    When using Kubernetes in an air-gapped environment, you need to configure it to use your private registry.
 
    1. **Create a kubernetes secret for registry authentication**:
 
-     .. code-block:: bash
+      .. code-block:: bash
 
-        kubectl create secret docker-registry regcred \
-          --docker-server=registry.example.com:5000 \

-          --docker-password=your_password \

+         --docker-username=your_username \
+         --docker-password=your_password \
+         [email protected]
 
    2. **Reference the secret in pod specifications**:
 
-     .. code-block:: yaml
+      .. code-block:: yaml
 
-        apiVersion: v1
-        kind: Pod

-        spec:
-          containers:
-          - name: mattermost
-            image: registry.example.com:5000/mattermost/mattermost-enterprise-edition:latest
-          imagePullSecrets:

+           imagePullSecrets:
+           - name: regcred
 
    3. **For Helm deployments**, specify the registry in ``values.yaml``:
 
-     .. code-block:: yaml
+      .. code-block:: yaml
 
-        image:
-          repository: registry.example.com:5000/mattermost/mattermost-enterprise-edition
