Dokku maintainer here. The catch you mentioned has a few caveats: - You can host the data for the install on a mounted volume, and replace the underlying instance at will (if you're using something like AWS or GCP). - We support alternative schedulers (Kubernetes and Nomad, with others like Compose, Lambda, and Swarm coming soon). In the case of using an alternate scheduler, your apps won't go down if the build server goes down. - Since it is self-hosted, your Dokku install's uptime is pegged to your infrastructure's uptime. So yeah, if you are installing it on a Raspberry PI whose uptime is decided by a light switch that is next to your kitchen and you accidentally switch it off every once in a while due to not being able to see the switch at night (very specific example, I know), then yeah, you'll be down for a little while.
