cert-manager FIPS Helm Chart
The cert-manager FIPS Helm chart automates deployment and configuration of cert-manager in Kubernetes clusters using FIPS-validated Minimus images. cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates.
Prerequisites
- A subscription to the Minimus images included in the chart
- A running Kubernetes cluster (v1.22 or higher is recommended)
kubectl installed and configured- Helm v3.8 or higher for OCI support (Installation instructions)
- Cluster Admin privileges
Note: cert-manager requires CRDs to be installed. You can have the chart install them by setting cert-manager.crds.enabled=true, or pre-install them from the cert-manager releases.
Try It Out
In this example we will deploy cert-manager on a Kubernetes cluster using the Minimus cert-manager FIPS Helm chart. cert-manager will provide automated TLS certificate management for your Kubernetes workloads using FIPS-validated images.
Step 1: Start Cluster
If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions
Step 2: Create Namespace
Create a namespace:
kubectl create ns cert-manager-fips
Step 3: Deploy the Helm Chart
Deploy the Minimus Helm chart:
helm install my-cert-manager-fips oci://helm.mini.dev/cert-manager-fips \
--version v1.20.2 \
-n cert-manager-fips \
--set cert-manager.crds.enabled=true \
--wait
If you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using -f values.yaml:
helm install my-cert-manager-fips oci://helm.mini.dev/cert-manager-fips \
--version v1.20.2 \
-f values.yaml \
-n cert-manager-fips \
--set cert-manager.crds.enabled=true \
--wait
Step 4: Verify cert-manager FIPS is Running
Confirm the chart deployed successfully and cert-manager started:
kubectl get pods -n cert-manager-fips
You should see output similar to:
NAME READY STATUS RESTARTS AGE
my-cert-manager-fips-xxxxxxxxx-xxxxx 1/1 Running 0 2m
my-cert-manager-fips-cainjector-xxxxxxxxx-xxxxx 1/1 Running 0 2m
my-cert-manager-fips-webhook-xxxxxxxxx-xxxxx 1/1 Running 0 2m
Step 5: Test Certificate Issuance
Create a self-signed issuer and certificate to verify cert-manager is working:
cat <<EOF | kubectl apply -f -
apiVersion: cert-manager.io/v1
kind: Issuer
metadata:
name: test-selfsigned
namespace: cert-manager-fips
spec:
selfSigned: {}
---
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
name: test-cert
namespace: cert-manager-fips
spec:
secretName: test-cert-tls
issuerRef:
name: test-selfsigned
kind: Issuer
commonName: test.example.com
dnsNames:
- test.example.com
EOF
Wait for the certificate to be issued:
kubectl wait --for=condition=Ready certificate/test-cert -n cert-manager-fips --timeout=60s
You should see:
certificate.cert-manager.io/test-cert condition met
Step 6: Clean Up
Uninstall the chart and delete the namespace to remove all resources:
helm uninstall my-cert-manager-fips -n cert-manager-fips
kubectl delete namespace cert-manager-fips
