Infrastructure Components Updates
To update any resource in existing infrastructure, infrastructure Terraform must be reapplied with required updates.
AKS version upgrade
AKS cluster version upgrades are managed via infrastructure Terraform by updating the kubernetes_version parameter in the infra.tfvars file.
Versioning strategy
AKS is configured with automatic_upgrade_channel = "patch" command.
This make sure that the patch updates. for example: 1.34.x, are applied automatically by Azure and manual intervention is not required for patch upgrades.
