Couchbase Standalone Server Setup and Configuration on Kubernetes

This article will help you to learn how to deploy and configure couchbase server standalone on kubernetes cluster.

Prerequisites

• kubernetes cluster up and running

Standalone Setup

To setup the couchbase standalone server, we will create PVC to persist the data.

pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc-data-couchbase
  namespace: ns-couchbase
  labels:
    app: data-couchbase
    env: dev
spec:
  storageClassName: default
  accessModes:
    — ReadWriteOnce
  resources:
    requests:
     storage: 20Gi

Now we will create the deployment file for the couchbase server, We are using couchbase community docker image form the docker hub.

couchbase-standalone.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  labels:
    app: data-couchbase
    env: dev
  name: data-couchbase-standalone
  namespace: ns-couchbase
spec:
  replicas: 1
  selector:
    matchLabels:
      app: data-couchbase
      env: dev
  template:
    metadata:
      labels:
        app: data-couchbase
        env: dev
    spec:
      containers:
      - image: couchbase:community-6.6.0
        imagePullPolicy: IfNotPresent
        name: data-couchbase
        volumeMounts:
          - mountPath: /opt/couchbase/var
            name: data-volume
      volumes:
        - persistentVolumeClaim:
            claimName: pvc-data-couchbase
          name: data-volume

To access the couchbase, we need to create service,

here we are using type loadbalancer service

svc.yaml

apiVersion: v1
kind: Service
metadata:
  labels:
    app: data-couchbase
    env: dev
  name: svc-data-couchbase
  namespace: ns-couchbase
spec:
  ports:
  - name: tcp-web-cb
    port: 8091
    protocol: TCP
    targetPort: 8091
  - name: tcp-memcached-cb
    port: 11210
    protocol: TCP
    targetPort: 11210
  selector:
    app: data-couchbase
    env: dev
  type: LoadBalancer

And Done, Apply the YAML files in order

kubectl apply -f pvc.yaml
kubectl apply -f couchbase-standalone.yaml
kubectl apply -f svc.yaml

Now with the loadbalancer service IP we can access the couchbase server

Server Configuration

When we browse the IP with port 8091 we we’ll see the below screen.

Click on “Setup New Cluster”, And fill the details like Cluster-name, Cluster admin user name and password,

Then click on accept terms and In next page click on “Configure Disk, Memory and Services”, Where you’ll be asked to configure hostname, service memory quota and disk paths.

Configure memory quotas as per your requirements or node limit and Click on Save & Finish !

Conclusion

I hope this guide helps you to configure the standalone couchbase server with configuration, Please refer the official couchbase website for more configurations and doubts.

Thanks !
