Commands to execute background process in Docker C

2019-03-10 18:53发布

I am creating a docker image using a Dockerfile. I would like to execute some scripts while starting the docker container. Currently I have a shell script to execute all the necessary processes

CMD ["sh","start.sh"]

I would like to execute a shell command with a process running in background example

CMD ["sh", "-c", "mongod --dbpath /test &"]

#!/bin/sh
...
nohup sh -c mongod --dbpath /test &
