+# Qdrant TLS Guide
+
+In this guide you create a Qdrant cluster with enabled TLS encryption.
+
+1. Create Qdrant Cluster
+
+```bash
+cat <<EOF | kubectl apply -f -
+apiVersion: qdrant.operator/v1alpha1
+kind: QdrantCluster
+metadata:
+  name: my-auth-cluster
+spec:
+  replicas: 1
+  image: qdrant/qdrant:v1.7.3
+  tls:
+    enabled: true
+EOF
+```
+
+2. Create a new collection to check if operator can connect to the cluster:
+
+```bash
+cat <<EOF | kubectl apply -f -
+apiVersion: qdrant.operator/v1alpha1
+kind: QdrantCluster
+metadata:
+  name: my-notls-cluster
+spec:
+  replicas: 1
+  image: qdrant/qdrant:v1.7.3
+EOF
+```
+
+3. Start a new pod with a Certificate Authority, mounted as a volume from the Kubernetes secret:
+
+```bash
+cat <<EOF | kubectl apply -f -
+apiVersion: v1
+kind: Pod
+metadata:
+  name: tlsclient
+spec:
+  containers:
+  - image: curlimages/curl
+    name: mycurlpod
+    command: ["/bin/sh"]
+    args: ["-c", "while true; do echo hello; sleep 10;done"]
+    volumeMounts:
+      - name: cert
+        readOnly: true
+        mountPath: "/cert/cacert.pem"
+        subPath: cacert.pem
+  volumes:
+    - name: cert
+      secret:
+        secretName: my-tls-cluster-server-cert
+        items:
+          - key: cacert.pem
+            path: cacert.pem
+EOF
+```
+
+4. Wait for the pod readiness and connect to it:
+
+```bash
+kubectl wait pods tlsclient --for condition=Ready --timeout=300s
+kubectl exec -it tlsclient -- sh
+```
+
+5. Request the collection list to check if HTTPS works:
+
+```bash
+curl --cacert /cert/cacert.pem https://my-tls-cluster.default:6333/collections
+```
+
+You will see a similar output:
+
+```console
+{"result":{"collections":[{"name":"my-tls-collection"}]},"status":"ok","time":0.000017}
+```
+
+6. Press `CTRL-D` to exit the pod shell.
+
