This upgrade policy from GCP is too aggressive for me, I only use 1 node pool with 1 single node. When the upgrade happens, my system is entirely down.

Is there a way to:

  • Disable automatic upgrade? or
  • Schedule the upgrade to the exact date/time? or
  • Tell Google that if they want to update please add a new temporary node in the node pool first? or
  • At least notify me via email a few days/hours before the upgrade so I can add a new node by myself?

These master node upgrades caused 1+ hour of downtime to my system twice, I'm really frustrated.

  • If you want high availability, you need redundancy. Upgrades aren't the only reason a single node can disappear without warning. – womble Nov 27 '19 at 02:22

GKE Master Nodes are managed by Google, it is not possible for customers to disable auto-upgrading.

GKE does offer a Maintenance Window feature, which provides you with additional controls for when maintenance happens I would suggest you to have a look into the best practices for upgrading the clusters. It might help you to decide solution for your concern.

Besides this, Upgrading a node pool may disrupt workloads running in that node pool. To avoid this, you can create a new node pool with the desired version and migrate the workload. After migration, you can delete the old node pool.

Unfortunately, there is no timeframe available for upgrades. Hope this information helps.
