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 3, *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. If the cluster is utilizing Ceilometer, it will be necessary to edit the /etc/openstack_deploy/conf.d/ceilometer.yml file and add the host to the metering-compute_hosts stanza.

  4. 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-hosts.yml --limit NEW_HOST_NAME
# openstack-ansible setup-openstack.yml --skip-tags nova-key-distribute --limit NEW_HOST_NAME
# openstack-ansible setup-openstack.yml --tags nova-key --limit compute_hosts
