(Concourse co-creator/OSS lead here.)

Our CLI hasn't really aged well and that's something I'd like to address soon - probably going more in the direction of config files instead of flags/env vars. It'd be a lot easier to document with a proper schema. Thanks for the feedback and sorry the experience is still pretty rocky!

Awesome, thanks.

Honestly the whole application seems pretty good - but everything is focussed on more hello-world stuff, which is great for getting going on my machine - not so great for running it for real.

Whether you use environment vars or a config file, I don't mind - one benefit environment vars gives is that setting CONCOURSE_BIND_IP to the instance's IP is relatively simple, eg on AWS:

CONCOURSE_BIND_IP=$(curl http://169.254.169.254/latest/meta-data/local-ipv4)

If it's a config file then I need to update that before the application starts, which is more fiddling.

Yeah that's a good point. There are definite trade-offs to going for only one or the other. If there's a nice way to support both without too much maintenance overhead, that'd be my preference. There are a few popular Go libraries which support that, like https://github.com/spf13/viper - which we'll probably consider switching to as part of a general CLI overhaul.

For a long time now we've been primarily focusing on the core design, concepts, and architecture at the expense of documentation and introductory material and outreach - we've never had a dedicated technical writer, so documentation is really best-effort. Now that the dust is settling on our roadmap I feel a lot more confident in increasing our focus on onboarding, operability, and developer/user experience in this coming year. :)
