dendrite

Dendrite Matrix Homeserver

Status: NOT PRODUCTION READY

About

This chart creates a monolith deployment, including an optionally enabled PostgreSQL dependency to connect to.

Manual database creation

(You can skip this, if you're deploying the PostgreSQL dependency)

You'll need to create the following database before starting Dendrite (see installation):

create database dendrite

or

sudo -u postgres createdb -O dendrite -E UTF-8 dendrite

Usage with appservices

Create a folder appservices and place your configurations in there. The configurations will be read and placed in a secret dendrite-appservices-conf.

Lower values result in easier admission of new cache entries but may also increase database load in comparison to higher values, so adjust conservatively. Higher values may make it harder for new items to make it into the cache, e.g. if new rooms suddenly become popular.

Monitoring

• Works well with Prometheus Operator (Helmchart) and their setup of Grafana, by enabling the following values:

dendrite_config:
  global:
    metrics:
      enabled: true

prometheus:
  servicemonitor:
    enabled: true
    labels:
      release: "kube-prometheus-stack"
  rules:
    enabled: true # will deploy alert rules
    labels:
      release: "kube-prometheus-stack"
grafana:
  dashboards:
    enabled: true # will deploy default dashboards

PS: The label release=kube-prometheus-stack is setup with the helmchart of the Prometheus Operator. For Grafana Dashboards it may be necessary to enable scanning in the correct namespaces (or ALL), enabled by sidecar.dashboards.searchNamespace in Helmchart of grafana (which is part of PrometheusOperator, so grafana.sidecar.dashboards.searchNamespace)
