Run Docker in daemon mode

问题

I issued this command

sudo docker daemon -H unix:///var/run/docker.sock -H tcp://xxxx:8400 -H tcp://yyyyy:2375 &

It working fine. but it not returning to my console client. it not finishing the command.

INFO[0000] API listen on 172.31.16.21:8400

this time I can access it from out side client. but if kill that console. I cannot access it from out side client.

any solution for this?

don't know why docker becoming so complex for the beginners :)

Before I say anything else, I need to warn you against running the Docker daemon like this, listening for TCP connections instead of Unix file socket connections. You probably won't listen to me, but when you get some time, you should read the warnings in the documentation I am about to link, because it's dangerous. So, anyways... You are running a docker daemon when you should be changing your initialization options for docker. The documentation details for you which file you should edit in order to change the configuration for the Docker daemon. Be advised that duplicate options in your run command and in the config file will mean that the daemon will not start. So if you change your daemon.json file and also try to run the daemon with those command line options, your server will ignore them both. The file to edit is /etc/docker/daemon.json, and you should set those options in there like this:

{
  hosts: [
    'unix:///var/run/docker.sock',
    'tcp://xxxx:8400',
    'tcp://yyyyy:2375'
  ]
}

Once you have edited that file, you now should restart your docker daemon:

sudo service docker restart

Or if you're using systemd:

sudo systemctl restart docker.service

Also the central problem you are experiencing has to do with running a daemon process inside of a terminal. In the future, look at the nohup command for running a process inside your terminal and keeping it alive after you close the terminal. You can read more at man nohup.
