When I run the following cmd in Ubuntu 18.04 ![](/sites/default/files/inline/images/images/image-20190131135158-1.png) the container is created and stays running But when I run this cmd, the container is created but exits immediately ![](/sites/default/files/inline/images/images/image-20190131140124-3.png) ![](/sites/default/files/inline/images/images/image-20190131141732-4.png) Not sure why it is doing this.  if anyone can shed some light, it would be most appreciated.
