When the cluster is over or underprovisioned and needs to be scaled.
- A running dplsh launched from
./infrastructurewithDPLPLAT_ENVset to the platform environment name.
- For general information about AKS and node-pools https://learn.microsoft.com/en-us/azure/aks/use-multiple-node-pools
There are multiple approaches to scaling AKS. We run with the auto-scaler enabled which means that in most cases the thing you want to do is to adjust the max or minimum configuration for the autoscaler.
Edit the infrastructure configuration for your environment. Eg for dplplat01
edit infrastructure/environments/dplplat01/infrastructure/main.tf.
Adjust the ..._count_min / ..._count_min corresponding to the node-pool you
want to grow/shrink.
Then run infra:provision to have terraform effect the change.
task infra:provision
