Installing Dendrite using Helm

To install Dendrite using the Helm chart, you first have to add the repository using the following commands:

helm repo add dendrite https://matrix-org.github.io/dendrite/
helm repo update

Next you’ll need to create a values.yaml file and configure it to your liking. All possible values can be found here, but at least you need to configure a server_name, otherwise the chart will complain about it:

dendrite_config:
  global:
    server_name: "localhost"

If you are going to use an existing Postgres database, you’ll also need to configure this connection:

dendrite_config:
  global:
    database:
      connection_string: "postgresql://PostgresUser:PostgresPassword@PostgresHostName/DendriteDatabaseName"
      max_open_conns: 90
      max_idle_conns: 5
      conn_max_lifetime: -1

Installing with PostgreSQL

The chart comes with a dependency on Postgres, which can be installed alongside Dendrite, this needs to be enabled in the values.yaml:

postgresql:
  enabled: true # this installs Postgres
  primary:
    persistence:
      size: 1Gi # defines the size for $PGDATA

dendrite_config:
  global:
    server_name: "localhost"

Using this option, the database.connection_string will be set for you automatically.
