Answer 1

This error might be due to not creating the label ‘jenkins-eks-pod’ on the jenkins server.

To create a label on the jenkins server :

go to manage jenkins > Manage nodes and Clouds > labels and then enter the label name.

Post creating this label try to run the job and check if it works.

As per the error No httpclient implementations found on the context classloader You need to upgrade jenkins kubernetes plugin to 3802. This error No httpclient implementations found on the context classloader is fixed in this release. Refer to this jenkinsci/kubernetes-plugin/releases/tag/3802.
