Karma-FIPS Overview

Secure your stack with a FIPS-validated, hardened Karma image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Karma is a dashboard for Prometheus Alertmanager. It fills the gaps in Alertmanager's own UI, aggregating alerts from one or more Alertmanager instances into a single view with grouping, silence management, alert history, and multi-grid layouts. Use this image when you need to meet the requirements for FIPS-validated cryptographic protection.

FIPS 140-3 Certification

This image is FIPS-validated to ensure its cryptographic operations meet the Federal Information Processing Standards (FIPS) required for secure government and regulated environments. Its core cryptographic modules are validated under the NIST Cryptographic Module Validation Program (CMVP) and comply with the FIPS 140-3 standard.

To verify that the FIPS 140-3 provider is configured and active, follow the instructions in the FIPS compliance tab.

Try It Out

For a quick test, run Karma against an Alertmanager instance.

Create a shared network so the containers can reach each other by name:

docker network create karma-net

Create a simple Alertmanager configuration file. Save it as alertmanager.yml in your current working directory.

global:
  resolve_timeout: 10m

route:
  receiver: 'example-webhook'        # A default receiver is required
  group_by: ['alertname']
  group_wait: 1s
  group_interval: 1m
  repeat_interval: 1h

receivers:
  - name: 'example-webhook'
    webhook_configs:
      - url: 'http://example.com/hook'

Set the file permissions to make the file readable by the container's non-root user:

chmod 644 alertmanager.yml

Start Alertmanager on the network, advertising itself as alertmanager so Karma can reach it by name:

docker run -d --rm --name alertmanager --network karma-net \
  -v ./alertmanager.yml:/etc/alertmanager/alertmanager.yml \
  reg.mini.dev/prometheus-alertmanager-fips

Run Karma on the same network, pointed at the Alertmanager instance:

docker run --rm --network karma-net \
  -p 8080:8080 \
  -e ALERTMANAGER_URI=http://alertmanager:9093 \
  reg.mini.dev/karma-fips

Visit the dashboard at http://localhost:8080.

Technical Considerations

The Karma-FIPS image provided by Minimus is a FIPS-validated, slim, security-hardened alternative to the public image.

Karma-FIPS built by Minimus:

Runs as non-root by default for a security-first approach that protects against privilege escalation attacks.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
