Docker images

These are Docker images for Dendrite!

They can be found on Docker Hub:

matrixdotorg/dendrite-monolith for monolith deployments

Dockerfile

The Dockerfile is a multistage file which can build Dendrite. From the root of the Dendrite repository, run:

docker build . -t matrixdotorg/dendrite-monolith

Compose file

There is one sample docker-compose files:

docker-compose.yml which runs a Dendrite deployment with Postgres

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 one of the sample config files)
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:

docker run --rm --entrypoint="" \
  -v $(pwd):/mnt \
  matrixdotorg/dendrite-monolith:latest \
  /usr/bin/generate-keys \
  -private-key /mnt/matrix_key.pem \
  -tls-cert /mnt/server.crt \
  -tls-key /mnt/server.key

The key files will now exist in your current working directory, and can be mounted into place.

Starting Dendrite

Create your config based on the dendrite-sample.yaml sample configuration file.

Then start the deployment:

docker-compose -f docker-compose.yml up

Building the images

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

The build/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.
