Setup Nexus OSS On Kubernetes

First lets create a namespace called devops-tools

1 | create a namespace called devops-tools

kubectl create namespace devops-tools

2 |Create the deployment using kubectl command

Now create nexus.yml file and copy following code in that.

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: nexus
  namespace: devops-tools
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: nexus-server
    spec:
      containers:
        - name: nexus
          image: sonatype/nexus3:latest
          resources:
            limits:
              memory: "4Gi"
              cpu: "1000m"
            requests:
              memory: "2Gi"
              cpu: "500m"
          ports:
            - containerPort: 8081
          volumeMounts:
            - name: nexus-data
              mountPath: /nexus-data
      volumes:
        - name: nexus-data
          emptyDir: {}

3 | Create the deployment using kubectl command

kubectl create -f nexus.yml

4 | Check the deployment pod status

 kubectl get pods -n devops-tools

Now create nexusservice.yml file and copy following code in that.

apiVersion: v1
kind: Service
metadata:
  name: nexus-service
  namespace: devops-tools
  annotations:
      prometheus.io/scrape: 'true'
      prometheus.io/path:   /
      prometheus.io/port:   '8081'
spec:
  selector:
    app: nexus-server
  type: NodePort
  ports:
    - port: 8081
      targetPort: 8081
      nodePort: 32000

5 |Create Service using kubectl command

kubectl create -f nexusservice.yml
