...

1. Stop all octavia-services by adding the following keys to hiera, and then make sure to run puppet on the octavia hosts:

   1. octavia::housekeeping::enabled: false

   2. octavia::health_manager::enabled: false

   3. octavia::api::enabled: false

   4. octavia::worker::enabled: false

2. Do one of:

   1. Reinstall the node with yoga modules/tags

   2. Run puppet with the yoga modules/tags, Run apt-get dist-upgrade && apt-get autoremove, Run puppet

3. Run octavia-db-manage upgrade head


4. Re-start octavia services by removing the keys added in step 1 and re-run puppet.

5. Build a yoga-based octavia-image and upload to glance. Tag it and make octavia start to replace the amphora.

Horizon

1. Run puppet with the yoga modules/tags
2. run dnf upgrade --allowerasing

3. Yes this is weird: Login to all memcached servers, and run systemctl restart memcached
4. Run puppet again
5. restart httpd

Compute-nodes

When all APIs etc. are upgraded, it is time to do the same on the compute-nodes. Compute nodes are simple to upgrade:

...

• Run nova-manage db online_data_migrations on a nova API node. Ensure that it reports that nothing more needs to be done.
• Rotate octavia images.
• Remove old authtoken-related keys from hiera:
  • barbican::keystone::authtoken::*
  • cinder::keystone::authtoken::*
  • heat::keystone::authtoken::*
  • magnum::keystone::authtoken::*
  • magnum::keystone::keystone_auth::*
  • octavia::keystone::authtoken::*
• Remove old database-connection keys from hiera:
  • barbican::db::database_connection
  • magnum::db::database_connection
  • nova::db::api_database_connection
  • nova::db::database_connection
  • octavia::db::database_connection
• Remove other keys which now have sane defaults that we do not need to override:
  • barbican::api::max_allowed_secret_in_bytes
  • barbican::api::max_allowed_request_size_in_bytes
