Minimal Prometheus Image

Get It!

The image is available on cgr.dev:

docker pull cgr.dev/chainguard/prometheus-alertmanager:latest

Usage

This image comes with a default example config file at /etc/alertmanager/alertmanager.yml. The values from this example can be found in the Prometheus source tree.

The default command for this image uses that config file and sets a default storage path of /alertmanager. Both of these can be overridden with command line flags.

THe default port that alertmanager listens on is 9093. The web browser can be viewed locally over that port by mapping that in with -p 9093:9093.

To test:

% docker run -p 9093:9093 cgr.dev/chainguard/prometheus-alertmanager
