Each server or group has what is known as a "Deploy Hook"; this is a URL that you add to Gitlab as a webhook so Deploy is notified when new commits are pushed to your repository and can start automatic deployments.
Getting the "Deploy Hook" URL for a server
- Firstly navigate to the "Servers and Groups" page via the Settings on a given Project page:
You can also access the page via the Servers box under a given project, inside the main Projects page:
- Next head to the edit page for the server:
- Find and make a note of he URL under the Automatic Deployment heading on the right hand side:
Adding a the "Deploy Hook" to GitHub
- Open your project up in Gitlab (there is a link to the top-left of the navigation for "Projects" in Gitlab), and navigate to the Settings tab, followed by the Integrations tab just below:
- Directly below paste your webhook URL into the URL field, ensure only Push events is checked under Trigger, then click Add webhook.
- That's it! With this set up Deploy and Gitlab will now work together to automatically push changes to your server.
Please note, if you're adding a self hosted Gitlab repository, you'll need to make sure you select the repository host as Gitlab in your general settings first.
Specifying a branch to deploy from
The automatic deployment process will check the branch configured for your server (Branch to Deploy from) each time a request is made to the webhook URL. If the branch is found to match, the deployment will be queued, otherwise it will be ignored. If you wish to change the branch, just navigate to your server settings in Deploy, then update the Branch to Deploy from found under Deployment Options.
