Chapter 8. Initiating overcloud deployment
Deploy the overcloud after completing the initial configuration and customization of services.
8.1. Initiating overcloud deployment
Deploy the overcloud to implement the configuration of the Red Hat OpenStack Platform (RHOSP) environment.
Prerequisites
-
During undercloud installation, set
generate_service_certificate=falsein theundercloud.conffile. Otherwise, you must inject a trust anchor when you deploy the overcloud.
If you want to add Ceph Dashboard during your overcloud deployment, see Chapter 10, Adding the Red Hat Ceph Storage Dashboard to an overcloud deployment.
Procedure
Deploy the overcloud using the openstack overcloud deploy command. For a complete list of all command arguments, see openstack overcloud deploy in the Command line interface reference.
The following is an example usage of the command:
$ openstack overcloud deploy --templates -r /home/stack/templates/roles_data_custom.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/cephadm/cephadm.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/cephadm/ceph-mds.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/cinder-backup.yaml \ -e /home/stack/templates/storage-config.yaml \ -e /home/stack/templates/deployed-ceph.yaml \ -e /home/stack/templates/networks-deployed.yaml \ -e /home/stack/templates/deployed-metal.yaml \ -e /home/stack/templates/deployed-vips.yaml \ --ntp-server pool.ntp.org
The example command uses the following options:
--templates-
Creates the overcloud from the default heat template collection,
/usr/share/openstack-tripleo-heat-templates/.
-
Creates the overcloud from the default heat template collection,
-r /home/stack/templates/roles_data_custom.yaml- Specifies a customized roles definition file.
-e /usr/share/openstack-tripleo-heat-templates/environments/cephadm/cephadm.yaml- Sets the director to finalize the previously deployed Ceph Storage cluster. This environment file deploys RGW by default. It also creates pools, keys, and daemons. If you do not want to deploy RGW or object storage, see the options described in Section 5.5, “Deployment options for Red Hat OpenStack Platform object storage”
-e /usr/share/openstack-tripleo-heat-templates/environments/cephadm/ceph-mds.yaml- Enables the Ceph Metadata Server, as described in Section 5.3, “Enabling Ceph Metadata Server”.
-e /usr/share/openstack-tripleo-heat-templates/environments/cinder-backup.yaml-
Enables the Block Storage Backup service (
cinder-backup), as described in Section 5.6, “Configuring the Block Storage Backup Service to use Ceph”.
-
Enables the Block Storage Backup service (
-e /home/stack/templates/storage-config.yaml- Adds the environment file that contains your custom Ceph Storage configuration as described in Section 5.1, “Configuring a custom environment file”
-e /home/stack/templates/deployed-ceph.yaml-
Adds the environment file that contains your Ceph cluster settings, as output by the
openstack overcloud ceph deploycommand run earlier.
-
Adds the environment file that contains your Ceph cluster settings, as output by the
-e /home/stack/templates/networks-deployed.yaml-
Adds the environment file that contains your Ceph cluster network settings, as output by
openstack overcloud network provision.
-
Adds the environment file that contains your Ceph cluster network settings, as output by
-e /home/stack/templates/deployed-metal.yaml-
Adds the environment file that contains your Ceph cluster node settings, as output by
openstack overcloud node provision.
-
Adds the environment file that contains your Ceph cluster node settings, as output by
-e /home/stack/templates/deployed-vips.yaml-
Adds the environment file that contains your Ceph cluster network VIP settings, as output by
openstack overcloud network vip provision.
-
Adds the environment file that contains your Ceph cluster network VIP settings, as output by
--ntp-server pool.ntp.org- Sets the NTP server.
