Rollout strategy

[dvic]

Is there a way to use a 'recreate' rollout strategy? I have some deployments that acquire a lock on the database and therefore I can't have two or more instances running at the same time.

You may want to checkout the boot configuration which provides options for controlling the deployment strategy.

This only controls the deployment strategy across nodes, right? In my case I need to control the deployment strategy on a single node.

Since Kamal automatically boots a new container for zero-downtime deployments, a possible workaround for your situation would be to run kamal app stop followed by kamal deploy. This process effectively recreates the application.

Alternatively, you could utilize the pre-deploy hook as a workaround to run kamal app stop.

Yes, that was what I was doing currently.

Ah of course, does this hook run on the server or locally from the machine where kamal deploy was run from?

Thanks for the help!
