This chart is designed to make running Lemmy (https://join-lemmy.org/) easy on a kubernetes cluster.

This is mostly for experimental use by me. There are a number of things to improve, but for now I would consider this chart experimental.

To start, create the namespace you wish to install into, then create secrets for postgres credentials and pictrs keys:

kubectl create namespace lemmy

If postgres.enabled is set to true (default is false), we don't need to configure postgres credentials. Otherwise, run the following after filling in each parameter (user, password, host, and db):

kubectl create secret -n lemmy generic my-release-lemmy-postgres-creds \
    --from-literal=user= \
    --from-literal=password= \
    --from-literal=host= \
    --from-literal=db=

This is an example values.yaml that I use to run my test instance. I assume the disk space is inadequate at the moment, but lacking any definitive data requirements I have no better guess.

configuration:
  host: lemmy.dudeami.win
  adminUsername: "dudeami0"
  enableTLS: true

lemmy-ui:
  config:
    externalHost: lemmy.dudeami.win:443
    https: true
    debug: false

pictrs:
  storage:
    kind: "persistentVolumeClaim"
    pvc:
      storageClassName: "ceph-filesystem"
      size: 16Gi

postgres:
  enabled: true
  storage:
    kind: "persistentVolumeClaim"
    pvc:
      storageClassName: "ceph-filesystem"
      size: 8Gi

ingress:
  enabled: true
  className: nginx
  hosts:
    - lemmy.dudeami.win
  tls:
  - secretName: lemmy-dudeami-win-cert
    hosts:
      - lemmy.dudeami.win
  annotations:
    cert-manager.io/cluster-issuer: cluster-issuer

I'm new to lemmy so everything might not have been covered by this helm chart. I will actively help develop this chart for various usages. I would like to eventually support horizontal scaling via the postgres operator and figuring out a good way to horizontally scale lemmy instances.
