Elastic Cloud on Kubernetes
See detailed instructions from the PDF file, before the blog goes public.
- Minikube
If you need to delete your old cluster, run:
minikube delete
Configure your new Minikube cluster:
minikube config set memory 12288
minikube config set cpus 4
minikube start
Launch the Kubernetes UI:
minikube dashboard
- GKE
Download and install gcloud, kubectl on your laptop and run the following command using your GKE cluster info.
gcloud config set project elastic-sa
gcloud config set compute/zone us-central1-a
gcloud config set container/cluster aquan
gcloud auth login
gcloud container clusters get-credentials aquan --zone us-central1-a --project elastic-sa
kubectl create clusterrolebinding cluster-admin-binding --clusterrole=cluster-admin [email protected]
kubectl create clusterrolebinding adam.quan-cluster-admin-binding --clusterrole=cluster-admin [email protected]
- Deploy Elastic Cloud on Kubernetes (ECK)
kubectl apply -f https://download.elastic.co/downloads/eck/0.9.0/all-in-one.yaml
It should just take a few moment.
- Deploy Elasticsearch, Kibana, APM Server
kubectl apply -f apm_es_kibana.yaml
It might take a minute. Check the state of the Elasticsearch, Kibana and APM server pods for all of them to get ready and green.
kubectl get elasticsearch,kibana,apmserver
- Access Kibana
Port forward:
echo `kubectl get secret elasticsearch-sample-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode`
Get password of the elastic user, so that you can log into Kibana: http://localhost:5601
kubectl port-forward service/kibana-sample-kb-http 5601
- Deploy APM instrumented application
Get APM token:
echo `kubectl get secret apm-server-sample-apm-token -o=jsonpath='{.data.secret-token}' | base64 --decode`
Get APM server URL:
kubectl get services | grep apm
Edit the environment settings of the app.
Deploy the application:
kubectl apply -f shark-node.yaml
Expose as a service:
kubectl expose deployment shark-demo-deployment -n shark
Port forward:
kubectl port-forward service/shark-demo-deployment 8080 -n shark
Access the application: http://localhost:8080
