Dendrite Polylith

These are Docker images for a Dendrite polylith deployment, in which Dendrite components run in their own processes, or even on their own machines!

Compose files

There are sample docker-compose files in the docker folder of the Dendrite repository⁠:

• docker-compose.deps.yml which runs the Postgres and Kafka prerequisites
• docker-compose.polylith.yml which runs a polylith Dendrite deployment

Configuration

The docker-compose files refer to the /etc/dendrite volume within the Docker container as where the runtime config should come from. The mounted folder must contain:

• dendrite.yaml configuration file (based on the sample dendrite-config.yaml in the docker/config folder in the Dendrite repository⁠
• matrix_key.pem server key, as generated using cmd/generate-keys
• server.crt certificate file
• server.key private key file for the above certificate

To generate keys:

go run github.com/matrix-org/dendrite/cmd/generate-keys \
  --private-key=matrix_key.pem \
  --tls-cert=server.crt \
  --tls-key=server.key
