# Deploy using Docker
|
|
|
|
> **Note:** To run and use Conduit you should probably use it with a Domain or Subdomain behind a reverse proxy (like Nginx, Traefik, Apache, ...) with a Lets Encrypt certificate.
|
|
|
|
## Docker
|
|
|
|
### Build & Dockerfile
|
|
|
|
The Dockerfile provided by Conduit has two stages, each of which creates an image.
|
|
|
|
1. **Builder:** Builds the binary from local context or by cloning a git revision from the official repository.
|
|
2. **Runner:** Copies the built binary from **Builder** and sets up the runtime environment, like creating a volume to persist the database and applying the correct permissions.
|
|
|
|
To build the image you can use the following command
|
|
|
|
```bash
|
|
docker build --tag matrixconduit/matrix-conduit:latest .
|
|
```
|
|
|
|
which also will tag the resulting image as `matrixconduit/matrix-conduit:latest`.
|
|
|
|
### Run
|
|
|
|
After building the image you can simply run it with
|
|
|
|
```bash
|
|
docker run -d -p 8448:6167 \
|
|
-v db:/var/lib/matrix-conduit/ \
|
|
-e CONDUIT_SERVER_NAME="your.server.name" \
|
|
-e CONDUIT_DATABASE_BACKEND="rocksdb" \
|
|
-e CONDUIT_ALLOW_REGISTRATION=true \
|
|
-e CONDUIT_ALLOW_FEDERATION=true \
|
|
-e CONDUIT_MAX_REQUEST_SIZE="20_000_000" \
|
|
-e CONDUIT_TRUSTED_SERVERS="[\"matrix.org\"]" \
|
|
-e CONDUIT_MAX_CONCURRENT_REQUESTS="100" \
|
|
-e CONDUIT_LOG="warn,rocket=off,_=off,sled=off" \
|
|
--name conduit matrixconduit/matrix-conduit:latest
|
|
```
|
|
|
|
or you can skip the build step and pull the image from one of the following registries:
|
|
|
|
| Registry | Image | Size |
|
|
| --------------- | --------------------------------------------------------------- | --------------------- |
|
|
| Docker Hub | [matrixconduit/matrix-conduit:latest][dh] | ![Image Size][shield] |
|
|
| GitLab Registry | [registry.gitlab.com/famedly/conduit/matrix-conduit:latest][gl] | ![Image Size][shield] |
|
|
|
|
[dh]: https://hub.docker.com/r/matrixconduit/matrix-conduit
|
|
[gl]: https://gitlab.com/famedly/conduit/container_registry/2497937
|
|
[shield]: https://img.shields.io/docker/image-size/matrixconduit/matrix-conduit/latest
|
|
|
|
The `-d` flag lets the container run in detached mode. You now need to supply a `conduit.toml` config file, an example can be found [here](../conduit-example.toml).
|
|
You can pass in different env vars to change config values on the fly. You can even configure Conduit completely by using env vars, but for that you need
|
|
to pass `-e CONDUIT_CONFIG=""` into your container. For an overview of possible values, please take a look at the `docker-compose.yml` file.
|
|
|
|
If you just want to test Conduit for a short time, you can use the `--rm` flag, which will clean up everything related to your container after you stop it.
|
|
|
|
### Docker-compose
|
|
|
|
If the `docker run` command is not for you or your setup, you can also use one of the provided `docker-compose` files.
|
|
|
|
Depending on your proxy setup, you can use one of the following files;
|
|
- If you already have a `traefik` instance set up, use [`docker-compose.for-traefik.yml`](docker-compose.for-traefik.yml)
|
|
- If you don't have a `traefik` instance set up (or any other reverse proxy), use [`docker-compose.with-traefik.yml`](docker-compose.with-traefik.yml)
|
|
- For any other reverse proxy, use [`docker-compose.yml`](docker-compose.yml)
|
|
|
|
When picking the traefik-related compose file, rename it so it matches `docker-compose.yml`, and
|
|
rename the override file to `docker-compose.override.yml`. Edit the latter with the values you want
|
|
for your server.
|
|
|
|
Additional info about deploying Conduit can be found [here](../DEPLOY.md).
|
|
|
|
### Build
|
|
|
|
To build the Conduit image with docker-compose, you first need to open and modify the `docker-compose.yml` file. There you need to comment the `image:` option and uncomment the `build:` option. Then call docker-compose with:
|
|
|
|
```bash
|
|
docker-compose up
|
|
```
|
|
|
|
This will also start the container right afterwards, so if want it to run in detached mode, you also should use the `-d` flag.
|
|
|
|
### Run
|
|
|
|
If you already have built the image or want to use one from the registries, you can just start the container and everything else in the compose file in detached mode with:
|
|
|
|
```bash
|
|
docker-compose up -d
|
|
```
|
|
|
|
> **Note:** Don't forget to modify and adjust the compose file to your needs.
