hiveco/alertmanager repository overview

⁠Prometheus Alertmanager in a Container

Source code for hiveco/alertmanager⁠. This image is designed to be an extremely thin wrapper around the official prom/alertmanager image, providing support for supplying command line arguments in environment variables. See #504⁠ for details on why the Prometheus authors chose not to include this functionality in the official image.

Environment variables given to docker run that are prefixed with ALERTMGR_ are converted into command line arguments to Alertmanager. Underscores are converted to periods and double-underscores to dashes.

Examples:

• To set --log.level=error, add the option -e ALERTMGR_LOG_LEVEL=error
• To set --web.external-url=http://localhost:9093, add the option -e ALERTMGR_WEB_EXTERNAL__URL=http://localhost:9093.
