docker-slack-discord-relay

This project is for those of you who have applications like Grafana, which can push notifications to a Slack server, but do not support Discord entirely. Discord has API ingestion calls for Slack (/slack on the webhook URL), but they do not always work exactly right depending on the calling application. This project solves this problem with a nice little docker container which listens on port 8888.

This relay also buffers requests and resends requests on failure, ensuring all notifications are pushed eventually if connectivity to the Discord API endpoint is lost.
