## Use Docker commands
To ensure that the docker stack commands are available on your installation, try
`docker stack ls`. If you see the message `failed to find a Stack API version`
then the commands described on this page are not available. This can be confirmed
with `docker version` which should contain the line `StackAPI: Unknown`.
If docker stack commands are working then you can deploy a stack on Kubernetes with
`docker stack deploy`, the `docker-compose.yml` file, and the name of the stack.
```bash
docker stack deploy --compose-file /path/to/docker-compose.yml mystack
docker stack services mystack
```
You can see the service deployed with the `kubectl get services` command.
### Specify a namespace
By default, the `default` namespace is used. You can specify a namespace with
the `--namespace` flag.
```bash
docker stack deploy --namespace my-app --compose-file /path/to/docker-compose.yml mystack
```
Run `kubectl get services -n my-app` to see only the services deployed in the
`my-app` namespace.
### Override the default orchestrator
While testing Kubernetes, you may want to deploy some workloads in swarm mode.
Use the `DOCKER_STACK_ORCHESTRATOR` variable to override the default orchestrator for
a given terminal session or a single Docker command. This variable can be unset
(the default, in which case Kubernetes is the orchestrator) or set to `swarm` or
`kubernetes`. The following command overrides the orchestrator for a single
deployment, by setting the variable{% if platform == "mac"" %}
at the start of the command itself.
```bash
DOCKER_STACK_ORCHESTRATOR=swarm docker stack deploy --compose-file /path/to/docker-compose.yml mystack
```{% elsif platform == "windows" %}
before running the command.
```shell
set DOCKER_STACK_ORCHESTRATOR=swarm
docker stack deploy --compose-file /path/to/docker-compose.yml mystack
```
{% endif %}
Alternatively, the `--orchestrator` flag may be set to `swarm` or `kubernetes`
when deploying to override the default orchestrator for that deployment.
```bash
docker stack deploy --orchestrator swarm --compose-file /path/to/docker-compose.yml mystack
```

## Example app
Docker has created the following demo app that you can deploy to swarm mode or
to Kubernetes using the `docker stack deploy` command.
```yaml
version: "{{ site.compose_file_v3 }}"
services:
web:
image: dockersamples/k8s-wordsmith-web
ports:
- "80:80"
words:
image: dockersamples/k8s-wordsmith-api
deploy:
replicas: 5
endpoint_mode: dnsrr
resources:
limits:
memory: 50M
reservations:
memory: 50M
db:
image: dockersamples/k8s-wordsmith-db
```
If you already have a Kubernetes YAML file, you can deploy it using the
`kubectl` command.
