In Show HN: Canine – A Heroku alternative built on Kubernetes
josegonzalez·May 15, 2022
Dokku maintainer here: Docker updates are usually the stressful ones, not Dokku (I try to call out all deprecations/changes in our Migration guides[1]). You can turn on Docker live-restore[1] to make Docker upgrades safer. I'd imagine the reason you have crashes is due to not having enough system resources (usually memory) to run your workloads. There isn't too much Dokku can do about that, though I would have loved to see a ticket or something on our chat venues to help debug. Dokku also supports kubernetes[3] if you still want the Dokku experience, and you can deploy images built in CI[4]. Glad to hear you have a setup that works for you though :) [1] Upgrading Dokku through different versions: https://dokku.com/docs/getting-started/upgrading/#migration-...

Dokku maintainer here: There are both Kubernetes[1] and Nomad[2] plugins. I'm also building schedulers for AWS Lambda, Compose (which I guess also sorta provides Azure ACI and AWS ECS support), and Swarm. You can also scale individual process types (so anything in your Procfile) via our `ps` plugin[3]. All plugins should support this, so you don't need to learn a new set of commands for alternative schedulers. - [1] Kubernetes Scheduler Plugin: https://github.com/dokku/dokku-scheduler-kubernetes - [2] NomadScheduler Plugin: https://github.com/dokku/dokku-scheduler-nomad - [3] Process Management: https://dokku.com/docs/processes/process-management/

Dokku maintainer here: There is a tutorial for using it. It's linked to after you install it for the first time, and is available here[1]. It goes through a few common tasks, though by no means is a "kitchen sink" tutorial. In regards to your specific questions: - I've answered this elsewhere, but your uptime is defined by your host uptime (and any mechanisms for backup/restore you have setup). Some hosting providers (AWS/GCP) provide migration of hosts that die, some have block storage (Azure/AWS/DO/GCP), while others (Rackspace) provide backups of specific directories. As with anything you run and maintain, very heavy YMMV here, but I'm happy to answer questions[2] specific to your needs. - Dokku runs very few/no persistent binaries (atm only an optional event-listener that restarts apps if it detects a web container has changed

it's IP address), so the attack vectors are your app and anything else you are running that exposes ports externally (SSH is the big one). I defer to others on container security, but our default Herokuish (and Pack) images are built to run processes as non-root users, so that should provide _some_ level of isolation. Container security is a big space, so I don't want to write something here that will be outdated in three seconds or is just plain wrong. If you have concerns about specific things in the project, please get in touch[2]. - I've used metadataproxy[3] to lock down IAM roles on a per-app basis (with a custom plugin injecting the correct container env var for each app). If you need to lock apps to specific users, there is the community dokku-acl[4] plugin. I'm also working on team management support in Dokku Pro[5] which will be a bit more familiar to users of Heroku. - I know of a few users using our kubernetes plugin[6] (automated via terraform) against mostly default Kubernetes clusters in Digitalocean and AWS. If the Dokku host dies, they just lose the ability to deploy, but can restore access fairly quickly. Everything else just kinda lives out there on their cluster. Feel free to reach out[1] and I'll try and answer any specific concerns :) - [1] Official tutorial: https://dokku.com/docs/deployment/application-deployment/ - [2] Ways to get in touch: https://dokku.com/docs/getting-started/where-to-get-help/ - [3] metadataproxy: https://github.com/lyft/metadataproxy - [4] dokku-acl: https://github.com/dokku-community/dokku-acl - [5] Dokku Pro: https://pro.dokku.com/ - [6] Kubernetes Scheduler plugin: https://github.com/dokku/dokku-scheduler-kubernetes

Re: Dokku, reports of our demise are greatly exaggerated. We're still chugging along, and have recently added Cloud Native Buildpacks support[1], as well as integrations with Kubernetes[2] and Nomad[3]. Happy to hear where you found out that development on the project was halted, given that I made a release yesterday[4]...

I have tried k3s and microk8s. Recently setup ArgoCD, connected to our GitLab instance. Tried both Traefik and Nginx Ingress controllers. And so on. And dokku is better if you want a PaaS. There are probably dokku/heroku/deis-like things that run on kubernetes, but so far I haven't found 'it'. Of course you can just run dokku on any k8s distribution. You can even use k8s as a backend for dokku instead of docker - https://github.com/dokku/dokku-scheduler-kubernetes

I really like git push workflows (Heroku / Dokku). I would use https://github.com/dokku/dokku-scheduler-kubernetes , but it doesn't support Dockerfiles, and I need Dockerfiles for a few of the applications that I want to run. It would be great if there were some docs on how to integrate Hyscale with, for example, a Github action to enable enable deployment on a push to master. It wouldn't be too difficult for me to set up, but having a "right way" to do it written by the maintainers would give me much more confidence.

If you have only one production server, dokku is "A docker-powered PaaS that helps you build and manage the lifecycle of applications." Dokku supports Heroku buildpack deployment (buildstep), Procfiles, Dockerfile deployment, Docker image deployment, git deployment (gitreceive), or tarfile deployments. https://github.com/dokku/dokku There are a number of plugins for Dokku. Dokku ships with the nginx plugin as the HTTP frontend proxy. Dokku supports SSL certs with the certs plugin. When you need to move to more than one server, what do you do? There's now a dokku-scheduler-kubernetes plugin which can do HA (high availability) which is worth reading about before you develop and document your own deployment workflow. https://github.com/dokku/dokku-scheduler-kubernetes I also always put build, test, and deployment commands in a Makefile.
