+# K8s Docker Registry Configuration
+
+**How to make JSON Configuration**
+
+```json=
+{
+  "auths": {
+    "<your-registry>": {
+      "username": "<your-username>",
+      "password": "<your-password>",
+      "email": "<your-email@example.com>",
+      "auth": "<base64-of-your-username:your-password>"
+    }
+  }
+}
+```
+
+**Replace Values**
+
+- **Replace** <your-registry>: Use the hostname of your Gitea instance (e.g., registry.example.com).
+- **Replace** <your-username>: Use your Gitea username (e.g., user1).
+- **Replace** <your-password>: Use your Gitea personal access token generated with read:package scope (e.g., abc123).
+- **Replace** <your-email>: Use your email address (e.g., user1@example.com).
+
+**Linux Command**
+
+```bash
+echo -n 'your-username:your-password' | base64 -w 0
+```
+
+witch gives `eW91ci11c2VybmFtZTp5b3VyLXBhc3N3b3Jk` then we use it in the `auth`
+
+```bash
+echo -n '{"auths":{"<your-registry>":{"username":"your-username","password":"your-password","email":"your-email","auth":"eW91ci11c2VybmFtZTp5b3VyLXBhc3N3b3Jk"}}}' | base64 -w 0
