Jenkins AWS EKS Cluster Deployment

Automated Deployment of a AWS EKS cluster with EFS CSI driver pre-configured for jenkins deployment on the EKS cluster.

Prerequisites that need to be installed

• helm (v3.8.0)
• kubectl (v1.21)
• aws-cli (v2.5.6)
• terraform (v13.0.0)

Install Infastructure

1. In the terraform folder run terraform init
2. Modify the custom.tfvars.TEMPLATE file to your liking and then rename to custom.tfvars
3. Then run terraform apply --var-file="custom.tfvars" this will take about 25min to deploy
4. Open cluster-efs-pv.yaml and apply the access-point-id, and efs-file-system-id like the example in the yaml file.
5. Once terraform has deployed the cluster you will need to update your Kubernetes context by using aws eks --region us-east-1 update-kubeconfig --name jenkins_playground

Install Jenkins

1. Check that the Kubernetes service is running kubectl get svc
2. Deploy the Amazon EFS CSI driver kubectl apply -k "github.com/kubernetes-sigs/aws-efs-csi-driver/deploy/kubernetes/overlays/stable/?ref=master"
3. Next cd into the k8s folder cd ../k8s/jenkins-pv
4. Now run the pv yaml's kubectl apply -f .\cluster-efs-claim.yaml,.\cluster-efs-pv.yaml,.\cluster-efs-sc.yaml
5. Check that they are running kubectl get sc,pv,pvc
6. Update helm repo to stable helm repo add stable https://charts.helm.sh/stable
7. Install jenkins to the cluster helm install jenkins stable/jenkins --set rbac.create=true,master.servicePort=80,master.serviceType=LoadBalancer,persistence.existingClaim=efs-claim
8. Get external IP for jenkins kubectl get svc jenkins

Cleanup

1. kubectl delete svc jenkins
2. kubectl delete -f .\cluster-efs-claim.yaml,.\cluster-efs-pv.yaml,.\cluster-efs-sc.yaml
3. cd ..\..\terraform\
4. terraform destroy
