Docker images

These are Docker images for Dendrite!

They can be found on Docker Hub:

Dockerfiles

The Dockerfile builds the base image which contains all of the Dendrite components. The Dockerfile.component file takes the given component, as specified with --buildarg component= from the base image and produce smaller component-specific images, which are substantially smaller and do not contain the Go toolchain etc.

Compose files

There are three sample docker-compose files:

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

Configuration

The docker-compose files refer to the /etc/dendrite volume 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

Starting Dendrite as a monolith deployment

Create your config based on the dendrite.yaml configuration file in the docker/config folder in the Dendrite repository. Additionally, make the following changes to the configuration:

  • Enable Naffka: use_naffka: true

Once in place, start the PostgreSQL dependency:

docker-compose -f docker-compose.deps.yml up postgres

Wait a few seconds for PostgreSQL to finish starting up, and then start a monolith:

docker-compose -f docker-compose.monolith.yml up

Starting Dendrite as a polylith deployment

Create your config based on the dendrite.yaml configuration file in the docker/config folder in the Dendrite repository.

Once in place, start all the dependencies:

docker-compose -f docker-compose.deps.yml up

Wait a few seconds for PostgreSQL and Kafka to finish starting up, and then start a polylith:

docker-compose -f docker-compose.polylith.yml up

Building the images

The docker/images-build.sh script will build the base image, followed by all of the component images.

The docker/images-push.sh script will push them to Docker Hub (subject to permissions).

If you wish to build and push your own images, rename matrixdotorg/dendrite to the name of another Docker Hub repository in images-build.sh and images-push.sh.
