Define the mount point of the volume in GoLangDockerSDK-1024programmer

I’m currently trying to create a Docker container using the official GoLang Docker SDK and trying to mount a volume from my localhost to the Docker container.

vol := map[string]struct{}{"/pathInDocker":{}}

 // This was prepared using example at:
 //https://docs.docker.com/develop/sdk/examples/#run-a-container
 res, err := cli.ContainerCreate(ctx, &container.Config{
     Image: testImageName,
     Volumes: vol,
     Cmd: []string{"ls", "/"},
 }, nil, nil, "")

This works when I create the container and add “/pathInDocker” to the docker container, however, I can’t figure out how to add a mount point for localhost.

I have tried the following possible values for the vol variable

vol := map[string]struct{}{"localPath:/pathInDocker":{}}
 vol := map[string]struct{}{"\"localPath\":\"/pathInDocker\"":{}}

For each of these, the final docker container attempts to mount the map key as a folder within docker, without a mount point for localhost.

I’ve looked through the documentation and the only thing I can seem to find about how to configure volumes is:

Volumes map[string]struct{} // List of volumes (mounts) used for the container

So my question is how do I configure it so that a local folder is mounted to that volume?

If you want to use bind installation, you need to provide the installation in HostConfig information.

res, err := client.ContainerCreate(
     ctx,
     &container.Config{
         Image: "nginx",
         Cmd: []string{"ls", "/"},
     },
     &container.HostConfig{
         Mounts: []mount.Mount{
             {
                 Type: mount.TypeBind,
                 Source: "/localPath",
                 Target: "/pathInDocker",
             },
         },
     },
     nil,
     "",
 )

Also, if you want to use volumes, you first need to create the volume with the mount path, and then you need to use this volume name as the “source”.

I can mount it by first creating a docker volume using `VolumeCreate`, then using the name of my volume in the mount array like @aerokite: `myMount:= mount.Mount {Type: volume.TypeVolume source: myVolume .Name target: “/var/lib/postgresql/data”}`
