Chapter 11. Updating the Environment
This chapter explores how to update your environment after creating your Overcloud of choice. This includes updating aspects of both the Undercloud and Overcloud.
11.1. Updating Director Packages
The director relies on standard RPM methods to update your environment. This involves ensuring your director's host uses the latest packages through
yum:
$ sudo yum update
Important
After the package update, make sure all OpenStack services are running properly on the director. Check the
ironic-api and ironic-discoverd services are running. If not, please start them:
$ sudo systemctl restart openstack-ironic-api openstack-ironic-discoverd
Likewise,
heat-engine on the Undercloud can fail to start if its database is unavailable. If this occurs, restart heat-engine manually after the update:
$ sudo systemctl start openstack-heat-engine.service
