GKE

To create a Google Kubernetes Engine you have to do so in a Google Cloud Project. Assuming you have already do so and that you have installed the gcloud CLI you can proceed by creating the kubernetes cluster with following characteristics (that you may change):

We recommend disable auto upgrade

  • Project: my-project
  • Cluster name: stackgres
  • GKE version: 1.21.3-gke.2001
  • Zone: us-west1
  • Node locations: us-west1-a,us-west1-b,us-west1-c
  • Machine type: e2-standard-4
  • Number of nodes: 3
  • Disk size 100GB
  • Node auto upgrade/repair disabled
gcloud beta container \
 --project "my-project" clusters create "stackgres" \
 --region "us-west1" \
 --no-enable-basic-auth \
 --cluster-version "1.21.3-gke.2001" \
 --no-enable-ip-alias \
 --release-channel "None" \
 --machine-type "e2-standard-4" \
 --image-type "COS_CONTAINERD" \
 --disk-type "pd-standard" \
 --disk-size "100" \
 --metadata disable-legacy-endpoints=true \
 --num-nodes "3" \
 --no-enable-autoupgrade \
 --no-enable-autorepair \
 --node-locations "us-west1-a","us-west1-b","us-west1-c"

Output will be similar to this:

WARNING: Starting with version 1.18, clusters will have shielded GKE nodes by default.
WARNING: Your Pod address range (`--cluster-ipv4-cidr`) can accommodate at most 1008 node(s).

To cleanup the kubernetes cluster you may issue following command:

gcloud -q beta container \
  --project "my-project" \
  clusters delete stackgres \
  --region us-west1

You may also want to cleanup compute disks used by persistence volumes that may have been created:

gcloud -q compute disks list --project my-project --filter "zone:us-west1" | tail -n+2 | sed 's/ \+/|/g' | cut -d '|' -f 1-2 \
  | grep '^gke-stackgres-[0-9a-f]\{4\}-pvc-[0-9a-f]\{8\}-[0-9a-f]\{4\}-[0-9a-f]\{4\}-[0-9a-f]\{4\}-[0-9a-f]\{12\}|' \
  | xargs -r -n 1 -I % sh -ec "gcloud -q compute disks delete --project my-project --zone \"\$(echo '%' | cut -d '|' -f 2)\" \"\$(echo '%' | cut -d '|' -f 1)\""
