protoc-gen-doc

This is a documentation generator plugin for the Google Protocol Buffers compiler (protoc). The plugin can generate HTML, JSON, DocBook, and Markdown documentation from comments in your .proto files. There is a Docker image available (docker pull pseudomuto/protoc-gen-doc) that has everything you need to generate documentation from your protos. The plugin is invoked by passing the --doc_out, and --doc_opt options to the protoc compiler. The docker image has two volumes: /out and /protos which are the directory to write the documentation to and the directory containing your proto files. By default HTML documentation is generated in /out/index.html for all .proto files in the /protos volume. This can be changed by passing the --doc_opt parameter to the container.
