如何在启动xunit测试之前调出docker compose中指定的容器?

要在没有任何额外依赖项的情况下执行此操作,可以使用 Process.Start 通过命令行模拟启动。以下是包装并提供此功能的类:

public class DockerStarter : IDisposable
{
    private const string DOCKER_COMPOSE = @"c:\Program Files\Docker\Docker\resources\bin\docker-compose.exe";
    public string ComposeFile { get; set; }
    public string WorkingDir { get; set; }

    public DockerStarter(string composeFile, string workingDir)
    {
        ComposeFile = composeFile;
        WorkingDir = workingDir;
    }

    public void Start()
    {
        var startInfo = generateInfo("up");
        _dockerProcess = Process.Start(startInfo);
        // TODO: Find better way to wait for Docker containers to start
        Thread.Sleep(1000);
    }

    private Process _dockerProcess;

    public void Dispose()
    {
        _dockerProcess.Close();

        var stopInfo = generateInfo("down");
        var stop = Process.Start(stopInfo);
        stop.WaitForExit();
    }

    private ProcessStartInfo generateInfo(string argument)
    {
        var procInfo = new ProcessStartInfo
        {
            FileName = DOCKER_COMPOSE,
            Arguments = $"-f {ComposeFile} {argument}",
            WorkingDirectory = WorkingDir
        };
        return procInfo;
    }
}

显然,这种方法有缺点:

• 固定路径到 docker-compose 可执行文件
• 手动等待容器启动

我会看看是否有更好的方式直接与Docker守护进程交互,并在可能的情况下更新答案。
