Today, I encountered a dockerfile to create a mirror, the mirror run after the container automatically end the problem.
Start command:
Docker run-d-P 8080:8080-v/usr/local/tomcat7.0/logs:/usr/local/tomcat7.0/logs--name tomcatweb tomcat:7.0
After running with Docker PS fou

Inside the container the PID is 1,ppid is 0.
Outside of the container PID is 2198, PPID is 2179 that is docker-containerd-shim process.
