Google Kubernetes Engine

This guide shows you how to set up a Google Kubernetes Engine (GKE) cluster to which Coder can deploy.

Prerequisites

Before proceeding, make sure that the gcloud CLI is installed on your machine and configured to interact with your Google Cloud Platform account.

Set Up the GKE Cluster

The following will spin up a Kubernetes cluster using the gcloud command (be sure to replace the parameters (specifically PROJECT_ID, NEW_CLUSTER_NAME, and ZONE) as needed to reflect the needs of your environment).

gcloud beta container --project "$PROJECT_ID" \
clusters create "$NEW_CLUSTER_NAME" \
   --zone "$ZONE" \
   --no-enable-basic-auth \
   --cluster-version "latest" \
   --machine-type "n1-standard-4" \
   --image-type "COS" \
   --disk-type "pd-standard" \
   --disk-size "50" \
   --metadata disable-legacy-endpoints=true \
   --scopes "https://www.googleapis.com/auth/cloud-platform" \
   --num-nodes "2" \
   --enable-stackdriver-kubernetes \
   --enable-ip-alias \
   --network "projects/$PROJECT_ID/global/networks/default" \
   --subnetwork \
   "projects/$PROJECT_ID/regions/$ZONE/subnetworks/default" \
   --default-max-pods-per-node "110" \
   --addons HorizontalPodAutoscaling,HttpLoadBalancing \
   --enable-autoupgrade \
   --enable-autorepair \
   --enable-network-policy \
   --enable-autoscaling \
   --min-nodes "1" \
   --max-nodes "8"

To create clusters capable of supporting use of the CVMs deployment option:

gcloud beta container --project "$PROJECT_ID" \
    clusters create "$NEW_CLUSTER_NAME" \
    --zone "$ZONE" \
    --no-enable-basic-auth \
    --node-version "latest" \
    --cluster-version "latest" \
    --machine-type "n1-standard-2" \
    --image-type "UBUNTU" \
    --disk-type "pd-standard" \
    --disk-size "50" \
    --metadata disable-legacy-endpoints=true \
    --scopes "https://www.googleapis.com/auth/cloud-platform" \
    --num-nodes "2" \
    --enable-stackdriver-kubernetes \
    --enable-ip-alias \
    --network "projects/$PROJECT_ID/global/networks/default" \
    --subnetwork \
    "projects/$PROJECT_ID/regions/$ZONE/subnetworks/default" \
    --default-max-pods-per-node "110" \
    --addons HorizontalPodAutoscaling,HttpLoadBalancing \
    --enable-autoupgrade \
    --enable-autorepair \
    --enable-network-policy \
    --enable-autoscaling \
    --min-nodes "1" \
    --max-nodes "8"
