run/docker.sock but in my home folder for some reason. I pointed testcontainers to that file and this error gone. Thank you

[gesellix]

Thanks @sergeda. So this looks indeed like the issues at #6076 and docker/for-mac#6529.
