Static IP for GKE cluster

static-ip-gke.md

Create a Kyma cluster. By default, GKE uses the Ephemeral IPs. The best option is to use the Cloud NAT together with GKE to get the static IP.

But for demo purpose, the easiest way for me was to disable the auto-scaling and change IP of each VM instance from the existing node pool to Static. (non-production option!)

Disable autoscaling for an existing node pool:

1. Visit the Google Kubernetes Engine in GCP Console.

2. Choose the cluster and its node pool and click its Edit button, which looks like a pencil.

3. Disable Enable autoscaling option.

4. Click Save.

Change VM instance IP version

1. Visit the External IP addresses

2. Choose the IP entry assigned to your VM instance.

3. Select static option from dropbox menu in Type column.

4. Set static name and click create.

NOTE: Do that for each instance from your node pool.
