Hi @lucasvaltl , can you help me? I'm not sure what is needed from Team Workspace for this issue. Is there something specific that is needed?

[shaoye]

we can confirm it doesn't work on EKS either. (the node group can't scale up after scaling down to 0)

our asg has the tags set correctly

k8s.io/cluster-autoscaler/enabled -> true
...
k8s.io/cluster-autoscaler/node-template/label/gitpod.io/workload_workspace_regular -> true

we also tried to add these 2 labels to the tags and it still didn't work

k8s.io/cluster-autoscaler/node-template/label/gitpod.io/registry-facade_ready_ns_gitpod -> true

k8s.io/cluster-autoscaler/node-template/label/gitpod.io/ws-daemon_ready_ns_gitpod -> true
