Updating Undercloud Components

You can upgrade any packages that are installed on the undercloud machine.

  1. Remove all Delorean repositories:


    You may wish to backup your current repos before disabling them:

    mkdir /home/stack/REPOBACKUP
    sudo mv /etc/yum.repos.d/delorean* /home/stack/REPOBACKUP
    sudo rm /etc/yum.repos.d/delorean*
  2. Enable new Delorean repositories:

  1. Clean the yum cache to ensure only the new repos are used:

    sudo yum clean all
  2. Update required package:


    It is strongly recommended that you validate the state of your undercloud before starting any upgrade operations. The tripleo-validations repo has some 'pre-upgrade' validations that you can execute by following the instructions at validations to execute the "pre-upgrade" group:

    mistral execution-get-output $(openstack workflow execution create -f value -c ID tripleo.validations.v1.run_groups '{"group_names": ["pre-upgrade"]}')

    Newton to Ocata

    The following commands need to be run before the undercloud upgrade:

    sudo systemctl stop openstack-*
    sudo systemctl stop neutron-*
    sudo systemctl stop openvswitch
    sudo systemctl stop httpd
    sudo yum -y update instack-undercloud openstack-puppet-modules openstack-tripleo-common

    Ocata to Pike


    Prior to Pike, TripleO deployed Ceph with puppet-ceph. With the Pike release it is possible to use TripleO to deploy Ceph with either ceph-ansible or puppet-ceph, though puppet-ceph is deprecated. To use ceph-ansible, the CentOS Storage SIG Ceph repository must be enabled on the undercloud and the ceph-ansible package must then be installed:

    sudo yum -y install --enablerepo=extras centos-release-ceph-jewel
    sudo yum -y install ceph-ansible

    Update TripleO CLI package:

    sudo yum -y update python-tripleoclient
  3. Run the undercloud upgrade command. This command will upgrade all packages and use puppet to apply new configuration and restart all OpenStack services:

    openstack undercloud upgrade


    You may wish to use time and capture the output to a file for any debug:

    time openstack undercloud upgrade 2>&1 | tee undercloud_upgrade.log


    If you added custom OVS ports to the undercloud (e.g. in a virtual testing environment) you may need to re-add them at this point.
