This repository contains the various Helm charts maintained by Mastodon Renn (it's me), who apparently decided they were k8s-savvy enough (after one (1) week of sleepless nights trying to migrate their home infrastructure) to tackle this problem. Anyways, see the Github project for the roadmap I have in mind.
The charts are published to a Github Helm repository. You can install or update it using the following command: help repo add mastodon https://gjorando.github.io/helm-charts --force-update
. Once this is done, use helm search repo mastodon
to look into the repository.
