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:
|
|
|
|
- [matrixdotorg/dendrite-monolith](https://hub.docker.com/r/matrixdotorg/dendrite-monolith) for monolith deployments
|
|
- [matrixdotorg/dendrite-polylith](https://hub.docker.com/r/matrixdotorg/dendrite-polylith) for polylith deployments
|
|
|
|
## 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`](https://github.com/matrix-org/dendrite/blob/main/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`](https://github.com/matrix-org/dendrite/blob/main/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`.
