Set up a git webhook for your pm2 app in 5 minutes. Start, stop, or check the status of the webhook whenever you want. Use SSL verification if you need it.

Easy install

1. Install this module.

pm2 install jmensch1/pm2-git-hook

2. Specify a command to run when the hook fires.

Add a command to the env.githook section of your ecosystem.json file, for example:

apps:[{
  name: 'myApp',
  ...

  env: {
    githook: {
      command: 'git pull && npm install && pm2 restart myApp'
    }
  }
}]

3. Start the webhook server.

pm2 trigger pm2-git-hook start myApp

This will start an http server running on port 9000 that listens for push notifications from github. It will run the command in the cwd of your app whenever you push to master.

If you want to make sure server is working, run curl http://localhost:9000/status. Alternatively, run pm2 trigger pm2-git-hook status myApp, which simply executes the curl command.

4. Create the hook on github.

Go to Settings -> Webhook on github. Create a hook with payload URL http://{hostName}:9000/, content-type application-json, and no secret. Click Disable SSL Verification and then Add Webhook. Github will then ping the webhook server, and activate the hook.

Configurable Properties

Property	Description	Required	Default
command	The command to run when github sends a push notification.	true
branch	The branch to listen for pushes on.	false	master
port	The port to run the server on.	false	9000
protocol	http or https. Use https if you want SSL verification on your hook.	false	http
sslCertPath	the full path of your SSL cert	if protocol is https
sslKeyPath	the full path of your SSL private key	if protocol is https
secret	the webhook secret on github	if you create a webhook with a secret

Commands

1. pm2 trigger pm2-git-hook start myApp -- start the webhook server
2. pm2 trigger pm2-git-hook status myApp -- get a status report on the server
3. pm2 trigger pm2-git-hook stop myApp -- stop the webhook server

Notes

1. git credentials

If your command contains commands that require github credentials (e.g., git pull), the command will fail unless your server is set up to take the creds from the .git-credentials file, or from some other credentials helper program. You can use git config credential.helper store to create a .git-credentials file. (See here and here.)

2. multiple apps

You can run webhook servers for as many apps as you want. Just make sure the ports are different for each app.
