schnippi78/alertmanager repository overview

⁠alertmanager-dark

Prometheus Alertmanager⁠ with a built-in dark mode.

Upstream Alertmanager ships only a light UI, and since v0.33 the UI is a Vite bundle embedded in the Go binary — there's no theme toggle and no file to swap. This image wraps the stock Alertmanager with a tiny nginx reverse proxy that injects a dark stylesheet into the served HTML. No recompiling, so it stays version-independent.

⁠Usage

Drop-in replacement for prom/alertmanager — same ports, config path, storage path, flags and healthcheck endpoint:

docker run -d -p 9093:9093 \
  -v $PWD/alertmanager.yml:/etc/alertmanager/alertmanager.yml \
  schnippi78/alertmanager:0.33.1-dark
