Usage

GitHub Action

You can use this image in a GitHub Action to generate the code for your proto files:

name: ProtocDock

on: [push]

jobs:
  compile:
    runs-on: ubuntu-latest

    steps:
    - name: ProtocDock Compile
      uses: valentin-kaiser/protocdock@master
      with:
        command: 'cd proto && rm -r ./gen/ && mkdir -p ./gen/ && protoc generic.proto --plugin=ts-protoc-gen=$PROTOC_GEN_TS_PATH --go_out=./gen/ --go-grpc_out=./gen/ --js_out="import_style=commonjs,binary:./gen/" --grpc-web_out="import_style=typescript,mode=grpcweb:./gen/" --proto_path=/app/proto'
        commit_message: '[GEN] Updated compiled proto definitions'

Docker

Pull the container:

docker pull ghcr.io/valentin-kaiser/protocdock:latest

Run the container via compose and enter the container:

docker compose up -d
docker exec -it proto-compiler /bin/bash

The compose maps a volume to the proto folder in the root of this repository. You can now run the protoc command to compile your proto files.

protoc generic.proto --plugin=ts-protoc-gen=$PROTOC_GEN_TS_PATH --go_out=./gen/ --go-grpc_out=./gen/ --js_out="import_style=commonjs,binary:./gen/" --grpc-web_out="import_style=typescript,mode=grpcweb:./gen/" --proto_path=/app/proto

Different versions

To use a different version of the compiler or a plugin, you have to build the image yourself. You can do this by running the following command in the root of this repository:

docker build -t protocdock:latest --build-arg <argument>=<version>  .

The available version arguments are:
