So from our last article, we needed to move from Travis CI as our deployment mechanism to something faster and more efficient and Github Web-hooks came to mind. What are webhooks?
Webhooks allow you to build or set up GitHub Apps which subscribe to certain events on GitHub.com. When one of those events is triggered, we’ll send a HTTP POST payload to the webhook’s configured URL.
So when we make a commit or merge anything a payload is instantly sent out to the webhook configured URL. No delays, Nothing.
Install git…
After you’ve installed git, make sure it’s a relatively new version
$ git --versionSetup git (optionally if you haven’t do so)
$ git config --global user.name "Server"$ git config --global user.email "[email protected]"Create an ssh directory for the apache user
$ sudo mkdir /var/www/.ssh$ sudo chown -R www-data:www-data /var/www/.ssh/Generate a deploy key for apache user
$ sudo -Hu www-data ssh-keygen -t rsa
$ sudo cat /var/www/.ssh/id_rsa.pubAdd the SSH key to your user
- https://github.com/settings/ssh
- Create a new key
- Paste the deploy key you generated on the server
