How well does Dokku support running on ARM?

• josegonzalez 2y ago
  I dropped armhf (32 bit arm) a few releases ago. It was painful to maintain and the few users of that were older Raspberry PI installs. I think there are other tools out there that better support low-powered platforms (piku comes to mind). ARM64 should be fine, with some caveats: - Dockerfile/nixpacks support is great! Just make sure your base images and your Dockerfile supports ARM64 building - Herokuish _works_ but not really. Most Heroku v2a buildpacks target AMD64. This is slowly changing, but out of the box it probably won't build as you expect. - CNB Buildpacks largely don't support ARM64 yet. Heroku _just_ added ARM64 support in heroku-24 (our next release switches to this) but again, there is work on the buildpacks to get things running. I run Dokku on ARM64 locally (a few raspberry pis running things under k3s) and develop Dokku on my M1 Macbook, so I think if there are any issues, I'd love to hear about them. Disclaimer: I am the Dokku maintainer.

    While ago I couldn't get LetsEncrypt working properly, was very frustrating. I think I just gave up at some point
