Workers: Scaling
There are two easy ways to add worker nodes to a cluster:
- Add entries to
worker_pools
. - Increase the
size
of aworker_pools
entry.
Worker pools can be added and removed, their size and boot volume size can be updated. After each change, run terraform apply
.
Scaling changes to the number and size of pools are immediate after changing the parameters and running terraform apply
. The changes to boot volume size will only be effective in newly created nodes after the change is completed.
