really/node-pm2-git

Docker container to fetch code from public/private repos with key where needed

Launch a git hosted node project with something like:

docker run -d -p 8080:8080 \
  --env NPM_TOKEN=aaaaaaaa-bbbb-0000-0a0a-ffffeeee8888 \
  --env PACKAGES="make gcc g++ python" \  
  --env REPO_KEY="$(cat ~/.ssh/my-repo-key)" \
  --env REPO="[email protected]:reallyreally/node-expressjs-service.git" \
  --env GIT_BRANCH="production-live" \
  --env KEYMETRICS_PUBLIC=0000aaaa1111ffff \
  --env KEYMETRICS_SECRET=0123456789abcdef \
  --env PORT=8080 \
  really/node-pm2-git ./pm2.json

Environment variables

NPM_TOKEN allows to use private npmjs.com packages (optional) PACKAGES allows installation of packages that might be needed for your app (optional) REPO_KEY read in a file to be used as the key for your repository clone (optional) REPO the repository to clone (required) GIT_BRANCH the branch to clone (optional) KEYMETRICS_PUBLIC & KEYMETRICS_SECRET if you use keymetrics.io (optional)

App Startup

In the example we call ./pm2.json which could contain the below.

{
  "apps": [{
    "name": "node-expressjs-service",
    "script": "./bin/www",
    "instances" : 0,
    "exec_mode" : "cluster",
    "post_update": ["npm install", "echo Launching..."],
    "env": {
      "production": true
    }
  }]
}

If you do not want to use ./pm2.json You equally could just replace it with ./bin/www for a typical ExpressJS application (you will loose the ability to configure PM2 clustering etc).
