hi Venkash, I did same as you it worked. But once i run the command in shell like "kubectl get po" it said the command is not found. This is caused by the pod does not have kubectl cli installed. Any idea from you incase we need to run the kubernetes cli on the slave pod?
Hi Thanh, the container image I used in this video for jenkins slave pod doesn't have kubectl binary. If you want you have to bake it inside the image, host it in your local container registry somewhere and pull it from there or check in docker hub if an image with docker and kubectl installed.
Thank you for your video, and I have a question that I always get ip is 127.0.0.1 when run "kubectl config view". How do I get real ip so that jenkins container can access it?
Is there any documentation on the service account that the agent uses inside kubernetes. Instead of using the default . What are the privs that we should provide the service account for the agent if we dont wanna use the clusterAdmin.
I tried the same steps, but for a newer version of jenkins. My pod is getting created on the cluster but in jenkins the node is showing as offline. I also get messages like waiting for agent to connect in the agent log section of jenkins. Any help would be appreciated :)
Thank you for your video, but it is not working when you run kubectl command from pipeline or docker build command.... it says docker not found and kubectl not found
@@TheQuranVerses1 Hi, thanks for watching. I am sure I have mentioned in this video that you have to use a jenkins slave image that has docker and kubectl baked into it. The slave jenkins slave image i used in this video has docker binary built into it. Not sure if you are using the same image. Check if your image has docker in it or use one with docker in it.

Hi Anandha, thanks for watching. Did you check the jenkins log? You will find a clue as to why its failing to provision the slave pod. Usually it will be due to an incorrect pod template configuration in Jenkins.
@@justmeandopensource Hi Venkat, same error. Pod is getting created in the cluster and within a minute it is dead and new pods will come and this same is happening in a loop. Also in logs, I can see that the Slave pod is not able to connect on port 50000 which is already enabled in my Jenkins. Also, I tried to go inside the pod and ping my Jenkins host which is outside my cluster and pod is not able to resolve my Jenkins server IP. Please help. Thanks in Advance.
@@irfanansari6448 Okay. If you think that the slave pods can't talk back to Jenkins master, then I believe the problem lies in the slave pod configuration in your Jenkins master. You know when you configure Kubernetes cloud, further down the line you configure the slave pods and the containers and the image it uses, the volumes and stuff. There you would have configured JENKINS_URL environment variable. There you could specify the ip address of the jenkins master instead of dns name. You just need to make sure that slave pods can talk to Jenkins. Whether its a firewall thing or AWS security group thing, you just need to sort that out.
Thanks for video for very precise demonstration. I tried it but I am facing issue as my slave pod is getting recreated continuously with no console logs in job. Slave is always offline, when debed it further I see connection time out in container logs.
