If the program keeps deploy, there must be something wrong.

Mac installation

Brew install mesosbrew upgrade mesos

Start zookeeper start master

Start slave (pay attention to the port, if a port such as 80 is used in marathon, the ports range needs to be large enough)

Start nginx from marathon using docker

Outside of container, Marathon assigns a random port (hostPort setting is 0)
