you're absolutely right, one needs to build images sans all of the dev toolchain and with staging/production flags. but the deps and parts they share in common should be identical. this is a hairy problem to solve, but containers are the solution, mixed with the right pattern, whatever it is. I might not want my dev containers to run on prod, but I want my staging/prod containers to be able to run on my local or whatever environment has the container/orchestration tool.
