Ingress-Nginx-Controller Overview

Secure your stack with a hardened Ingress-Nginx-Controller 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.

Use the Ingress-Nginx-Controller container image in Kubernetes clusters to manage ingress resources.

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 official Helm chart repository to your local Helm client:

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx
helm repo update

Step 3: Create a Local YAML File to Override Chart Defaults

Save the code below to a values.yaml file in your project directory to customize the controller's container image registry and set strict security contexts for webhook jobs to improve runtime security:

cat <<EOF > values.yaml
controller:
  image:
    repository: reg.mini.dev/ingress-nginx-controller
    tag: latest
    digest: null
    runAsUser: 1000
    runAsGroup: 1000
  admissionWebhooks:
    createSecretJob:
      securityContext:
        runAsUser: 1000
        runAsGroup: 1000
        runAsNonRoot: true
        readOnlyRootFilesystem: true
        allowPrivilegeEscalation: false
        capabilities:
          drop:
            - ALL
        seccompProfile:
          type: RuntimeDefault
    patch:
      securityContext:
        runAsUser: 1000
        runAsGroup: 1000
        runAsNonRoot: true
EOF

For the purpose of this test, we pass the Minimus token inline. Standard practice is to create a Kubernetes secret. Learn more

Step 4: Deploy the Chart

Deploy the Helm chart using your values.yaml file:

helm upgrade --install ingress-nginx ingress-nginx/ingress-nginx -f values.yaml

Step 5: Monitor Pod Status

Verify the deployment by checking that at least one ingress-nginx-controller Pod is in the Running state:

kubectl get pods -A

You should see something like:

ingress-nginx-controller-xxxx   Running

Technical Considerations

The Ingress-Nginx-Controller 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.

Ingress-Nginx-Controller built by Minimus:

Runs as non-root by default for a security-first approach that protects against privilege escalation attacks. The public image runs as root.
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.
