goproxy [-listen [host]:port] [-cacheDir /tmp]

goproxy serves the Go module proxy HTTP protocol at the given address (default 0.0.0.0:8081). It invokes the local go command to answer requests and therefore reuses the current GOPATH's module download cache and configuration (GOPROXY, GOSUMDB, and so on).

While the proxy is running, setting GOPROXY=http://host:port will instruct the go command to use it. Note that the module proxy cannot share a GOPATH with its own clients or else fetches will deadlock. (The client will lock the entry as “being downloaded” before sending the request to the proxy, which will then wait for the apparently-in-progress download to finish.)
