> How Do You Handle Deployments?

This section misses the one thing I was interested in: how do you avoid downtime in a deployment?

I like to write web applications with Perl and Mojolicious, and a deployment is just "hypnotoad app", and then hypnotoad gracefully starts up new worker processes to handle new requests and lets the other ones exit once they've finished handling their in-flight requests.

When I switched to Docker I found that there was no good way to handle this.
