- Check the notes for the Kubernetes version you are upgrading to at https://docs.aws.amazon.com/eks/latest/userguide/kubernetes-versions.html
- After upgrading the terraform module, remember to follow the roll nodes procedure to roll out upgraded nodes to your cluster.
Some deprecated API versions are removed by this version of Kubernetes.
Make sure you follow the instructions at https://docs.aws.amazon.com/eks/latest/userguide/update-cluster.html#1-16-prequisites before upgrading your cluster.
Metrics Server and Prometheus Node Exporter will not be managed by this module by default.
To retain the previous behaviour set:
metrics_server = true
prometheus_node_exporter = true
📝 existing resources won't be removed by this update, so you will need to remove them manually if they are no longer required. This change means that they will not be created in a new cluster, or receive updates from this module!
Existing clusters will be using separately managed security groups for cluster
and nodes. To continue to use these (and avoid recreating the cluster) set
legacy_security_groups = true on the cluster module.
Update terraform state:
wget https://raw.githubusercontent.com/cookpad/terraform-aws-eks/master/hack/update_1_15.sh
chmod +x update_1_15.sh
