Simplify management by unifying projects using submodules in git

Unify

  1. Create a unified project

    mkdir ~/dev/parentProjectName && \
cd ~/dev/parentProjectName && \
git init && \
git submodule add git@github.com:orgName/projA.git projA && \
git submodule add git@github.com:orgName/projA.git projB

Why is my NodeJS process hanging in Docker?

Establish the directory structure

  • README.md
    • docker-compose.yml
    • worker/package.json
    • worker/src/utils.js
    • worker/src/sampleNodeProcess.js

Run the experiment

echo "###"
