Tips & Tricks

Disabling federation

We're not sure this does it exactly and there is still a discussion running upstrem about whether this is the right way to do it & whether it could be more convenient. We welcome issues / change sets to close up more federation functionality.

• use DISABLE_FEDERATION=1 to turn off federation listeners
• don't use compose.matrix.yml in your traefik config to keep the federation ports closed

Enabling federation

See #27 for more.

Depending on your setup, using SERVE_SERVER_WELLKNOWN=true might work to start federating.

Seeing what changed in homeserver.yaml between versions

Change the version range to suit your needs.

git clone https://github.com/matrix-org/synapse
cd synapse/docs
git log --follow -p v1.48.0..v1.51.0 sample_config.yaml

Generating a new homeserver.yaml

The default is also available to see here.

docker run -it \
  --entrypoint="" \
  -e SYNAPSE_SERVER_NAME=foo.com \
  -e SYNAPSE_REPORT_STATS=no \
  matrixdotorg/synapse:v1.48.0 \
  sh -c '/start.py generate; cat /data/homeserver.yaml' > homeserver.yaml.tmpl`

Generating a new <server>.log.config

docker run -it \
  --entrypoint="" \
  -e SYNAPSE_SERVER_NAME=foo.com \
  -e SYNAPSE_REPORT_STATS=no \
  matrixdotorg/synapse:v1.48.0 \
  sh -c '/start.py generate; cat /data/foo.com.log.config' > log.config

Getting client discovery on a custom domain

You'll need to deploy something like this.

This could be implemented in this recipe but we haven't merged it in yet. Change sets are welcome.

Telegram bridging

WIP

Setting it up is a bit of a chicken/egg & chasing cats moment.

You need to get your bot setup on the telegram side first and have these values:

api_id: ...
api_hash: ...
telegram_bot_token: ...

Here is a rough guide:

abra app secret insert <domain> telegram_api_hash v1 <secret>
abra app secret insert <domain> telegram_bot_token v1 <secret>
abra app secret generate -a <domain>

abra app deploy <domain>
abra app run matrix.fva.wtf telegram_bridge cat /data/registration.yaml
abra app undeploy <domain>

abra app secret rm <domain> telegram_as_token
abra app secret insert <domain> telegram_as_token v1 <secret>

abra app secret rm <domain> telegram_as_token
abra app secret insert <domain> telegram_hs_token v1 <secret>

abra app deploy <domain>
