This process is much simpler now. All you have to do is provide the required values per the Webhook, and it will be done for you.
- GitHub repository -> Settings
- Webhooks & Services
- AWS Opsworks
- Provide AWS::IAM keys, Stack and App ID , and branch you want to deploy.
Be aware that by this process you deploy a specific app to ALL the layers in a stack. This means that if you have custom layers with ruby, they will also deploy the specific app to those layers too. Useful for worker layer, however, increased deployment time when you have multiple rails apps in different layers.
Ensure that your user has proper permissions to deploy on the specific stack.
