Multi-stage Docker builds (#2850)
This builds on @S7evinK's work to make multi-stage Docker builds. Now
that we can build SQLite without Cgo this should be much simpler and
should make Docker builds in CI significantly faster.

Docker images

These are Docker images for Dendrite!

They can be found on Docker Hub:

Dockerfiles

The Dockerfile is a multistage file which can build all four Dendrite images depending on the supplied --target. From the root of the Dendrite repository, run:

docker build . --target monolith -t matrixdotorg/dendrite-monolith
docker build . --target polylith -t matrixdotorg/dendrite-monolith
docker build . --target demo-pinecone -t matrixdotorg/dendrite-demo-pinecone
docker build . --target demo-yggdrasil -t matrixdotorg/dendrite-demo-yggdrasil

Compose files

There are three sample docker-compose files:

  • 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 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 as a monolith deployment

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

Then start the deployment:

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

Starting Dendrite as a polylith deployment

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

Then start the deployment:

docker-compose -f docker-compose.polylith.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.
