1.5. Deploying the HCI overcloud
You must deploy the overcloud after you complete the HCI configuration.
Do not enable Instance HA when you deploy a Red Hat OpenStack Platform (RHOSP) HCI environment. Contact your Red Hat representative if you want to use Instance HA with hyperconverged RHOSP deployments with Red Hat Ceph Storage.
Prerequisites
-
You are using a separate base environment file, or set of files, for all other Red Hat Ceph Storage settings, for example,
/home/stack/templates/storage-config.yaml. For more information, see Customizing the Storage service and Appendix A. Sample environment file: creating a Ceph Storage cluster. - You have defined the number of nodes you are assigning to each role in the base environment file. For more information, see Assigning nodes and flavors to roles.
-
During undercloud installation, you set
generate_service_certificate=falsein theundercloud.conffile. Otherwise, you must inject a trust anchor when you deploy the overcloud, as described in Enabling SSL/TLS on Overcloud Public Endpoints.
Procedure
Add your new role and environment files to the stack with your other environment files and deploy your HCI overcloud:
(undercloud)$ openstack overcloud deploy --templates \ -e [your environment files] \ -r /home/stack/templates/roles_data_hci.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/network-environment.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/net-single-nic-with-vlans.yaml -e /home/stack/templates/storage-config.yaml \ -e /home/stack/templates/storage-container-config.yaml \ -n /home/stack/templates/network_data.yaml \ [-e /home/stack/templates/ceph-backfill-recovery.yaml \ ] --ntp-server pool.ntp.org
Including
/usr/share/openstack-tripleo-heat-templates/environments/ceph-ansible/ceph-ansible.yamlin the deployment command adds the base environment file that deploys a containerized Red Hat Ceph cluster, with all default settings. For more information, see Deploying an Overcloud with Containerized Red Hat Ceph.
Include the following options in the deployment command if your deployment uses single root input/output virtualization (SR-IOV):
-e /usr/share/openstack-tripleo-heat-templates/environments/services/neutron-sriov.yaml -e /home/stack/templates/network-environment.yaml
You can also use an answers file to specify which environment files to include in your deployment. For more information, see Including environment files in an overcloud deployment in the Director Installation and Usage guide.
