It looks like you're trying to allow the same pipeline to run using either
Kubernetes agents or some other type of agent. Is that realistic? In my
experience, there are a number of things one has to pay attention to in a
Kubernetes agent, especially if it's a multi-container pod.
I'm not sure how flexible a declarative pipeline can be, but it is
certainly possible to have a scripted pipeline determine which type of node
in which to run steps at run time. The node() syntax takes a string
expression. You can pass a block to a method which conditionally calls the
block inside a podTemplate() or not.
