Contributors App

Display GitHub contributors for a specific repo.

The Contributors App is designed to run in the scratch Docker image. The total size of the Docker image including the contributors binary is less than 6MB.

• Avoid "x509: failed to load system roots and no roots provided" by bundling root certificates.
• Avoid dynamic linking by using the pure Go net package (-tags netgo)
• Avoid dynamic linking by disabling cgo (CGO_ENABLED=0)
• Reduce binary size by omitting dwarf information (-ldflags '-w')
