Adding a compute host

Use the following procedure to add a compute host to an operational cluster.

1. Configure the host as a target host. See Chapter 4, *Target hosts* for more information.

2. Edit the /etc/openstack_deploy/openstack_user_config.yml file and add the host to the compute_hosts stanza.

   If necessary, also modify the used_ips stanza.

3. Run the following commands to add the host. Replace NEW_HOST_NAME with the name of the new host.

   $ cd /opt/openstack-ansible/playbooks
   $ openstack-ansible setup-everything.yml \
   rsyslog-config.yml --limit NEW_HOST_NAME
