Docker : Access to the Container

	If you'd like to access to services like HTTP or SSH which is running in Containers as a daemon, set like follows.
[1]	For exmaple, use a Container which has httpd.

# start the Container and connect to the shell session # map the port of Host and the port of Container with "-p xxx:xxx" [root@dlp ~]#  docker run -it -p 8081:80 my_image/centos_httpd /bin/bash # start httpd and exit the Container [root@821bc61cb2e6 /]#  /usr/sbin/httpd &  [root@821bc61cb2e6 /]#  echo "httpd on Docker Container" > /var/www/html/index.html  [root@821bc61cb2e6 /]#  # exit with Ctrl+p, Ctrl+q [root@dlp ~]#  docker ps  CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS 821bc61cb2e6 my_image/centos_httpd:latest "/bin/bash" 54 seconds ago Up 53 seconds 0.0.0.0:8081->80/tcp

[2]	Access to the URL via HTTP from a client which is in the same LAN with Container and make sure it's possible to access normally.
