What happened?

Anytime i try to use Testcontainers - I get the error message
System.ArgumentException
Docker is either not running or misconfigured. Please ensure that Docker is running and that the endpoint is properly configured. You can customize your configuration using either the environment variables or the ~/.testcontainers.properties file. For more information, visit:
https://dotnet.testcontainers.org/custom_configuration/ (Parameter 'DockerEndpointAuthConfig')

Relevant log output

No response

Additional information

Fluent Docker seems to work fine - Rider connects as well if I force the path unix://$HOME/.rd/docker.sock
I tried setting Environment Variables as well - and am probably just missing something.

Hi, can you try the configuration from Testcontainers for Java docs?

❯ export TESTCONTAINERS_HOST_OVERRIDE=$(rdctl shell ip a show rd0 | awk '/inet / {sub("/.*",""); print $2}')

ip: can't find device 'rd0'
