Try It Out
In this example we will deploy External Secrets Operator on a Kubernetes cluster using the Minimus External Secrets Operator Helm chart. The operator will manage syncing secrets from external secret management systems into Kubernetes.
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-secrets
Step 3: Deploy the Helm Chart
Deploy the Minimus Helm chart:
helm install my-external-secrets oci://helm.mini.dev/external-secrets \
--version 2.7.0 \
-n external-secrets \
--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-secrets oci://helm.mini.dev/external-secrets \
--version 2.7.0 \
-f values.yaml \
-n external-secrets \
--wait
Step 4: Verify External Secrets Operator is Running
Confirm the chart deployed successfully and all pods are running:
kubectl get pods -n external-secrets
You should see output similar to:
NAME READY STATUS RESTARTS AGE
my-external-secrets-xxxxxxxxx-xxxxx 1/1 Running 0 2m
my-external-secrets-cert-controller-xxxxxxxxx-xxxxx 1/1 Running 0 2m
my-external-secrets-webhook-xxxxxxxxx-xxxxx 1/1 Running 0 2m
Step 5: Test Secret Syncing
Create a Fake SecretStore and an ExternalSecret to verify the operator is functioning:
cat <<EOF | kubectl apply -f -
apiVersion: external-secrets.io/v1beta1
kind: SecretStore
metadata:
name: test-store
namespace: external-secrets
spec:
provider:
fake:
data:
- key: /test/secret
value: hello-eso
version: "v1"
---
apiVersion: external-secrets.io/v1beta1
kind: ExternalSecret
metadata:
name: test-secret
namespace: external-secrets
spec:
refreshInterval: "0"
secretStoreRef:
name: test-store
kind: SecretStore
target:
name: test-result
data:
- secretKey: greeting
remoteRef:
key: /test/secret
version: "v1"
EOF
Wait for the ExternalSecret to sync:
kubectl wait --for=condition=Ready externalsecret/test-secret -n external-secrets --timeout=60s
Verify the synced secret value:
kubectl get secret test-result -n external-secrets -o jsonpath='{.data.greeting}' | base64 -d
You should see:
Step 6: Clean Up
Uninstall the chart and delete the namespace to remove all resources:
helm uninstall my-external-secrets -n external-secrets
kubectl delete namespace external-secrets
