Install Jenkins on AWS EKS using Helm

Prerequisites

  • Create namespace for jenkins
    •                     
kubectl create ns jenkins
  • We'll store jenkins data on AWS EBS as persistent storage hence for that
    • Create storage class
      •                             
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: jenkins-sc
provisioner: kubernetes.io/aws-ebs
parameters:
  type: gp2
  fsType: ext4
    • Create persistent volume claim
      •                             
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: jenkins-pvc
  namespace: devops-tools
spec:
  storageClassName: jenkins-sc
  resources:
    requests:
      storage: 50Gi
  accessModes:
    - ReadWriteOnce
  • Install using Helm - In this command we've set few values like namespace, pvc, sc - as created in intial steps; service type, jenkins master and slave resource requests and limit for fine grained usage of all resources under EKS
    •                     
helm install ng-jenkins stable/jenkins --set namespaceOverride=jenkins,master.serviceType=LoadBalancer,master.slaveKubernetesNamespace=jenkins,master.resources.requests.cpu=500m,master.resources.requests.memory=1Gi,master.resources.limits.cpu=500m,master.resources.limits.memory=1Gi,persistence.existingClaim=jenkins-pvc,persistence.storageClass=jenkins-sc,master.adminPassword=admin

How to check

            
kubectl get sc -n jenkins
kubectl get pvc -n jenkins
kubectl get pv -n jenkins
helm list -n jenkins
kubectl get po -n jenkins
kubectl get pvc -n jenkins
