 Basic usage 
   Command to see if docker is working/info? 
     sudo docker info
 
List commands for docker containers? 
     docker ps
All containers -a, only look at the last -l, only return container ID-q
 
Create and name the interactive container? 
     sudo docker run --name my_container -i -t ubuntu /bin/bash
--Name specifies the name of the container, -i means that the container can be used interactively when STDIN is turned on, and -t means what base image is used
 
Start a stopped container? 
     sudo docker start my_container
sudo docker start aa38f0f4
Can be followed by container name or ID
 
Attach to the running container by name/ID? 
     sudo docker attach my_container
 
Create a guardian container? 
     sudo docker run --name daemon_container -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done"
 
View container logs? 
     sudo docker logs daemon_container
-f can be monitored, -tail 10 can see the last 10 lines
 
View the process in the container? 
     sudo docker top daemon_container
 
View the hardware statistics of the container? 
     sudo docker stats daemon_container
 
Start additional processes inside the container? Interactive/Background 
     Backstage:sudo docker exec -d daemon_container touch /etc/config
Interaction:sudo docker exec -t -i daemon_container /bin/bash
 
Stop a running container by name/ID? 
     sudo docker stop daemon_container
 
Program error docker restarts the container automatically? 
     sudo docker run --restart=always --name my_container -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done"
When –restart is always, the container will restart no matter what the exit code of the container is; set to on-failure to automatically restart only when the exit is non-zero. In addition, on-failure can set the number of restarts:--restart=on-failure:5
 
View container details? 
     sudo docker inspect my_container
 
Delete the container? 
     sudo docker rm 80483829fd
 
Create a mirror and bind ports? 
     sudo docker run --name daemon_container -p 8080:80 -d ubuntu /bin/sh -c "while true; do echo hello world; sleep 1; done"
 
 
Image build command 
   List docker images? 
     sudo docker images
You can add a specific mirror name
 
Pull the docker image? 
     sudo docker pull ubuntu:12.04
 
Find a mirror? 
     sudo docker search puppet
 
Log in to Docker Hub? 
     sudo docker login
 
Use the commit command to create a mirror step? 
     Run a container, such as:sudo docker run -i -t ubuntu /bin/bash
Run a bunch of commands in it
Use the exit command to exit the container
Submit a custom container: sudo docker commit 41a932fe hub_name/apache2
41a...is the container ID, hub_name is the warehouse name, apache2 is the image name, and you can :webserveradd tags later
 
Use Dockerfile to create mirror steps? 
     Create Docker file
Build a new image command:sudo docker build -t="hub_name/static_web:v1" .
 
Push the image to Docker Hub? 
     sudo docker push static_web
 
Delete mirror? 
     sudo docker rmi jamtur01/static_web
 
 
docker compose 
   installation 
     sudo pip install docker-compose
 
Test whether it works 
     docker-compose --version
