You can customize stacks for specific application instance by configuring stack services via environment variables. Go to
Instance > Stack, find a service you'd like to customize and click on a cogwheel icon.

To apply changes you must redeploy your stack.

- Build your own docker container image based in ours (
- Fork our stack
- Replace a service image to your in the template
- Deploy a new app with your custom stack
