aks-sds-deploy

Terraform code to deploy Shared Services AKS Cluster and underlying infrastructure.

Warning

When merging to this repo please check your plans for AKS version changes.

If you see a change similar to 1.34.X -> 1.34 this will bring the cluster into a failed state when applied as it rebuilds the nodes and the PDBs in the cluster will block this.

When applying with a change like this in the plan you will need to delete the PDBs with allowed disruptions set to 0 from the cluster as it applies.
