What happened?

I'm trying to run gradle java spring app with testcontainers in containerd container but I'm getting the following error:

ERROR org.testcontainers.dockerclient.DockerClientProviderStrategy -- Could not find a valid Docker environment. Please check configuration. Attempted configurations were:
          UnixSocketClientProviderStrategy: failed with exception InvalidConfigurationException (Could not find unix domain socket). Root cause NoSuchFileException (/var/run/docker.sock)
          DockerDesktopClientProviderStrategy: failed with exception NullPointerException (Cannot invoke "java.nio.file.Path.toString()" because the return value of "org.testcontainers.dockerclient.DockerDesktopClientProviderStrategy.getSocketPath()" is null)As no valid configuration was found, execution cannot continue.

This is because containerd does not support docker socket and there really is no file there. Could you tell me, is there any workaround for this? couldn't find the configuration setting for containerd in the documentation

Relevant log output

Despite having in my docker-compose.yml:

volumes:
      - $PWD:$PWD
      - $HOME/.docker/run/docker.sock:/var/run/docker.sock

I also tried:

- /var/run/docker.sock:/var/run/docker.sock

I struck with the same issue:
