Running ECK on Google Kubernetes Engine (GKE)

💡 Recommended if you're using Google Cloud Platform and want to try it on a realistic cluster.

1. Install tools specified in the previous section (Docker, kubectl, skaffold)

2. Create a Google Kubernetes Engine cluster and make sure kubectl is pointing to the cluster.

   gcloud services enable container.googleapis.com

   gcloud container clusters create huage-eck-demo --num-nodes=3 --zone=europe-west1-b \
   --machine-type "n1-standard-2" --network "projects/elastic-sa/global/networks/default" \
   --subnetwork "projects/elastic-sa/regions/europe-west1/subnetworks/default"  \
   --enable-ip-alias --no-enable-master-authorized-networks --addons HorizontalPodAutoscaling,HttpLoadBalancing 

   kubectl get nodes
   

3. Enable Google Container Registry (GCR) on your GCP project and configure the docker CLI to authenticate to GCR:

   gcloud services enable containerregistry.googleapis.com

   gcloud auth configure-docker -q

4. Apply the ECK operator

   kubectl apply -f eck-all-in-one.yaml

   Verify the status of ECK operator

   kubectl -n elastic-system logs -f statefulset.apps/elastic-operator

5. Create Elasticsearch nodes

   kubectl apply -f es-nodes.yaml

   Verify elasticsearch status

   kubectl get service eckdemo-es-http

   Retrive elasticsearch secret

   echo $(kubectl get secret eckdemo-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode)

6. Create Kibana nodes

   kubectl apply -f kibana-nodes.yaml

   Verify Kibana status

   kubectl get service eckdemo-kb-http
