Jenkins kubernetes plugin not working

Question

I am trying to setup Jenkins Dynamic slaves creation using jenkins-kubernetes plugin.

My jenkins is running outside K8s Cluster.

Ok! I find the issue, I am giving container cap as 10 (in default Namespace)which is too low for my cluster. I have 15 Worker nodes cluster and when K8s master trying starting a pod it starts multiple pods at once(though terminates rest after one is scheduled) which eventually crosses the container cap limit(which was 10). I changed the CAP to 100 and now things are working as expected.

One thing which I noticed with K8s Jenkins plugins, it will not clear out the error container itself which increases the container count and leads to this problem.
