Mounting a SMB/CIFS File share for Docker in Nomad

Enable the Docker volume in your client config:

plugin "docker" {
  config {
    volumes {
      enabled = true
    }
  }
}

Below is a job to dynamically create a CIFS Docker volume and mount it to a container:

job "cifs-example" {
  datacenters = ["dc1"]

  group "cache" {
    network {
      port "db" {
        to = 6379
      }
    }

   task "redis" {
     driver = "docker"
     config {
        image = "redis:3.2"
        ports = ["db"]
        mounts {
            target = "/mount"
            source = "myRedisCIFS"
            volume_options {
              no_copy = "false"
              driver_config  {
        name = "local"
                options {
                type = "cifs"
                device = "//192.168.1.123/Nomad"
                o = "vers=3.0,dir_mode=0777,file_mode=0777,serverino,username=username,password=password"
                }
              }
            }
        }
      }

      resources {
        cpu    = 500
        memory = 256
      }
    }
  }
}

Please note that this job does not include any "cleanup" tasks (i.e. unmounting the volume) - it simply reproduces your original steps. However, we recommend that you include that logic if possible.
