Assuming, you have AWS account, installed AWS CLI, kubectl, eksctl, helm etc. Already created EKS cluster.

Steps to create EFS File System

1. Provide your VPC

2. SG if you don't have earlier

3. For EFS-SecurityGroup(SG), also allowed port 2049

4. Create EFS https://docs.aws.amazon.com/efs/latest/ug/creating-using-create-fs.html

5. Mount Targets in each of the AZ if required (via CLI)

aws efs create-mount-target \

--file-system-id identifier for our file system (i.e. fs-123b45fa) \

--subnet-id identifier for our node group subnets (i.e. subnet-

1234567ab12a345cd) \

--security-group identifier for the security group created for our

Amazon EFS mount targets (i.e. sg-1234567ab12a345cd) \

--region us-east-1 (change region and other parameters accordingly)

6. Create Access point https://docs.aws.amazon.com/efs/latest/ug/efs-access-points.html

or via cli

aws efs create-access-point --file-system-id identifier for our file

system (i.e. fs-123b45fa) \

--posix-user Uid=1000,Gid=1000 \

--root-directory

"Path=/jenkins,CreationInfo={OwnerUid=1000,OwnerGid=1000,Permissions=777}"

# Deploy EFS CSI driver to your EKS

kubectl apply -k "github.com/kubernetes-sigs/aws-efs-csi-

driver/deploy/kubernetes/overlays/stable/?ref=master"

Output: Should say something like efs-csi-node created

Create efs-sc.yaml

Create efs-pv.yaml

Create efs-pvc.yaml

Deploy them

kubectl apply -f

efs-sc.yaml,efs-pv.yaml,efs-pvc.yaml

# Deploy Jenkins

(Add stable chart repo)

helm repo add stable https://kubernetes-charts.storage.googleapis.com/

(Install jenkins) # change accordingly

helm install jenkins stable/jenkins --set

rbac.create=true,master.servicePort=80,master.serviceType=LoadBalancer

,persistence.existingClaim=efs-pvc

(Ingress loadbalancer name)

printf $(kubectl get service jenkins -o

jsonpath="{.status.loadBalancer.ingress[].hostname}");echo

( to get admin passwd)

printf $(kubectl get secret jenkins -o jsonpath="{.data.jenkins-admin-

password}" | base64 --decode);echo
