karma v0.1.0

Observability

Karma — a dashboard for Prometheus Alertmanager: aggregates alerts from multiple Alertmanager instances, groups and silences them, with a clean UI. Deployed as a single stateless host-networked Nomad service.

nomad-pack run karma --registry nomploy

…or one line (add registry + run)

curl -fsSL https://packs.nomploy.com/install.sh | sh -s -- karma

Needs nomad-pack on PATH. The script only adds the nomploy registry and runs this pack.

Readme

karma

Karma — a dashboard for Prometheus Alertmanager. It aggregates alerts from one or many Alertmanager instances, groups and deduplicates them, shows rich labels and annotations, and lets you create and manage silences from a clean, auto-refreshing UI — a much nicer view than Alertmanager's built-in page.

Single stateless host-networked Nomad service (no volume).

Deploy

nomad-pack registry add nomploy https://github.com/Nomploy/nomad-packs
nomad-pack run karma --registry=nomploy

Configure

Variable	Default	Description
`port`	`8080`	Web UI port (`PORT`).
`alertmanager_uri`	`http://127.0.0.1:9093`	Alertmanager URL to display (`ALERTMANAGER_URI`).
`image`	`ghcr.io/prymitive/karma:latest`	Container image. Pin a tag in production.
`resources`	`{ cpu = 300, memory = 256 }`	Task resources.

Pairs with alertmanager and monitoring. For multiple Alertmanagers or advanced options (auth, label rules), mount a karma.yaml and pass CONFIG_FILE. Being stateless, it needs no storage and can run anywhere it can reach your Alertmanager.
