Starting the Middleware Manager Services

Start the mwmanager-services and link it to the running Cassandra instance. By default the middleware manager container will create a volume under /var/opt/hawkular/data. As with the Cassandra container, you can use the -v option to map the middleware manager data volume to a specific host directory.

Note
The Z option is necessary on Red Hat Enterprise Linux/Fedora based systems to correctly set the SELinux permissions.
```
docker run -d --link=mwmanager-cassandra \
-e CASSANDRA_NODES=mwmanager-cassandra \
-e HAWKULAR_BACKEND=remote \
-p 8080:8080 -p 8443:8443 -p 9990:9990 \
-v /var/opt/mwmanager-data:/var/opt/hawkular/data:Z registry.access.redhat.com/jboss-mm-7-tech-preview/middleware-manager:latest
```

Run the Middleware Manager container and tell it to connect to Cassandra. If desired, you can specify a combination of username/password for HAWKULAR_USERNAME and HAWKULAR_PASSWORD. If you do not specify a user name and password, one will be automatically generated when you start the container.

docker run --name mwmanager  -d \
          -e HAWKULAR_BACKEND=remote   \
          -e CASSANDRA_NODES=mwmanager-cassandra \
          -e HAWKULAR_USE_SSL=true \
          -e HAWKULAR_USERNAME=my_mwmanager_username \
          -e HAWKULAR_PASSWORD=my_mwmanager_password \
          -p 8080:8080 -p 8443:8443 -p 9990:9990 \
          --link=mwmanager-cassandra \
          registry.access.redhat.com/jboss-mm-7-tech-preview/middleware-manager:latest
