First, you will need to enable the Go Modules feature and configure Go to use the proxy.
bash:
export GOPROXY=https://goproxy.io
Or
powershell:
$env:GOPROXY = "https://goproxy.io"
Now, when you build and run your applications, go will fetch dependencies via goproxy.io.
Note: This proxy can't fetch your private repos of course.
Private proxy
Started
./goproxy -listen=0.0.0.0:80 -cacheDir=/data
Use docker image
docker run -d -p80:8081 goproxy/goproxy
Use the -v flag to persisting the proxy module data (change cacheDir to your own dir):
docker run -d -p80:8081 -v cacheDir:/go goproxy/goproxy
