Deploy East cluster

Run the following commands to deploy the first cluster:

minikube start -p $CLUSTER_EAST --network istio --memory 8g --cpus 4

For both clusters, we need to configure MetalLB, which is a load balancer. This is because we need to assign an external IP to the required ingress gateways to enable cross cluster communication between Istio and the applications installed.

minikube addons enable metallb -p $CLUSTER_EAST

We set up some environment variables with IP ranges that MetalLB will then assign to the services:

MINIKUBE_IP=$(minikube ip -p $CLUSTER_EAST)
MINIKUBE_IP_NETWORK=$(echo $MINIKUBE_IP | sed -E 's/([0-9]+\.[0-9]+\.[0-9]+)\.[0-9]+/\1/')
MINIKUBE_LB_RANGE="${MINIKUBE_IP_NETWORK}.20-${MINIKUBE_IP_NETWORK}.29"

cat <<EOF | kubectl --context $CLUSTER_EAST apply -f -
apiVersion: v1
kind: ConfigMap
metadata:
  namespace: metallb-system
  name: config
data:
  config: |
    address-pools:
    - name: default
      protocol: layer2
      addresses: [${MINIKUBE_LB_RANGE}]
EOF

We should have the first cluster deployed and ready to use.
