conduwuit for Docker

Docker

To run conduwuit with Docker you can either build the image yourself or pull it from a registry.

Use a registry

OCI images for conduwuit are available in the registries listed below.

Registry	Image	Size	Notes
GitHub Registry	ghcr.io/girlbossceo/conduwuit:latest		Stable tagged image.
GitLab Registry	registry.gitlab.com/conduwuit/conduwuit:latest		Stable tagged image.
Docker Hub	docker.io/girlbossceo/conduwuit:latest		Stable tagged image.
GitHub Registry	ghcr.io/girlbossceo/conduwuit:main		Stable main branch.
GitLab Registry	registry.gitlab.com/conduwuit/conduwuit:main		Stable main branch.
Docker Hub	docker.io/girlbossceo/conduwuit:main		Stable main branch.

Use

docker image pull <link>

to pull it to your machine.

Run

When you have the image you can simply run it with

docker run -d -p 8448:6167 \
  -v db:/var/lib/conduwuit/ \
  -e CONDUWUIT_SERVER_NAME="your.server.name" \
  -e CONDUWUIT_DATABASE_BACKEND="rocksdb" \
  -e CONDUWUIT_ALLOW_REGISTRATION=false \
  --name conduit <link>

or you can use docker compose.

The -d flag lets the container run in detached mode. You may supply an optional conduwuit.toml config file, the example config can be found here. You can pass in different env vars to change config values on the fly. You can even configure conduwuit completely by using env vars. For an overview of possible values, please take a look at the docker-compose.yml file.

If you just want to test conduwuit 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
• If you don't have a traefik instance set up and would like to use it, use docker-compose.with-traefik.yml
• If you want a setup that works out of the box with caddy-docker-proxy, use docker-compose.with-caddy.yml and replace all example.com placeholders with your own domain
• For any other reverse proxy, use 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.

When picking the caddy-docker-proxy compose file, it's important to first create the caddy network before spinning up the containers:

docker network create caddy

After that, you can rename it so it matches docker-compose.yml and spin up the containers!

Additional info about deploying conduwuit can be found here.

Build

To build the conduwuit 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:

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:

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 (or docker-compose.with-traefik.yml) and docker-compose.override.yml, it is equally easy to deploy and use conduwuit, 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 conduwuit 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.
