title: Deploy the application

In these steps, you'll use the `docker-stack.yml` file to
deploy the voting application to the swarm you just created.

## Copy docker-stack.yml to the manager

The `docker-stack.yml` file must be located on a manager for the swarm where you want to deploy the application stack.

1.  Get `docker-stack.yml` either from the lab or by copying it from the example given here.

2.  Copy `docker-stack.yml` from your host machine onto the manager.

    ```
    $ docker-machine scp ~/sandbox/voting-app/docker-stack.yml manager:/home/docker/.
    docker-stack.yml                                                                      100% 1558     1.5KB/s   00:00
    ```

3.  Log into the manager node.

    ```
    $ docker-machine ssh manager
    ```

    The `ssh` login should put you in `/home/docker/` by default.

4.  Check to make sure that the `.yml` file is there, using `ls`.

    ```
    docker@manager:~$ ls /home/docker/
    docker-stack.yml
    ```

    You can use `vi` or `cat` to inspect the file.

## Deploy the app

We'll deploy the application from the manager.

1.  Deploy the application stack based on the `.yml` using the command `docker stack deploy` as follows.

    ```
    docker stack deploy --compose-file docker-stack.yml vote
    ```

    Here is an example of the command and the output.

    ```
    docker@manager:~$ docker stack deploy --compose-file docker-stack.yml vote
    Creating network vote_default
    Creating network vote_backend
    Creating network vote_frontend
    Creating service vote_result
    Creating service vote_worker
    Creating service vote_visualizer
    Creating service vote_redis
    Creating service vote_db
    Creating service vote_vote
    ```

2.  Verify that the stack deployed as expected with `docker stack services <APP-NAME>`.

    ```
    docker@manager:~$ docker stack services vote
    ID            NAME             MODE        REPLICAS  IMAGE
    0y3q6lgc0drn  vote_result      replicated  2/2       dockersamples/examplevotingapp_result:before
    fvsaqvuec4yw  vote_redis       replicated  2/2       redis:alpine
    igev2xk5s3zo  vote_worker      replicated  1/1       dockersamples/examplevotingapp_worker:latest
    vpfjr9b0qc01  vote_visualizer  replicated  1/1       dockersamples/visualizer:stable
    wctxjnwl22k4  vote_vote        replicated  2/2       dockersamples/examplevotingapp_vote:before
    zp0zyvgaguox  vote_db          replicated  1/1       postgres:9.4
    ```

## What's next?

In the next steps, we'll view components of the running app
on web pages, and [take the app for a test drive](test-drive.md).
