So sick of a flimsy/fragile dev environment. Introducing docker at any level just increases risks, I swear.

In my experience docker makes the dev envs much more stable and predictable. It's the literal personification of "it works on my machine"

Apparently there's a bug in docker whereby if you have a health check, the health check can deadlock, but docker keeps spawning processes to run the health check.

Long story short, 2 of our servers were unresponsive yesterday because there were 65k pending health checks.

That was fun...

ssh-ing to a server that can't spawn a process for your session is... Tricky...

We have an buildprocess running that uses standartised docker containers for rhel. only the bare minimum. It has proven itself over the "i build my software on an rhelX machine and that must be available everywhere".

Docker increases stability in my experience, but it's certainly a level of indirection that can make a couple things much harder.

An colleague is at an company where docker is literally forbidden. He is frustrated because of this and other things.
