GoLang postgres testcontainers init script doesn't work
问题
我想要使用初始化脚本启动postgres容器。
request := testcontainers.ContainerRequest{Image: "postgres:14.1-alpine",Entrypoint: nil,Env: map[string]string{"POSTGRES_DB": "postgres","PGUSER": "postgres","POSTGRES_PASSWORD": "postgres",//"PGDATA": "postgres",},ExposedPorts: []string{"5432"},BindMounts: map[string]string{"/media/mihovelgod/Новый том1/GoProjects/microservices/sql/go-sql/resources/migrations": "/docker-entrypoint-initdb.d",},Name: "postgres",User: "postgres",WaitingFor: wait.ForLog("database system is ready to accept connections"),AutoRemove: true,}container, err = testcontainers.GenericContainer(test.CTX,testcontainers.GenericContainerRequest{ContainerRequest: request,Started: true,},)if err != nil {log.Panicln(err)}
我在log.Panicln(err)中得到了以下错误信息：
failed to create containerError response from daemoninvalid mount config for type "bind": bind source path does not exist: /docker-entrypoint-initdb.d
问题是它在docker-compose.yml中完美地工作。如何修复这个问题？
英文:
I want to start postgres container with init script.
request := testcontainers.ContainerRequest{Image: "postgres:14.1-alpine",Entrypoint: nil,Env: map[string]string{"POSTGRES_DB": "postgres","PGUSER": "postgres","POSTGRES_PASSWORD": "postgres",//"PGDATA": "postgres",},ExposedPorts: []string{"5432"},BindMounts: map[string]string{"/media/mihovelgod/Новый том1/GoProjects/microservices/sql/go-sql/resources/migrations": "/docker-entrypoint-initdb.d",},Name: "postgres",User: "postgres",WaitingFor: wait.ForLog("database system is ready to accept connections"),AutoRemove: true,}container, err = testcontainers.GenericContainer(test.CTX,testcontainers.GenericContainerRequest{ContainerRequest: request,Started: true,},)if err != nil {log.Panicln(err)}
I got the following panic messages in log.Panicln(err):
failed to create containerError response from daemoninvalid mount config for type "bind": bind source path does not exist: /docker-entrypoint-initdb.d
The point is that it perfectly works from docker-compose.yml.
How to fix this?

看起来，根据源代码，TestContainers希望在BindMounts中使用container_path: host_path的形式。如果你尝试以下代码会发生什么：
BindMounts: map[string]string{"/docker-entrypoint-initdb.d": "/media/mihovelgod/Новый том1/GoProjects/microservices/sql/go-sql/resources/migrations",},
看起来，TestContainers的更新版本已经完全移除了BindMounts，并用一个更通用的Mounts字段来替代。
英文:
Looking at the source, it appears that TestContainers wants container_path: host_path in BindMounts. What happens if you try:
BindMounts: map[string]string{"/docker-entrypoint-initdb.d": "/media/mihovelgod/Новый том1/GoProjects/microservices/sql/go-sql/resources/migrations",},
It looks like more recent versions of TestContainers have removed BindMounts completely and replaced it with a more generic Mounts field.
