Try It Out
In this example we will deploy ExternalDNS on a Kubernetes cluster using the Minimus ExternalDNS FIPS Helm chart. ExternalDNS will automatically manage DNS records for your Kubernetes Services and Ingresses.
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 external-dns-fips
Step 3: Deploy the Helm Chart
Deploy the Minimus Helm chart:
helm install my-external-dns-fips oci://helm.mini.dev/external-dns-fips \
--version 1.21.1 \
-n external-dns-fips \
--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-external-dns-fips oci://helm.mini.dev/external-dns-fips \
--version 1.21.1 \
-f values.yaml \
-n external-dns-fips \
--wait
Step 4: Verify ExternalDNS FIPS is Running
Confirm the chart deployed successfully and ExternalDNS started:
kubectl get pods -n external-dns-fips
You should see output similar to:
NAME READY STATUS RESTARTS AGE
my-external-dns-fips-xxxxxxxxx-xxxxx 1/1 Running 0 2m
Step 5: Test HTTP Endpoint
Forward the ExternalDNS metrics port to your local machine:
kubectl port-forward svc/my-external-dns-fips -n external-dns-fips 7979:7979
In a separate terminal, test the health endpoint:
curl -sf http://localhost:7979/healthz
You should see a successful response confirming ExternalDNS is healthy.
Step 6: Clean Up
Uninstall the chart and delete the namespace to remove all resources:
helm uninstall my-external-dns-fips -n external-dns-fips
kubectl delete namespace external-dns-fips
