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 "example" {
  datacenters = ["dc1"]
  group "cache" {
    task "redis" {
      driver = "docker"
      config {
        image = "redis:3.2"
        port_map { db = 6379 }
        mounts = [
          {
            target = "/mount"
            source = "myRedisCIFS"
            volume_options {
              no_copy = false
              driver_config {
                name = "local"
                options = {
                  type = "cifs"
                  device = "//10.171.88.201/azu-share"
                  o = "vers=3.0,dir_mode=0777,file_mode=0777,serverino,username=STORAGE_USERNAME,password=XXXX"
                }
              }
            }
          }
        ]
      }
      resources { network { port "db" {} } }
      service {
        port = "db"
        check {
          name = "alive"
          type = "tcp"
          interval = "10s"
          timeout = "2s"
        }
      }
    }
  }
}

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.
