[ Kube 25 Discussion 1 ] Configuring Jenkins to connect to Kubernetes cluster

In this video, I will show you how to connect your existing Jenkins server to your Kubernetes cluster. I did a video on Running Jenkins in Kubernetes cluster and launching slave jenkins pods in the kubernetes cluster. This video is about connecting the existing Jenkins server outside of Kubernetes cluster and running the slave pods withing the K8s cluster.

@@justmeandopensource well, I have a question, that I am new in kubernetes, following your tutorial I could create the connection with my kubernetes, but the question is, I have a vm of jenkins, and then I have my kubernetes aks, jenkins is not in this kubernetes . At the time of testing your video, the pod appears but stays pending all the time, as I read it does not connect because I do not have a jnlp slave in kubernetes, and that is what I do not understand, I would like to know how I make a connector Among them, I have seen that they open a jenkins slave with port 5000 but I do not quite understand. Regards, and thank you very much

[@justmeandopensource]

@@jackymorales3714 Yes. In your jenkins configuration, you would have set the jnlp port (50000). This is the port the slaves (pods in k8s cluster) will use to connect to the master. In the slave pod configuration in kubernetes plugin in your Jenkins master, you will have defined the jenkins url that this slave pod will connect to. So your 50000 port on jenkins vm must be reachable from internet for your slave pod in AKS to connect to.

Thank you very much for your series of tutorials on Kuberntes, it helped me very much. Do you know any way to configure Github webhook for CI/CD, if Jenkins is running on Kubernetes Cluster in a local environment. I would really appreciate it, if you could share your thoughts on that topic. Thanks again for tutorials!

[@justmeandopensource]

Hi Ali, thanks for watching this video and thanks for your interest in this channel. In order to configure Github webhook (to trigger a pipeline in Jenkins), your Jenkins service must be accessible to the internet. Given you are running Jenkins in a Kubernetes cluster in your local environment, you won't be able to connect Github to Jenkins using webhooks. That is unfortunate.

Able to configure without any issues. Let me know is it possible to scale the Jenkin-slave pods ? The use case is, if all my workers in Jenkins goes full, I want to auto scale (increase the number of slaves) if it comes back down, I would like to reduce the slaves count.

[@chalasanisasi]

Great video. Question .....How can I edit the config file of jenkins to edit some security settings? Since this is hosted on k8s, not sure which server/node to look at. btw...jenkins pod mounted on ebs volume. Currently i can view the jenkins file like -> kubectl exec -t -i jenkins-pod-name -n jenkins cat /var/jenkins_home/config.xml But if I want to edit it how can I go about that?

[@justmeandopensource]

hi Narayan, thanks for watching. In this video, I connected an existing jenkins master to a kubernetes cluster and the slaves run as pods in the cluster. When you say, you want to edit the jenkins config, is it the jenkins master or the jenkins slave config? If its the jenkins master, you can configure it through dashboard web ui. If its the slave pods running in kubernetes cluster, you shouldn't be configuring it on the pod. Instead, you should be updating the jenkins slave container image itself. Or in the kubernetes cloud plugin configuration page for any settigs related to slave.

[@poshlyak343]

As always, a great video. But what if Jenkins is in the same Kubernetes cluster, and need to connect another one? I encountered a jenkins slave unavailability problem on port 50000. I changed the port type to Node Port to access jenkins slave from outside the cluster. How bad is that?

[@justmeandopensource]

Hi, thanks for watching. You can have and run multiple jenkins instances within the cluster absolutely fine. You just need to make sure they run and are exposed on different ports, thats it. I have recorded a video and will be released tomorrow which is about using jenkins operator for deploying and managing jenkins instances. Cheers.

hello sir, i started jenkins locally ( as a windows service not in docker ) and minikube started. but when i run the job the commands given in executable shell is not executed inside pod but in windows host. can you help me with this?

[@justmeandopensource]

Hi Abhishek, thanks for watching. When creating the job, please specify the node label to target the pod. So when configuring the Kubernetes plugin in Jenkins, you had given the pod details. You will also have option to set labels there. And in the job configuration you have to specify that label so the job gets executed only on the node with that label. Hope it makes sense. Or temporarily you can set the number of executors in jenkins master to 0 and the job will be launched on the pod. Cheers.

Hi Venkat I can use Jenkins on Kubernetes or use on Jenkins server (not in Kubernetes). I don't know What are the best practices?

[@justmeandopensource]

Hi Vatcharin, Thanks for watching this video. Each approach has its own benefits. If you have an existing Kubernetes cluster and wanted to containerize and move all the applications you manage into Kubernetes, then you can move it. There are lots of advantages of running any application in a Kubernetes environment or in general any container platform. Scalability is one such advantage. For example if you application is getting more traffic, you can just scale the number of replicas/instances of your application. There are also auto-scaling options. You can de-couple application and storage by using persistent volumes. Lot more advantages are there. Cheers.

[@justmeandopensource]

And also one more script which gets excited at every day 9: 30 AM Monday to Friday and resume the GCP node pool and also the SQL database without changes in cluster 3. the Second query I have an artifact and my application is running in multi-cloud on GCP, AWS, Azure through Jenkins in an automated way that artifact should move at the same time into all application servers feel free to wait for ur guidance.

For passing the kubeconfig file, If I am creating a parameterized job that can be used by multiple people each having different config files, how can I pass this parameter value (i.e. the path to kubeconfig file to 'Kubernetes CLI' part. I don't want the users to 'Configure' the job. They should only be able to 'Build with Parameter' and pass the kubeconfig file to a parameter. Any way to accomplish this?

Hi Ravi, thanks for watching. I have had that problem couple times. Have a look in the jenkins logs and see why the slave pods are being terminated as soon as its launched.

Hi Yash, thanks for watching. Did you set up the cluster yourself in the cloud or are you using managed kubernetes service where the cloud provider manages the control planes while you are in control of the worker nodes? The kubeconfig file is auto generated and will have the reachable ip address of the control planes. It can either be public or private ip of the control planes depending on whether you are exposing your cluster to the internet or if its going to be internal.

@@srivatsamarichi2536 Okay. So you want Jenkins Tunnel in jenkins agent configuration in the Kubernetes plugin. It depends on where your Jenkins server is. If the jenkins server is also running inside the cluster, you can use the clusterIP:50000 of the jenkins service. If you are using jenkins outside k8s cluster, then the ip address of the jenkins server. This video is about connecting your existing Jenkins server (that is outside the k8s cluster) to your k8s cluster and run jenkins agents inside the cluster. I have specified the Jenkins Tunnel configuration at 10:10 I have also done a video on running Jenkins inside the k8s cluster. kzbin.info/www/bejne/hZOqg2N7m7uDosk Jenkins Tunnel will be the clusterip of the jenkins service.

Cool. I tried specifying the clusterip:50000 in the Jenkins tunnel. The JNLP pod comes up in a suspended mode without running any job. When I see the logs, it's referring 2 images and creating 2 pods. Don't know why it's referring 2 places to pull the images from.
