Add a dockerfile for running a set of Synapse worker processes (#9162) This PR adds a Dockerfile and some supporting files to the `docker/` directory. The Dockerfile's intention is to spin up a container with: * A Synapse main process. * Any desired worker processes, defined by a `SYNAPSE_WORKERS` environment variable supplied at runtime. * A redis for worker communication. * A nginx for routing traffic. * A supervisord to start all worker processes and monitor them if any go down. Note that **this is not currently intended to be used in production**. If you'd like to use Synapse workers with Docker, instead make use of the official image, with one worker per container. The purpose of this dockerfile is currently to allow testing Synapse in worker mode with the [Complement](https://github.com/matrix-org/complement/) test suite. `configure_workers_and_start.py` is where most of the magic happens in this PR. It reads from environment variables (documented in the file) and creates all necessary config files for the processes. It is the entrypoint of the Dockerfile, and thus is run any time the docker container is spun up, recreating all config files in case you want to use a different set of workers. One can specify which workers they'd like to use by setting the `SYNAPSE_WORKERS` environment variable (as a comma-separated list of arbitrary worker names) or by setting it to `*` for all worker processes. We will be using the latter in CI. Huge thanks to @MatMaul for helping get this all working :tada: This PR is paired with its equivalent on the Complement side: https://github.com/matrix-org/complement/pull/62. Note, for the purpose of testing this PR before it's merged: You'll need to (re)build the base Synapse docker image for everything to work (`matrixdotorg/synapse:latest`). Then build the worker-based docker image on top (`matrixdotorg/synapse:workers`).

# Running tests against a dockerised Synapse
It's possible to run integration tests against Synapse
using [Complement](https://github.com/matrix-org/complement). Complement is a Matrix Spec
compliance test suite for homeservers, and supports any homeserver docker image configured
to listen on ports 8008/8448. This document contains instructions for building Synapse
docker images that can be run inside Complement for testing purposes.
Note that running Synapse's unit tests from within the docker image is not supported.

SQLite-based Synapse deployment.
Start by building the base Synapse docker image. If you wish to run tests with the latest
release of Synapse, instead of your current checkout, you can skip this step. From the
root of the repository:
```sh
docker build -t matrixdotorg/synapse -f docker/Dockerfile .
```
This will build an image with the tag `matrixdotorg/synapse`.
Next, build the Synapse image for Complement.

As with the single-process image, build the base Synapse docker image. If you wish to run

This includes any desired Synapse worker processes, a nginx to route traffic accordingly,

Add a dockerfile for running a set of Synapse worker processes (#9162) This PR adds a Dockerfile and some supporting files to the `docker/` directory. The Dockerfile's intention is to spin up a container with: * A Synapse main process. * Any desired worker processes, defined by a `SYNAPSE_WORKERS` environment variable supplied at runtime. * A redis for worker communication. * A nginx for routing traffic. * A supervisord to start all worker processes and monitor them if any go down. Note that **this is not currently intended to be used in production**. If you'd like to use Synapse workers with Docker, instead make use of the official image, with one worker per container. The purpose of this dockerfile is currently to allow testing Synapse in worker mode with the [Complement](https://github.com/matrix-org/complement/) test suite. `configure_workers_and_start.py` is where most of the magic happens in this PR. It reads from environment variables (documented in the file) and creates all necessary config files for the processes. It is the entrypoint of the Dockerfile, and thus is run any time the docker container is spun up, recreating all config files in case you want to use a different set of workers. One can specify which workers they'd like to use by setting the `SYNAPSE_WORKERS` environment variable (as a comma-separated list of arbitrary worker names) or by setting it to `*` for all worker processes. We will be using the latter in CI. Huge thanks to @MatMaul for helping get this all working :tada: This PR is paired with its equivalent on the Complement side: https://github.com/matrix-org/complement/pull/62. Note, for the purpose of testing this PR before it's merged: You'll need to (re)build the base Synapse docker image for everything to work (`matrixdotorg/synapse:latest`). Then build the worker-based docker image on top (`matrixdotorg/synapse:workers`).

available (usually a running postgres docker container).
The `SYNAPSE_WORKER_TYPES` environment variable is a comma-separated list of workers to
use when running the container. All possible worker names are defined by the keys of the
`WORKERS_CONFIG` variable in [this script](configure_workers_and_start.py), which the
Dockerfile makes use of to generate appropriate worker, nginx and supervisord config
files.
Sharding is supported for a subset of workers, in line with the
[worker documentation](../docs/workers.md). To run multiple instances of a given worker
type, simply specify the type multiple times in `SYNAPSE_WORKER_TYPES`
(e.g `SYNAPSE_WORKER_TYPES=event_creator,event_creator...`).
Otherwise, `SYNAPSE_WORKER_TYPES` can either be left empty or unset to spawn no workers
(leaving only the main process). The container is configured to use redis-based worker
mode.
Logs for workers and the main process are logged to stdout and can be viewed with
standard `docker logs` tooling. Worker logs contain their worker name
