Installing Golang in Alpine WSL

Install the Go language:

sudo apk add go
bash-5.1$ go
Go is a tool for managing Go source code.

        build       compile packages and dependencies
        clean       remove object files and cached files
        doc         show documentation for package or symbol

Add the GOPATH environment variable to your .bashrc.

In my case my username is wsl. And the Go binaries are installed by default in $HOME/go/bin. So in my .bashrc I add:

export GOPATH=/home/wsl/go/bin
export PATH=$PATH:/home/wsl/.local/bin:$GOPATH

If I want to install an example module I have in Github globally, these are the steps:

git clone https://github.com/AlexanderAllen/names names
cd names
go mod init alexanderallen/names
# This will download any dependencies the module needs.
go mod tidy
# Test the compiled custom module:
go run .
vigilant-yonath
# This will install the custom module globally to the GOPATH:
go install
# To see what's available in the global GOPATH:
echo $GOPATH
/home/wsl/go/bin
ls -la $GOPATH
total 2056
