+Build the Docker image:
+
+```bash
+docker build -t mtl-manager:latest .
+# docker build -t mtl-manager:latest --build-arg HTTP_PROXY=$http_proxy --build-arg HTTPS_PROXY=$https_proxy .
+```
+
+Run the Docker container as a daemon:
+
+```bash
+docker run -d \

+Print the MTL Manager logs:
+
+```bash
+docker logs -f mtl-manager
+```
+
+Shutdown the Docker container with SIGINT:
+
+```bash
+docker kill -s SIGINT mtl-manager
+# docker rm mtl-manager
