+docker run --rm check_interfaces -c public -h sw1
+```
+
+Persistent container
+
+```sh
+docker build -t check_interfaces .
+docker create --name="check_sw1" check_interfaces -c public -h sw1
+docker start -a check_sw1
+```
+
+Create a debug build
+
+```sh
+docker build --build-arg target=debug -t check_interfaces .
