|
|
|
|
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
|
|

## 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).
