>
> Kubernetes supports a large variety of configurations to Pods. Currently only some of these are configurable from Spark, and they all operate by being plumbed from --conf arguments through to pod creation in the code.
> To avoid the anti-pattern of trying to expose an unbounded Pod feature set through Spark configuration keywords, the community is interested in working out a sane way of allowing users to supply "arbitrary" Pod YAML which can be merged with the pod configurations created by the kube backend.
> Multiple solutions have been considerd, including Pod Pre-sets and loading Pod template objects. A requirement is that the policy for how user-supplied YAML interacts with the configurations created by the kube back-end must be easy to reason about, and also that whatever kubernetes features the solution uses are supported on the kubernetes roadmap.
