direnv is our magic sauce for this. We enforce that all devs store the current context in an environment variable (KUBECTL_CONTEXT), and define the appropriate kubectl alias to always use that variable as the current context. To do stuff in a cluster, cd into that cluster’s directory, and direnv will automatically set the correct context. I also change prompt colors based on the current context.

(This way, the worst you can do is re-apply some yaml that should’ve already been applied in that cluster anyway)

We also have a Makefile in every directory, where the default pseudo-target is the thing you want 99% of the time anyway: kustomize build | kubectl apply -f -
