Kubearmor Overview

Secure your stack with a hardened Kubearmor 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.

KubeArmor is a cloud-native runtime security enforcement system that restricts the behavior of pods, containers, and nodes (VMs) at the system level, such as process execution, file access, and networking operations. It leverages Linux Security Modules (LSMs) such as AppArmor, SELinux, or BPF-LSM to enforce user-defined policies, and uses eBPF to generate rich alerts and telemetry tied to container, pod, and namespace identity.

Try It Out

KubeArmor can be deployed with a Helm chart.

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
A Linux kernel with AppArmor, SELinux, or BPF-LSM enabled for policy enforcement

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 kubearmor https://kubearmor.github.io/charts
helm repo update

Step 3: Deploy via Helm Chart

helm upgrade --install kubearmor kubearmor/kubearmor \
  -n kubearmor --create-namespace \
  --set kubearmor.image.repository=reg.mini.dev/kubearmor \
  --set kubearmor.image.tag=latest \
  --wait

Wait a minute and check that the Pods are up and running:

kubectl -n kubearmor get po

Confirm that the Minimus image was deployed:

kubectl -n kubearmor describe pods | grep Image:

Step 4: Clean Up

Uninstall the chart to delete the namespace and its resources, including Pods, DaemonSets, Deployments, Services, Secrets, ConfigMaps, etc.:

helm uninstall kubearmor -n kubearmor

Technical Considerations

The Kubearmor 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.

Kubearmor built by Minimus:

Runs as root to support required functions in alignment with the public image.
Requires elevated privileges and host-level access (Linux capabilities such as SYS_ADMIN, SYS_PTRACE, and NET_ADMIN, plus host mounts such as /sys/kernel/security, /sys/kernel/debug, and the container runtime socket) to enforce policies via eBPF and Linux Security Modules.
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.
