dockerRMI -F mirror ID image ID image ID# Delete multiple images
docker rmi -f $(docker images -aq)	  # Delete all mirrors

container creation requires the corresponding container, throughdocker pullOperation pulls the corresponding mirror.

docker run [Optional parameter] image

# Common parameter description:
	--name="Name"  		# Specify the name of the container, the default is the mirror when the name of the container is not specified
	-d 					# Specify the container background to run
	-it					# 8 8 8 8 8, and enter the container to view the content
	-p					# Specify container port -P 8080: 8080 Host port: container port-P host port: container port#*Commonly used*-P container port 
 Container 
 -P# Random specified port
	
# Example:
# /bin /bash IT operating method specified interactive controller
[[email protected] ~]# docker run -it centos /bin/bash
[[email protected] /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[[email protected] /]# Exit # Exit container
exit

Note: -D when starting the container in the background, you need to pay attention. If the docker starts, it is easy to run without the front desk program.

# Background startup container /bin /bash similar service to the front desk -C is the script behind
docker run -d centos /bin/bash -c "while true; do echo docker run test ; sleep 1 ; done"
