The compiled protobufs are version controlled and you won't normally need to re-compile them when building Prometheus.

If however you have modified the defs and do need to re-compile, run ./scripts/genproto.sh from the parent dir.

In order for the script to run, you'll need protoc (version 3.5) in your PATH, and the following Go packages installed:

  • github.com/gogo/protobuf
  • github.com/gogo/protobuf/protoc-gen-gogofast
  • github.com/grpc-ecosystem/grpc-gateway/protoc-gen-grpc-gateway/
  • github.com/grpc-ecosystem/grpc-gateway/protoc-gen-swagger
  • golang.org/x/tools/cmd/goimports
