注意事项

• You might want to commit your node_modules folder (#622) or add the npm install command to the post-deploy section: "post-deploy" : "npm install && pm2 startOrRestart ecosystem.json --env production"
• Verify that your remote server has the permission to git clone the repository
• You can declare specific environment variable depending on the environment you want to deploy the code to. For instance to declare variables for the production environment, just add "env_production": {} and declare that variables.
• PM2 will look by default to ecosystem.json. So you can skip the options if it's the case
• You can embed the "apps" & "deploy" section in the package.json
• It deploys your code via ssh, you don't need any dependencies
• Process are initialized / started automatically depending on application name in ecosystem.json
• PM2-deploy repository is there: pm2-deploy
