Docker Matrix Bootstrap for Synology Diskstations

This project consists of a script to bootstrap a Matrix Synapse Server, an Element Webapp and a Postgresql Server based on Docker Containers. It is specificly designed to work on a baremetal Synology Diskation NAS and will not work in any other environments!

Supported Environments

Baremetal Synology Diskstations with Docker support.

Other environments (even if its inside a VM on a Synology Diskstation) are not supported and will result in a broken configuration.

Precondition

The script expects (Let's Encrypt) certificates registered in Synology's certificate manager for:

• SYNAPSE_SERVER_NAME
• ELEMENT_SERVER_NAME (if ELEMENT_ENABLED=yes)

It will detect certificates either registered to a sub domain or wildcard domain.

Make sure to have seperate sub domains for Synapse and Element, as running them using the same sub domain is a potential security risk. The Script will aboard the preparation step if both sub domains are identical!

How to use

1. clone git project
2. edit variables in config
3. execute sudo ./run.sh prepare; only proceed with step 4 if no ERROR message occoured, otherwise the configuration will be broken!
4. execute sudo ./run.sh up -d
5. register user

• from cli: docker exec -ti matrix_synapse_1 register_new_matrix_user -c /data/homeserver.yaml http://localhost:8008
• from self-hosted Element: https://${ELEMENT_PUBLIC_BASEURL}/#/register (if ELEMENT_ENABLED=yes)

6. login user in self-hosted Element: https://${ELEMENT_PUBLIC_BASEURL}/#/login(if ELEMENT_ENABLED=yes)

If ELEMENT_ENABLED is not yes, Element will not be deployed and you will have to use another client!

run.sh wraps calls to docker-compose, by rendering the variables into the docker-compose.template on the fly and uses the result with docker-compose. The run.sh script passes all options and parameters to docker-compose... Thus, whatever works with docker-compose directly, does work with it as well.

Clean up

To perform a clean start, just run sudo ./run.sh clean. As a result the bind-mount source folders and the reverse proxy rules will be deleted. Make sure to recreate the folders and config using sudo ./run.sh prepare before running sudo ./run.sh up -d again.

Write docker-compose.yml to disk

If you choose to only use the script to bootstrap the initial configuration, you can run sudo ./run.sh write-compose to persist the generated docker-compose.yml to disk and use it with docker-compose.

What does the prepare step do?

Basicly it creates and configures everything required to run the Matrix Synapse server:

1. It creates data folders for Matrix Synapse, Element and Postgresql and fixes file permissions
2. It generate a homeserver.yml, gathers instance unique information from it and renders a configured homeserver.yml
3. It creates a domain specific log configuration for Matrix Synapse and uses it in homeserver.yml
4. It generates an Element config.json
5. It creates a seperate reverse-proxy configuration for Synapse and Element

The actions for Element are only performed, if ELEMENT_ENABLED is set to yes in config.

Though, it does not start the containers... this is done by executing sudo ./run.sh up -d.
