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.

  1. Rerun the openstack overcloud deploy command 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.yaml
    Copy to Clipboard Toggle word wrap

    Note

    If adding a new environment file to the overcloud, then add an additional -e argument to the openstack overcloud deploy command.
