|
The voting app will continue to run on the swarm while the `manager` and `worker` machines are running, unless you explicitly stop it.
|
|
|
|
## Stopping the voting app
|
|
|
|
To shut down the voting app, simply stop the machines on which it is running. If you are using local hosts, follow the steps below. If you are using cloud hosts, stop them per your cloud setup.
|
|
|
|
1. Open a terminal window and run `docker-machine ls` to list the current machines.
|
|
|
|
```
|
|
$ docker-machine ls
|
|
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
|
|
manager - virtualbox Running tcp://192.168.99.100:2376 v1.13.1
|
|
worker - virtualbox Running tcp://192.168.99.101:2376 v1.13.1
|
|
```
|
|
2. Use `docker-machine stop` to shut down each machine, beginning with the worker.
|
|
|
|
```
|
|
$ docker-machine stop worker
|
|
Stopping "worker"...
|
|
Machine "worker" was stopped.
|
|
|
|
$ docker-machine stop manager
|
|
Stopping "manager"...
|
|
Machine "manager" was stopped.
|
|
```
|
|
|
|
## Restarting the voting app
|
|
|
|
If you want to come back to your `manager` and `worker` machines later, you can
|
|
keep them around. One advantage of this is that you can simply restart the
|
|
machines to launch the sample voting app again.
|
|
|
|
To restart local machines, follow the steps below. To restart cloud instances,
|
|
start them per your cloud setup.
|
|
|
|
1. Open a terminal window and list the machines.
|
|
|
|
```
|
|
$ docker-machine ls
|
|
NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS
|
|
manager - virtualbox Stopped Unknown
|
|
worker - virtualbox Stopped Unknown
|
|
```
|
|
|
|
3. Run `docker-machine start` to start each machine, beginning with the manager.
|
|
|
|
```
|
|
$ docker-machine start manager
|
|
Starting "manager"...
|
|
(manager) Check network to re-create if needed...
|
|
(manager) Waiting for an IP...
|
|
Machine "manager" was started.
|
|
Waiting for SSH to be available...
|
|
Detecting the provisioner...
|
|
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.
|
|
|
|
$ docker-machine start worker
|
|
Starting "worker"...
|
|
(worker) Check network to re-create if needed...
|
|
(worker) Waiting for an IP...
|
|
Machine "worker" was started.
|
|
Waiting for SSH to be available...
|
|
Detecting the provisioner...
|
|
Started machines may have new IP addresses. You may need to re-run the `docker-machine env` command.
|
|
```
|
|
|
|
3. Run the following commands to log into the manager and see if the swarm is up.
|
|
|
|
```
|
|
docker-machine ssh manager
|
|
|
|
docker@manager:~$ docker stack services vote
|
|

|

|
|

|
|
x5wcvknlnnh7 vote_result replicated 1/1 dockersamples/examplevotingapp_result:after
|
|
```
|
|
|
|
At this point, the app is back up. The web pages you looked at in the [test drive](test-drive.md) should be available, and you could experiment, modify the app, and [redeploy](customize-app.md).
|
|
|
|
## Removing the machines
|
|
|
|
If you prefer to remove your local machines altogether, use `docker-machine rm`
|
|
to do so. (Or, `docker-machine rm -f` will force-remove running machines.)
|
|
|
|
```
|
|
$ docker-machine rm worker
|
|
About to remove worker
|
|
WARNING: This action will delete both local reference and remote instance.
|
|
Are you sure? (y/n): y
|
|
Successfully removed worker
|
|
|
|
$ docker-machine rm manager
|
|
About to remove manager
|
|
WARNING: This action will delete both local reference and remote instance.
|
|
Are you sure? (y/n): y
|
|
Successfully removed manager
|
|
```
|
|
|
|
The Docker images you pulled were all running on the virtual machines you
|
|
created (either local or cloud), so no other cleanup of images or processes is
|
|
needed once you stop and/or remove the virtual machines.
|
|
|
