#In this tutorial I gather yaml file for implementing gitlab and Jenkins on kubernetes cluster. Including 2 scenario , first one is deploy gitlab with exposing service using imprative command line and ingress resource and implementing ssl-tls on port 443 . The second scenario is to implement Jenkins with service and ingress resource on http without ssl-tls on port 80 and nodeport for agent connectivity.
1- For gitlab there are 2 files which is deploy gitlab as a deployment with persistent volume and persistent volume claim (gitlab-deployment.yaml) on the second file is how to implement gitlab Ingress resource based on port 443 SSL TLS. (gitlab-ingress-resource.yaml) Before ran into the ingress resource for gitlab you have make ssl-tls file and then provide it to the secret component , you can use valid cert or using openssl or either using lets encrypt. A. make dns pointer or subdomain as you need and deploy gitlab-deployment.yaml B. make your self sign certificate or any other tools (I just used lets encrypt for domain ) c. make secret in type of tls and import your cert/key files in it
1.1
kubectl create secret tls tls-secret \
--namespace=kubernetes-dashboard \
--cert=/etc/letsencrypt/live/gitlab.yourdomain.com/fullchain.pem \
--key=/etc/letsencrypt/live/gitlab.yourdomain.com/privkey.pem
1.2 # make a service for your gitlab using imprative command:
kubectl expose deployment -n gitlab-ns gitlab-deployment --name=gitlab-clusterip-svc --port=443 --target-port=443
kubectl expose deployment -n gitlab-ns gitlab-deployment --name=gitlab-clusterip-svc-ssh --port=22 --target-port=22
Now it is a time to deploy your ingress resource yaml file ==> (gitlab-ingress-resource.yaml)
2- For Jenkins there are 3 files including Jenkins deployment with persistent volume and persistent volume claim . and the Ingress resource and also Nodeport connectivity for Jenkins agent. A. deploy Jenkins using Jenkins-deployment.yaml on your cluster , !!!!!!! this time it has service you do not need to use the imprative command to expose it. !!!!!!!! B. deploy ingress resource using Jenkins-ingress-resource.yaml . C. deploy Jenkins-nodeport-for-agent-connectivity.yaml , for other agents which they want to connect to your master and be a worker.
