2021-11-25 AKS and EKS clusters upgrade (1.19 > 1.20) [INFRA-3118]

Hello everybody,

We’ll do an AKS and EKS clusters upgrade from 1.19 to 1.20 this Thursday, 25th of November 2021, starting at 08:00 UTC

No interruption is expected, except for the non-replicated services such as ldap.jenkins.io, infra.ci.jenkins.io or release.ci.jenkins.io that need to be restarted in order to be migrated to the new nodes.

You may find the notes about this upgrade at the following location: Jenkins AKS and EKS Kubernetes Upgrade to 1.20 - HackMD
It contains all the links, comment, discussions.

Here is also the corresponding Jira issue: [INFRA-3118] Upgrade to Kubernetes 1.20 - Jenkins Jira

Regards,

Hervé Le Meur

Upgrade completed, all services are up and running :slight_smile:
