How in the hell do you use go modules with a complex app with multiple directories. about project-layout HOT 7 OPEN

This go module hell is real people!

Switching from dep to go modules is pretty easy @rhugga

first activate go mod if not active

$ export GO111MODULE=on

to switch from dep to go mod

$ go mod -init
$ go build ./...
$ rm -rf vendor Gopkg.* # look ma no hands
$ go list -m all

so go build ./... will fetch your dependencies and add them to go.mod and go.sum.

i already have two apps under my profile but i guess there is a lot of apps started to switch to go mod since dep not maintained anymore

I have wondered this as well. Where do go.mod and go.sum end up in a complex project?

@williamh still no answers?

@williamh typically go.mod and go.sum should be in the project root. kubernetes is one example.

I also have to anchor it with a .MODULE_ROOT file in the project root and have a GetModuleRootPath() function in the root package that knows how to search and find the root project path in order to find assets required for the unit-tests. Need to set a variable for it in Travis CI config. Have been unable to find any other way (since all of the projects flatten into executables and there is only a limited concept of a tree at the end).

The Kubernetes Go client is a good example of the go module versioning hell: so far, the Kubernetes go client module maps all stable versions vx.y.z since 1.17.z onto v0.y.z, such as v0.17.0. Until go module versioning starts working in the Kubernetes client, I personally consider this versioning concept to be unready for real-world consumption and only a non-proof of concept.

And that's probably the reason for the mass of rather useless trivial blog posts that just repeat one after another the same useless examples (there is a nice German proverb fitting perfectly the blogosphere: "albeit everything has been said, it hasn't yet been said by everybody").
