Chapter 2. Updating the overcloud configuration
At times you will need to update the Red Hat Hyperconverged Infrastructure (RHHI) for Cloud configuration to add new features, or change the way the overcloud functions.
Prerequisite
- A running RHHI for Cloud solution.
Procedure
Do the following step on the Red Hat OpenStack Platform director node, as the stack user.
Rerun the
openstack overcloud deploycommand with the same TripleO Heat templates from the initial overcloud deployment:Example
[stack@director ~]$ openstack overcloud deploy --templates \ -r ~/custom-templates/custom-roles.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/puppet-pacemaker.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml \ -e ~/templates/network.yaml \ -e ~/templates/ceph.yaml \ -e ~/templates/compute.yaml \ -e ~/templates/layout.yamlNoteIf adding a new environment file to the overcloud, then add an additional
-eargument to theopenstack overcloud deploycommand.
