PM2 notes

Passing Environment Variables

Create a file called process.json with the following contents

{
  "apps" : [{
    "name"        : "my-app",
    "script"      : "v1/app.js",
    "env": {
        "VERSION": 1.0.0
     }
  }]

}

Now run the app as follows

pm2 start process.json

The variable process.env.VERSION will now be available inside your nodejs application and will be set to the value 1.0.0
