GOPROXY

A global proxy for go modules. see: https://goproxy.io

Requirements

It invokes the local go command to answer requests.
The default cacheDir is GOPATH, you can set it up by yourself according to the situation.

Build

git clone https://github.com/goproxyio/goproxy.git
cd goproxy
make

Started

Proxy mode

./bin/goproxy -listen=0.0.0.0:80 -cacheDir=/tmp/test

If you run go get -v pkg in the proxy machine, should set a new GOPATH which is different from the old GOPATH, or mayebe deadlock. See the file test/get_test.sh.

Router mode

./bin/goproxy -listen=0.0.0.0:80 -proxy https://goproxy.io

Use the -proxy flag switch to "Router mode", which implements route filter to routing private module or public module .

                                         direct
                      +----------------------------------> private repo
                      |
                 match|pattern
                      |
                  +---+---+           +----------+
go get  +-------> |goproxy| +-------> |goproxy.io| +---> golang.org/x/net
                  +-------+           +----------+
                 router mode           proxy mode

In Router mode, use the -exclude flag set pattern , direct to the repo which match the module path, pattern are matched to the full path specified, not only to the host component.

./bin/goproxy -listen=0.0.0.0:80 -cacheDir=/tmp/test -proxy https://goproxy.io -exclude "*.corp.example.com,rsc.io/private"

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

Docker Compose

docker-compose up

Appendix

1. set export GOPROXY=http://localhost to enable your goproxy.
2. set export GOPROXY=direct to disable it.
