testcontainers: how to fix bind source path does not exist

问题

我正在尝试使用testcontainers运行一个容器。这是我的代码:

func createContainer(ctx context.Context) (testcontainers.Container, *gorm.DB, string, error) {
	var env = map[string]string{
		"POSTGRES_PASSWORD": DbPass,
		"POSTGRES_USER":     DbUser,
		"POSTGRES_DB":       DbName,
	}
	var port = "5432/tcp"

	path := `C:/Desktop/Folder/golang/TgBotReminder/internal/db/postgresql/migration/notes.sql`

	req := testcontainers.GenericContainerRequest{
		ContainerRequest: testcontainers.ContainerRequest{
			Image:        "postgres:latest",
			ExposedPorts: []string{port},
			Env:          env,
			WaitingFor:   wait.ForLog("database system is ready to accept connections"),
			SkipReaper:   true,
			Mounts: testcontainers.Mounts(
				testcontainers.BindMount(path, "/docker-entrypoint-initdb.d"),
			),
		},
		Started: true,
	}
...

我在路径变量中提到的目录是存在的。但是我得到了错误:Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /pipe/docker_engine: creating reaper failed: failed to create container。即使我注释掉了带有Mounts的行,我仍然会得到这个错误。如何修复它?另外,在路径变量中输入文件名("notes.sql")是否正确?还是只需要在这里输入目录?

谢谢你的帮助。

我刚刚尝试了这段代码:

container, err := tspostgres.RunContainer(ctx,
		testcontainers.WithImage("postgres:latest"),
		tspostgres.WithInitScripts(filepath.Join(".", "test_migration", "notes.sql")),
		tspostgres.WithDatabase("test-db"),
		tspostgres.WithUsername("postgres"),
		tspostgres.WithPassword("postgres"),
		testcontainers.WithWaitStrategy(
			wait.ForLog("database system is ready to accept connections").
				WithOccurrence(2).WithStartupTimeout(5*time.Second)),
	)

	if err != nil {
		log.Fatal(err)
	}

得到了相同的错误。

这是我尝试的另一段代码:

path := `/${PWD}/desktop/folder/golang/tgbotreminder/internal/db/postgresql/migration/notes.sql`
target := "/docker-entrypoint-initdb.d/"
...
Mounts: testcontainers.ContainerMounts{
				testcontainers.ContainerMount{
					Source: testcontainers.GenericBindMountSource{
						HostPath: path,
					},
					Target: testcontainers.ContainerMountTarget(target),
				},
			},

还是没有成功 testcontainers:如何修复绑定源路径不存在的问题

这是我另一次尝试的代码:

Mounts: testcontainers.Mounts(testcontainers.ContainerMount{
                Source: testcontainers.GenericBindMountSource{
                        HostPath: path,
                },
                Target: testcontainers.ContainerMountTarget(target),
        }),

它也不起作用。

英文:

I'm trying to run a container using testcontainers. Here is my code:

func createContainer(ctx context.Context) (testcontainers.Container, *gorm.DB, string, error) {
	var env = map[string]string{
		"POSTGRES_PASSWORD": DbPass,
		"POSTGRES_USER":     DbUser,
		"POSTGRES_DB":       DbName,
	}
	var port = "5432/tcp"

	path := `C:/Desktop/Folder/golang/TgBotReminder/internal/db/postgresql/migration/notes.sql`

	req := testcontainers.GenericContainerRequest{
		ContainerRequest: testcontainers.ContainerRequest{
			Image:        "postgres:latest",
			ExposedPorts: []string{port},
			Env:          env,
			WaitingFor:   wait.ForLog("database system is ready to accept connections"),
			SkipReaper:   true,
			Mounts: testcontainers.Mounts(
				testcontainers.BindMount(path, "/docker-entrypoint-initdb.d"),
			),
		},
		Started: true,
	}
...

The directory I've mentioned in the path variable exists. But I got the error: Error response from daemon: invalid mount config for type "bind": bind source path does not exist: /pipe/docker_engine: creating reaper failed: failed to create container.
I got this error even if I comment lines with Mounts.
How to fix it? And also is it correct to type filename in the path variable ("notes.sql")? Or should I only type the directory here?

