I've created a cluster using
eksctl create cluster -f mycluster.yamleverything is running but now I would want to add cluster autoscaler. There does not seem to be an option to specify this for the eksctl update cluster command.
When creating a new cluster I can add the --asg-access flag, is there an option to enable ASG support for an existing cluster via eksctl?
The --asg-access flag only adds relevant iam policy and labels to a node group.
You can do that by creating a new node group with the autoscaler option set as true
nodeGroup:
iam:
withAddonPolicies:
autoScaler: trueand the labels as mentioned here
Then you need to install the autoscaler itself
Note:
You won't be able to edit your current nodeGroup, so you will have to add a new one first and then delete your current one. (https://eksctl.io/usage/managing-nodegroups/#nodegroup-immutability)
