Don't Define The Same Env Var Multiple Times With Kubernetes

Kubernetes environment variables for CronJobs or Pods are defined as a list. You can technically define the same environment variable multiple times, and it will take the last one on the list.

However, I’ve found that this leads to strange behavior with Kubernetes tooling, and I’ve since avoided this practice.

For example, I’ve seen ArgoCD fail to generate a diff because two environment variables have the same name.
