2. Your client should still be pointing to Docker Engine on `manager`. Use the following syntax to run a Swarm container as the primary Swarm manager on `manager`.
$ docker run -d -p <your_selected_port>:2375 -t swarm manage token://<cluster_id> >
$ docker run -d -p <your_selected_port>:3376 -t -v /var/lib/boot2docker:/certs:ro swarm manage -H 0.0.0.0:3376 --tlsverify --tlscacert=/certs/ca.pem --tlscert=/certs/server.pem --tlskey=/certs/server-key.pm token://<cluster_id>
For example:
$ docker run -d -p 2375:2375 -t swarm manage token://0ac50ef75c9739f5bfeeaf00503d4e6e
$ docker run -d -p 3376:3376 -t -v /var/lib/boot2docker:/certs:ro swarm manage -H 0.0.0.0:3376 --tlsverify --tlscacert=/certs/ca.pem --tlscert=/certs/server.pem --tlskey=/certs/server-key.pm swarm manage token://0ac50ef75c9739f5bfeeaf00503d4e6e
The -p option maps a port on the container to a port on the host.
The `-p` option maps a port 3376 on the container to port 3376 on the host. The `-v` option mounts the directory containing TLS certificates (`/var/lib/boot2docker` for the `manager` VM) into the container running Swarm manager in read-only mode.

## Manage your Swarm
Here, you connect to the cluster and review information about the Swarm manager and nodes. You tell the Swarm run a container and check which node did the work.

1. Connect the Docker Client to the Swarm.
1. Connect the Docker Client to the Swarm by updating the `DOCKER_HOST` environment variable.
$ eval $(docker-machine env swarm)
$ DOCKER_HOST=<manager_ip>:<your_selected_port>
Because Docker Swarm uses the standard Docker API, you can connect to it using Docker Client and other tools such as Docker Compose, Dokku, Jenkins, and Krane, among others.
For the current example, the `manager` has IP address `192.168.99.100` and we selected port 3376 for the Swarm manager.
$ DOCKER_HOST=192.168.99.100:3376
