How to Integrate Amazon EKS and Jenkins

问题

I'm currently using Kubernetes Client Plugin in Jenkins but still it's confusing to configure, because it looks for Kubernetes config, and those credetials are not available even I configured them in the credentials section.

Please see the screenshot below for my credentials which are configure in my Jenkins.

When I do try to add those credentials from Jenkins side, which is not listed under the Kubernetes credentials. The red colored are has no kist of my credentials.

How can I configure this Kubernetes plugin in Jenkins ? or any other alternative methods to configure Jenkins + Amazon EKS ?

Thanks.

To reproduce your issue I have installed EKS using Deploying a Kubernetes Cluster with Amazon EKS article.

After adding worker nodes next steps were performed:

1) install helm

2) install jenkins from stable/jenkins chart.

curl https://raw.githubusercontent.com/helm/helm/master/scripts/get | bash
kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
helm init --service-account tiller
helm search jenkins
helm install stable/jenkins --name myjenkins

If you want to change any parameters before deploying helm chart, you can first download and edit values.
helm inspect values stable/jenkins > /tmp/jenkins.values
helm install stable/jenkins --values /tmp/stable_jenkins.values --name myjenkins

Wait until everything will be deployed, you can check via watch kubectl get all --all-namespaces

kubectl get all --all-namespaces

Next

1. Get your 'admin' user password by running:
  printf $(kubectl get secret --namespace default myjenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo
2. Get the Jenkins URL to visit by running these commands in the same shell:
  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        You can watch the status of by running 'kubectl get svc --namespace default -w myjenkins'
  export SERVICE_IP=$(kubectl get svc --namespace default myjenkins --template "{{ range (index .status.loadBalancer.ingress 0) }}{{ . }}{{ end }}")
  echo http://$SERVICE_IP:8080/login

3. Login with the password from step 1 and the username: admin

• Open browser, login and go to "Manage Jenkins"-->"Configure System"--> Cloud Section

• Click Add - Jenkins

• Choose Kubernetes Service Account and click add..

• Next chose "Secret Text" in drop down menu left to Add button, Test connection, apply and save.

-Check Credentials:

-Check again "Manage Jenkins"-->"Configure System"--> Cloud Section

Hope it helps...
