Switch and go live

After the health checks pass, the engine changes the routes, marks the deploy live and stops the old instances.

All the new instances passed the health check. After this point, the deploy cannot go back.

1 / 5

After the health check passes, the deploy cannot go back. A cancel after the switch gets a refusal.

The order matters

The engine marks the deploy live before it stops the old instances. If the server stops during the drain, it comes back with the new deploy.

The change of routes and the wait of 2 seconds apply to web services and static sites. Other services have no route.

Deploy log

==> Your service is live 🎉

The URLs of the service come after this line.

The health check

The engine tests each new instance each second until it passes or the timeout ends.

Clean up

After each deploy, the engine deletes the old images, uploads and build folders of the service.
