Docker run runtime container ends automatically

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 found the Docker container is over

Finding data found that this problem is not complicated because it should be: Docker container background running, you must have a foreground process.

Solution:

1. Release the running process into the foreground such as: Nginx nginx-g "daemon off;" Tomcat/catalina.sh Run

2. Use tail, top this can be the foreground to run the program, especially recommended tail, output your log file.

Add entrypoint/opt/tomcat7.0/bin/startup.sh && tail-f to the Dockerfile/opt/tomcat7.0/logs/catalina.out
