KubeCon EU 2016, part 1: Kubernetes 1.2

Yes, it became so natural for me to include a startup script with the image that generates config based on environment variables before starting the main service. It works but when the config is complex that turns the environment into very awkward mini-language that requires own maintenance, documentation etc. It is so much better to pass the config directly in its natural language.

I don't really know the history of it, but from the start there was a lot of emphasis both in Docker and in Kubernetes placed on use of environment variables. I think that kept folks from thinking of other solutions, at first.

I wonder why it took so long to come up with something like ConfigMap. With docker some images assume that the configuration is passed like in -v host-path:/etc/service/config. It works but the drawback is that host-path must present and maintained on the host complicating deployment. It is nice that Kubernetes now takes care of those complications.
