Matrix alerts

Send kwatch incident alerts to Matrix. Use the interactive manager for installation and credential setup. This page explains the provider fields and shows a minimal configuration fragment.

Before you start, have these values ready:

• homeServer — HomeServer URL.
• accessToken — Access token.
• internalRoomId — Room ID.

For a guided setup, use the Matrix channel guide.

Credentials, tokens, keys, passwords, and webhook URLs must be mounted from a Kubernetes Secret. Use an exact ${file:/absolute/path} reference for every field marked Secret.

Configuration

homeServer	string	yes	no	url	—	HomeServer URL
accessToken	string	yes	yes	—	—	Access token
internalRoomId	string	yes	no	—	—	Room ID
title	string	no	no	—	—	Custom title

Minimal example

Add routes, retry, and fallback when you need delivery filtering or recovery. See the channels overview for guidance, or the complete provider reference for the catalog-wide view.
