Getting dependencies via GOPROXY
I recently wanted to use a private registry in a go project.
It can be for many reasons:
- ensure immutability from one built to another
- ensure avaibility of a build (remember npm author who removed his library and broke half the internet?)
- get non-public library
How it works
Quick & Easy
It is super easy you just have to add an env variable:
You can then do a:
To see if it was applied.
Does it really work?
Then I was curious to know if it really worked or not?
I tried verbose but it wouldn’t show me the registry.
I then tried:
go get -v -t github.com/opentracing/opentracing-go@fakeversion
But it will give me an answer if a version doesn’t exist:
go get: github.com/opentracing/opentracing-go@fakeversion: invalid version: reading http://.com 404 Not found
This is what I was looking for:
go get -v -x <package>
It will show where it’s taken from:
$ go get -v -x # get https://myprivateregistry.com/github.com/@v/list # get https://myprivateregistry.com/github.com/gin-gonic/gin/@v/list # get https://myprivateregistry.com/github.com/gin-gonic/@v/list
