Have you looked into devcontainers? Could be a good option.
We use tilt right now for running the apps themselves. Haven’t delved into virtualized dev environments yet. We’re a Mac shop so we just have a list of brew commands to run. And for some critical tools they are invoked through docker so no cli install needed.
We have a file that houses the version and everything is done through a Makefile. So on the next main pull people will always invoke the correct version of a build tool.
Go 1.21 RC brings language improvements, new standard library packages, PGO GA, backward and forward compatibility in the toolchain and faster builds.
Go 1.21 RC released today. Some really interesting new additions. I'm pretty excited to see the map and slice package additions that contain a lot of generic methods. Will be nice not to have to maintain my own going forward.
