GolangInit.md

Create the server directory, and inside it a Dockerfile. It will install all the dev dependencies in a container :

FROM golang

WORKDIR /go/src/github.com/$GITHUB_USERNAME/grpctodo/server

RUN go install github.com/ramya-rao-a/go-outline@latest
RUN go install golang.org/x/tools/gopls@latest
RUN go install honnef.co/go/tools/cmd/staticcheck@latest
RUN go install github.com/go-delve/delve/cmd/dlv@latest

RUN go install github.com/silenceper/gowatch@latest

Once the docker file is ready, let's create the service in docker compose file (compose.yml). Add the following lines in the services part :

  server:
    build:
      dockerfile: ./server/Dockerfile
      # We set the context to the base direcotry to inject the certificates and the proto files
      context: ./
    # For mac m1 users only
    # platform: linux/amd64
    ports:
      # The local port on which the server will be avalaible
      - 4000:4000
    volumes:
      - ./dev/certs/grpctodo.dev+1-key.pem:/certs/key.pem:ro
      - ./dev/certs/grpctodo.dev+1.pem:/certs/cert.pem:ro
      - ./server:/go/src/github.com/$GITHUB_USERNAME/grpctodo/server
    # This is to keep the container running even when there is no process, only for initialization
    stdin_open: true

Spin up the containers :

docker-compose up -d

Initialize the go module

docker-compose exec server go mod init

If you see the go.mod file, we are ready to code.

At this point, I advise you to open VSCode or equivalent inside the container, as golang binairies are not on the host machine
