[Tatsujinichi]

What version of Go are you using (go version)?

go version go1.13.6 linux/amd64

Does this issue reproduce with the latest release?

yes

What operating system and processor architecture are you using (go env)?

4.15.0-74-generic #84-Ubuntu SMP Thu Dec 19 08:06:28 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

What did you do?

private gitlab repo, accessible only through ssh, via non-standard port
go get will continue to try to use port 22

Because you can not specify a port anywhere besides the .gitconfig using url insteadOf
There is no nice way around this.
I tried using the port in GOPRIVATE envvar, but no good.

I expect that "go get" would allow me to specifying a port. Right now that is not allowed.

What did you do?

In that section of the issue report, please describe the specific commands that you executed in enough detail that we can reproduce the problem you're having. A general description is usually not sufficient.

Note that you can specify a port in your global .gitconfig. Beyond that, if you want to customize the way that the go command resolves an import path to a repo location and protocol, you'll need to use an HTTPS server as described in https://tip.golang.org/cmd/go/#hdr-Remote_import_paths.

At this time, we are not likely to add further customization points beyond that protocol. If you believe that you have a compelling use-case, please add an experience report describing it — and also describing why the existing alternatives are not suitable.
