Hi Everybody,

Tomorrow, we'll do an AKS cluster upgrade from 1.17 to 1.18.

The procedure upgrades one machine at a time so most services should remain up and running.

The services "release.ci", "infra.ci" and the ldap service will be restarted in the process as the containers get rescheduled to other nodes.

We didn't identify major risk for this upgrade

We are continuously improving the process so, feel free to provides feedbacks on the notes and we will incorporate them in the next upgrades.
