I want to run my integration test on my mac m1 which has colima but I'm getting an error

I set env variables according to this article https://www.rockyourcode.com/testcontainers-with-colima/ but it doesn't help.
Does anybody know how to run testcontainers with colima?

Fails pretty early, can you run following example? Does it response with the version?

using var dockerClientConfiguration = TestcontainersSettings.OS.DockerEndpointAuthConfig.GetDockerClientConfiguration();
using var dockerClient = dockerClientConfiguration.CreateClient();

var version = await dockerClient.System.GetVersionAsync()
  .ConfigureAwait(false);

Is Colima running correct? Can you share your test configuration? I've installed Colima and it runs a simple test just fine (you may have to disable the Resource Reaper TESTCONTAINERS_RYUK_DISABLED=true).

Colima is running fine:

INFO[0000] runtime: docker
INFO[0000] mountType: sshfs

DockerClient which is sending request has

_enpointBaseUrl = http://docker.sock/
Configuration.EndpointBaseUrl = unix:/var/run/docker.sock

My env variables

DOCKER_HOST=unix:////Users/cybul26/.colima/docker.sock
TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE=/Users/cybul26/.colima/docker.sock
TESTCONTAINERS_RYUK_DISABLED=true

The DOCKER_HOST env variable is wrong (default directory) is missing. TESTCONTAINERS_DOCKER_SOCKET_OVERRIDE not yet supported in Testcontainers for .NET.

Had same thought but after adding default nothing changed. Turns out my environment variables are not loading during integration tests. After setting it manually

Environment.SetEnvironmentVariable("DOCKER_HOST", "unix:///Users/cybul26/.colima/docker.sock");

everything works fine and Environment.GetEnvironmentVariable("DOCKER_HOST") returns correct host instead null.
I'm using Rider and my bet is that they screwed something with Test Runner in a new version of Rider.
After setting environment variables in test runner in Rider, everything works as expected.

Thanks for help and by the way you are doing great job with this project. Thank you!

After setting environment variables in test runner in Rider, everything works as expected.

👍 That is what I did too. I added the environment variable in Preferences | Build, Execution, Deployment | Unit Testing | Test Runner.

I had some issues with setting up colima as well, so I'd like to share the steps I took to fix it for other people having issues with this. I migrated from docker desktop.

I did set the DOCKER_HOST env variable and on startup testcontainers did output the expected endpoint (unix:///Users/<user>/.colima/default/docker.sock). But I still ran into this error:

Error Message:
   System.AggregateException : One or more errors occurred. (Object reference not set to an instance of an object.) (Object reference not set to an instance of an object.)
---- System.NullReferenceException : Object reference not set to an instance of an object.
---- System.NullReferenceException : Object reference not set to an instance of an object.
  Stack Trace:
  
----- Inner Stack Trace #1 (System.NullReferenceException) -----
   at DotNet.Testcontainers.Containers.DockerContainer.get_State()
   at DotNet.Testcontainers.Configurations.UntilContainerIsRunning.UntilAsync(IContainer container)
   at DotNet.Testcontainers.Containers.DockerContainer.<>c__DisplayClass60_0.<<UnsafeStartAsync>g__CheckWaitStrategyAsync|1>d.MoveNext()
--- End of stack trace from previous location ---
...

Eventually I tried removing the existing symlink at /var/run/docker.sock and symlinking the colima endpoint:
sudo ln -s /Users/$USER/.colima/docker.sock /var/run/docker.sock

I also removed the DOCKER_HOST env var. This fixed that exception. (Solution taken from this GitHub issue).

I then got some inexplicable connection refused errors:

  Error Message:
   Npgsql.NpgsqlException : Failed to connect to 127.0.0.1:32810
---- System.Net.Sockets.SocketException : Connection refused

This is apparently due to colima not immediately binding ports to the host IP. So my (slightly ugly) solution for this was adding a startup callback delay to my container builder:

    public readonly PostgreSqlContainer PostgreSqlContainer = new PostgreSqlBuilder()
        .WithImage("postgres:15")
        .WithDatabase("Test")
        .WithUsername("testcontainers")
        .WithPassword("testcontainers")
        .WithStartupCallback((_, _) => Task.Delay(3000))
        .Build();

3 seconds seems to be the sweet spot. Also got this troubleshooting step from the GitHub issue in the colima repo.

After this, it works as expected :)
