    10  # Docker (External) App Type
    11  
    12  **Type:** `docker-external`
    13  
    14  The "docker-external" application type is used for Docker images
    15  that are already built and in a registry somewhere. The "external" is
    16  there to signify that the image is built external to the Otto lifecycle,
    17  and already exists.
    18  
    19  The primary purpose of this application type is to make it incredibly
    20  easy to depend and deploy anything in the Docker ecosystem with Otto.
    21  
    22  ## Example
    23  
    24  Below is an example Appfile that uses the "docker-external" type:
    25  
    26  ```
    27  application {
    28      name = "mongodb"
    29      type = "docker-external"
    30  }
    31  
    32  customization "docker" {
    33      image = "mongo:3.0"
    34      run_args = "-p 27017:27017"
    35  }
    36  ```
    37  
    38  This Appfile can be used as a dependency of another application, and
    39  can be deployed as well.