|
|
|
|
### Use Traefik as Proxy
|
|
|
|
As a container user, you probably know about Traefik. It is a easy to use reverse proxy for making
|
|
containerized app and services available through the web. With the two provided files,
|
|
[`docker-compose.for-traefik.yml`](docker-compose.for-traefik.yml) (or
|
|
[`docker-compose.with-traefik.yml`](docker-compose.with-traefik.yml)) and
|
|
[`docker-compose.override.yml`](docker-compose.override.traefik.yml), it is equally easy to deploy
|
|
and use Conduit, with a little caveat. If you already took a look at the files, then you should have
|
|
seen the `well-known` service, and that is the little caveat. Traefik is simply a proxy and
|
|
loadbalancer and is not able to serve any kind of content, but for Conduit to federate, we need to
|
|
either expose ports `443` and `8448` or serve two endpoints `.well-known/matrix/client` and
|
|
`.well-known/matrix/server`.
|
|
|
|
With the service `well-known` we use a single `nginx` container that will serve those two files.
|
|
|
|
So...step by step:
|
|
|
|
1. Copy [`docker-compose.traefik.yml`](docker-compose.traefik.yml) and [`docker-compose.override.traefik.yml`](docker-compose.override.traefik.yml) from the repository and remove `.traefik` from the filenames.
|
|
2. Open both files and modify/adjust them to your needs. Meaning, change the `CONDUIT_SERVER_NAME` and the volume host mappings according to your needs.
|
|
3. Create the `conduit.toml` config file, an example can be found [here](../conduit-example.toml), or set `CONDUIT_CONFIG=""` and configure Conduit per env vars.
|
|
4. Uncomment the `element-web` service if you want to host your own Element Web Client and create a `element_config.json`.
|
|
5. Create the files needed by the `well-known` service.
|
|
|
|
- `./nginx/matrix.conf` (relative to the compose file, you can change this, but then also need to change the volume mapping)
|
|
|
|
```nginx
|
|
server {
|
|
server_name <SUBDOMAIN>.<DOMAIN>;
|
|
listen 80 default_server;
|
|
|
|
location /.well-known/matrix/server {
|
|
return 200 '{"m.server": "<SUBDOMAIN>.<DOMAIN>:443"}';
|
|
types { } default_type "application/json; charset=utf-8";
|
|
}
|
|
|
|
location /.well-known/matrix/client {
|
|
return 200 '{"m.homeserver": {"base_url": "https://<SUBDOMAIN>.<DOMAIN>"}}';
|
|
types { } default_type "application/json; charset=utf-8";
|
|
add_header "Access-Control-Allow-Origin" *;
|
|
}
|
|
|
|
location / {
|
|
return 404;
|
|
}
|
|
}
|
|
```
|
|
|
|
6. Run `docker-compose up -d`
|
|
7. Connect to your homeserver with your preferred client and create a user. You should do this immediately after starting Conduit, because the first created user is the admin.
|
|
|
|
|
|
|
|
|
|
## Voice communication
|
|
|
|
In order to make or receive calls, a TURN server is required. Conduit suggests using [Coturn](https://github.com/coturn/coturn) for this purpose, which is also available as a Docker image. Before proceeding with the software installation, it is essential to have the necessary configurations in place.
|
|
|
|
### Configuration
|
|
|
|
Create a configuration file called `coturn.conf` containing:
|
|
|
|
```conf
|
|
use-auth-secret
|
|
static-auth-secret=<a secret key>
|
|
realm=<your server domain>
|
|
```
|
|
A common way to generate a suitable alphanumeric secret key is by using `pwgen -s 64 1`.
|
|
|
|
These same values need to be set in conduit. You can either modify conduit.toml to include these lines:
|
|
```
|
|
turn_uris = ["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]
|
|
turn_secret = "<secret key from coturn configuration>"
|
|
```
|
|
or append the following to the docker environment variables dependig on which configuration method you used earlier:
|
|
```yml
|
|
- CONDUIT_TURN_URIS=["turn:<your server domain>?transport=udp", "turn:<your server domain>?transport=tcp"]
|
|
- CONDUIT_TURN_SECRET="<secret key from coturn configuration>
|
|
```
|
|
Restart Conduit to apply these changes.
|
|
|
|
### Run
|
|
Run the [Coturn](https://hub.docker.com/r/coturn/coturn) image using
|
|
```bash
|
|
docker run -d --network=host -v $(pwd)/coturn.conf:/etc/coturn/turnserver.conf coturn/coturn
|
|
```
|
|
|
|
or docker-compose. For the latter, paste the following section into a file called `docker-compose.yml`
|
|
and run `docker-compose up -d` in the same directory.
|
|
|
|
```yml
|
|
version: 3
|
|
services:
|
|
turn:
|
|
container_name: coturn-server
|
|
image: docker.io/coturn/coturn
|
|
restart: unless-stopped
|
|
network_mode: "host"
|
|
volumes:
|
|
- ./coturn.conf:/etc/coturn/turnserver.conf
|
|
```
|
|
|
|
