Setting up Elasticsearch Cluster on Kubernetes - Part 2 - Kibana

This is part 2 out of 3 in this series of blog posts.

Setup Kibana

Let’s try to setup kibana pointing to our elasticsearch single node cluster.

kubectl run kibana --env="ELASTICSEARCH_URL=http://elasticsearch:9200" --env="XPACK_SECURITY_ENABLED=true" --port=5601

⚠️ Notice that we have set the ELASTICSEARCH_URL to http://elasticsearch which is the name of our kubernetes pod. And the environment variable XPACK_SECURITY_ENABLED is set to true. When I tried to run without security enabled, kibana was stuck on Optimizing and caching bundles for graph, monitoring, ml, apm, kibana, stateSessionStorageRedirect, timelion, dashboardViewer and statuspage. 🤦🏽‍♂️. You can find more configuration options from their website.

You can see both elasticsearch deployment and kibana with the following command:

kubectl get deployments


elasticsearch   1         1         1            1           22m
kibana          1         1         1            0           2m

Pro tip You can keep watching the progress of your pod creation using the command:

kubectl get pods -w -l run=kibana

If the creation of the pod takes too long, might be to do with the network connection. For me, I had to wait 52 minutes for the image to be pulled down.

kubectl describe pod kibana-556b7764c7-lb4mm

Let’s expose the kibana deployment as a service:

kubectl expose deployment kibana --type=LoadBalancer

Open kibana using minikube service kibana.