Thank you in advance

Update 1

I also tried this code right now:

container, err := tspostgres.RunContainer(ctx,
		testcontainers.WithImage("postgres:latest"),
		tspostgres.WithInitScripts(filepath.Join(".", "test_migration", "notes.sql")),
		tspostgres.WithDatabase("test-db"),
		tspostgres.WithUsername("postgres"),
		tspostgres.WithPassword("postgres"),
		testcontainers.WithWaitStrategy(
			wait.ForLog("database system is ready to accept connections").
				WithOccurrence(2).WithStartupTimeout(5*time.Second)),
	)

	if err != nil {
		log.Fatal(err)
	}

got the same error

Update 2

Here is another piece of code I've tried:

path := `/${PWD}/desktop/folder/golang/tgbotreminder/internal/db/postgresql/migration/notes.sql`
target := "/docker-entrypoint-initdb.d/"
...
Mounts: testcontainers.ContainerMounts{
				testcontainers.ContainerMount{
					Source: testcontainers.GenericBindMountSource{
						HostPath: path,
					},
					Target: testcontainers.ContainerMountTarget(target),
				},
			},

No luck again testcontainers:如何修复绑定源路径不存在的问题

Update 3

Here is my another attempt:

Mounts: testcontainers.Mounts(testcontainers.ContainerMount{
                Source: testcontainers.GenericBindMountSource{
                        HostPath: path,
                },
                Target: testcontainers.ContainerMountTarget(target),
        }),

It also doesn't work

似乎问题出在图像Ryuk和一些硬编码的值上,这些值与Windows不兼容。

testcontainers-go目前不支持“Windows容器”:它有一些硬编码的默认值,没有考虑到Windows容器的可能性。

请参考https://github.com/testcontainers/testcontainers-go/issues/948

英文:

It seems like the issue is with the image Ryuk and some hard-coded values which is not compatible with windows.
> testcontainers-go currently doesn't support "Windows containers": it has some hard-coded defaults that don't consider the possibility of Windows containers.

我在我的机器上遇到了相同的问题。完整的错误消息如下:

2023/07/11 12:15:35 github.com/testcontainers/testcontainers-go - 连接到docker:
  服务器版本:20.10.14
  API版本:1.41

panic: 守护程序的错误响应:类型为"bind"的挂载配置无效:绑定源路径不存在:/pipe/docker_engine:创建reaper失败:无法创建容器

正如@pratheesh-pc指出的那样,这意味着无法从镜像docker.io/testcontainers/ryuk:0.5.1创建容器。这与您要创建的自己容器的挂载配置无关。我认为@pratheesh-pc回答中提供的链接是针对Windows上的Windows容器(WCOW),但我在运行Windows上的Linux容器(LCOW)时遇到了这个问题。

一个解决方法是禁用reaper。实际上,您在代码中设置了SkipReaper: true,并且您的意图是禁用reaper。问题是,从github.com/testcontainers/testcontainers-go@v0.20.0开始,SkipReaper被完全忽略了,您必须使用以下方法之一来禁用它:the following approaches

  1. .testcontainers.properties文件中添加ryuk.disabled=true。在Windows上,文件的完整路径是C:/Users/%my_username%/.testcontainers.properties
  2. 设置TESTCONTAINERS_RYUK_DISABLED=true环境变量。此方式优先于属性文件。
英文:

I have encountered the same issue on my machine. The full error message is:

2023/07/11 12:15:35 github.com/testcontainers/testcontainers-go - Connected to docker:

As pointed out by @pratheesh-pc, It means that it failed to create the container from the image docker.io/testcontainers/ryuk:0.5.1. It has nothing to do with the mounts configuration of your own container that you want to create. I think the link provided in @pratheesh-pc's answer is for Windows Container on Windows (WCOW), but I encountered the issue when running Linux Container on Windows (LCOW).

A workaround is to disable the reaper. In fact, you have set SkipReaper: true in your code and you meant to disable the reaper. The problem is, from github.com/testcontainers/testcontainers-go@v0.20.0, SkipReaper is totally ignored, and you have to disable it with one of the following approaches:

  1. adding ryuk.disabled=true to the .testcontainers.properties file. On Windows, the full path of the file is C:/Users/%my_username%/.testcontainers.properties.
  2. setting the TESTCONTAINERS_RYUK_DISABLED=true environment variable. This manner takes precedence over the properties file.

似乎问题出在 Mounts 部分,请尝试:

Mounts: []testcontainers.Mount{
    {
        Source: path,
        Target: "/docker-entrypoint-initdb.d/notes.sql",
        Type:   testcontainers.BindMountType,
    },
},

在指定绑定挂载的源路径时,应提供完整的文件路径,包括文件名本身。因此,在路径变量中包含文件名("notes.sql")是正确的。

英文:

it seems like the issue lies with the Mounts try:

Mounts: []testcontainers.Mount{
            {
                Source: path,
                Target: "/docker-entrypoint-initdb.d/notes.sql",
                Type:   testcontainers.BindMountType,
            },
        },

when specifying the source path for a bind mount, you should provide the complete path to the file, including the file name itself. So, it is correct to include the filename ("notes.sql") in the path variable.

已解决

C:/Users/%my_username%/目录下创建了一个名为.testcontainers.properties的文件,并在其中写入了ryuk.disabled=true

英文:

Solved

created a file .testcontainers.properties in the C:/Users/%my_username%/ and wrote there: ryuk.disabled=true
