MetalLB Speaker Overview
Secure your stack with a hardened MetalLB Speaker 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.
MetalLB is a load-balancer implementation for bare metal Kubernetes clusters. The Speaker is deployed as a DaemonSet on every node and is responsible for advertising load-balancer IPs to the network using ARP/NDP for Layer 2 mode or BGP for Layer 3 mode.
Try It Out
Prerequisites
- A running Kubernetes cluster (v1.21 or higher is recommended)
- Helm v3.8 or higher for OCI support (Installation instructions)
kubectlinstalled 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 metallb https://metallb.github.io/metallb
helm repo updateStep 3: Deploy via Helm Chart
helm install metallb metallb/metallb \
--namespace metallb-system \
--create-namespace \
--set speaker.image.repository=reg.mini.dev/metallb-speaker \
--set speaker.image.tag=latest \
--set speaker.image.pullPolicy=AlwaysCheck that all Pods are up and running:
kubectl get pods -n metallb-systemConfirm that Minimus images were deployed:
kubectl -n metallb-system describe pods | grep Image:Clean Up
Uninstall the chart to delete the namespace and its resources, including Pods, Deployments, Services, Secrets, ConfigMaps, etc.:
helm uninstall metallb -n metallb-system
kubectl delete secret minimus-registry -n metallb-systemTechnical Considerations
The MetalLB Speaker image provided by Minimus is a slim, security-hardened alternative to the public image. The images are largely interchangeable, with a few differences as noted below.
MetalLB Speaker built by Minimus:
- Runs as root to support required functions in alignment with the public image.
- Requires elevated network capabilities (
NET_RAW) and host network access to perform ARP/NDP announcements and BGP sessions. - 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.
