Stop docker-web in docker

Run docker-web web server in a docker; by default the docker image is fetched from a public repository. ($IMAGE_LOCATION)

Start the web server

-r          - start the web server
-p  <port>  - listening base port (default ${PORT} )
-w          - require credentials for web server 
-t          - tls with self signed certificate
-b <addr>   - bind address (default ${HOST})
Stop the web server 
-s          - stop the web server

Common options:

-c  <image> - override the container image location (default ${IMAGE_LOCATION})
-v          - run verbosely
-d          - enable trace within container
