This project creates a containerized http endpoint which listens for requests by analertmanager webhook receiverand maps it to thesignal-cli by bbernhard.
This is useful if you already have the signal-cli running for example as ahome-assistant notifier.
Use a prometheus labelrecipients to specify where you want the signal message to be send.
It now supports alert webhooks from Grafana aswell, including a preview graph image!
docker run -d --name alertmanager-signal \ -p 10000:10000 \ -v$(pwd)/config.yaml:/config.yaml \ docker.io/schlauerlauer/alertmanager-webhook-signal:1.1.1Aconfig.yaml file is needed for configuration.
Example configuration:
