Ductus.FluentDocker.Common.FluentDockerException : Could not dispose composite service from file(s)

[enrico23]

I have some integration tests running on Docker using FluentDocker, version 2.10.59

I am using the NUnit lifecycle to create and destroy instances of a Test Environment.

You can see the implementation of the class 'TestEnvironment':

public sealed class SystemTestEnvironment
{
    private SystemTestEnvironment()
    {
        DockerHost = DockerHelpers.GetDockerHost();
        DockerComposeService = Build(DockerHost);
        try
        {
            DockerComposeService.Start();
        }
        catch(Exception ex)
        {
            Debug.WriteLine($"[Fluent Docker Error]: {ex} ");
            DockerComposeService.Dispose();
            throw;
        }
        OnContainerInitialized();
    }

	// ...  code removed  for simplicity

	public static void Initialize()
    {
        Instance = new SystemTestEnvironment();
    }

 		// ...  code removed  for simplicity
           
    
     private ICompositeService Build(IHostService dockerHost)
    {
        return new DockerComposeCompositeService(dockerHost, new DockerComposeConfig
        {
            ComposeFilePath = new List<string> { SqlServerComposeFile },
            ForceRecreate = true,
            RemoveOrphans = true,
            StopOnDispose = true,
            KeepVolumes = false
        });
    }
}

This is the method GetDockerHost

public static IHostService GetDockerHost()
    {
        var hosts = new Hosts().Discover();
        var defaultHost = hosts.FirstOrDefault(x => x.IsNative) ?? hosts.FirstOrDefault(x => x.Name == "default");
        var host = defaultHost ?? (hosts.Count > 0 ? hosts.First() : GetDockerHost());
        if (host.State is not ServiceRunningState.Running)
        {
            host.Start();
        }

        return host;
    }

I am getting the error when I am attempting

 DockerComposeService.Dispose();

The code was working previously on Azure DevOps and still works locally.

I use GitHub Actions and workflow for CI

The Github agent has the following Docker Tooling installed:
Docker version 20.10.24+azure-1
docker-compose version 1.29.2

Hi @enrico23 and thanks for the bug report. I do not have access to an azure environment. Have you tried to enable logging and see what commands being emitted and tried them manually. If not, please do and add the commands and which of them were erroneous (if any)?

Cheers,
Mario :)

Hi @mariotoffia.
Thanks for looking into it.

I found the issue!

I added the "project name" for the Docker Compose file to determine how it was displayed by Docker Desktop.

version: "3.8"
name: "sqltest1" ########### this line caused the issue ######
services:
    sql-server-db:
        hostname: sqltest1
        container_name: sqltest1-container

We're running into a similar item in our Ubuntu build environment. The environment has Docker Compose versions v1 1.29.2 and v2 2.23.3. It looks like docker-compose which is what FluentDocker uses points to v1, but our compose file is set up for v2.

We're currently adding a build step that aliases docker-compose to docker compose
