Updating Undercloud Components

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

Clean the yum cache to ensure only the new repos are used:
```
sudo yum clean all
```
Stop services so that they are not restarted by packaging scripts when they are updated. The service restarts will be handled by the undercloud upgrade command after new configuration has been applied.:
```
sudo systemctl stop openstack-*
sudo systemctl stop neutron-*
sudo systemctl stop openvswitch
sudo systemctl stop httpd
```
Update the TripleO CLI package:
```
sudo yum -y update python-tripleoclient
```
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
```
Proceed with package_update.
