Setup for voting app example	multi-container, services, swarm mode, cluster, voting app, docker-stack.yml, docker stack deploy	Deploy the application

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

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 onto the manager node.

    $ docker-machine ssh manager
   

4. Check to make sure the .yml file is there.

    docker@manager:~$ ls
    docker-stack.yml  log.log
   

You can use vi or other text editor to inspect it.

Deploy the app

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

    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 <appName>.

    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. We will vote for cats and dogs, view the results, and monitor the manager and worker nodes, containers and services on a visualizer.
