Harbor-Exporter Overview

Secure your stack with a hardened Harbor-Exporter image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies.

Harbor-Exporter is the Prometheus metrics component for Harbor. It collects and exposes metrics about Harbor projects, registries, and health so you can monitor Harbor with Prometheus or compatible tooling.

Try It Out

Prerequisites

A running Kubernetes cluster (v1.21 or higher is recommended)
Helm v3.8 or higher for OCI support (Installation instructions)
kubectl installed and configured

Step 1: Start Cluster

If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions

Step 2: Add Repository to your Local Client

Add the Helm chart to your local Helm client.

helm repo add harbor https://helm.goharbor.io
helm repo update

Step 3: Create Namespace

Create a namespace:

kubectl create ns harbor

Step 4: Save Values File Locally

Save the file below as values.yaml

# Matches the port-forward target in Step 6 so Harbor generates correct URLs
externalURL: http://localhost:18080

nginx:
  image:
    repository: reg.mini.dev/harbor-nginx
    tag: latest

portal:
  image:
    repository: reg.mini.dev/harbor-portal
    tag: latest

core:
  image:
    repository: reg.mini.dev/harbor-core
    tag: latest

jobservice:
  image:
    repository: reg.mini.dev/harbor-jobservice
    tag: latest

registry:
  registry:
    image:
      repository: reg.mini.dev/harbor-registry
      tag: latest
  controller:
    image:
      repository: reg.mini.dev/harbor-registryctl
      tag: latest

database:
  internal:
    image:
      repository: reg.mini.dev/harbor-db
      tag: latest

trivy:
  enabled: true
  image:
    repository: reg.mini.dev/harbor-trivy-adapter
    tag: latest

redis:
  internal:
    image:
      repository: reg.mini.dev/harbor-redis
      tag: latest

metrics:
  enabled: true

exporter:
  image:
    repository: reg.mini.dev/harbor-exporter
    tag: latest

Render the chart locally with the overrides to confirm Minimus images will be deployed:

helm template harbor -f values.yaml harbor/harbor | grep "image:" | sort -u

Step 5: Deploy the Helm Chart

Deploy the Harbor Helm chart with the values.yaml file you saved in the previous step:

helm upgrade --install harbor -f values.yaml harbor/harbor -n harbor

Step 6: Verify Harbor-Exporter

Confirm the exporter pod is running and ready:

kubectl get pods -n harbor -l component=exporter

Port-forward the exporter service and check the metrics endpoint responds:

kubectl port-forward -n harbor svc/harbor-exporter 8001:8001

Run in another terminal:

curl -s http://127.0.0.1:8001/metrics | head

You should see Prometheus-style metric output.

Clean Up

helm uninstall harbor -n harbor
kubectl delete ns harbor

Technical Considerations

The Harbor-Exporter image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

Harbor-Exporter 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.
