The first acquaintance of container in docker Learning

image is a class, container is an instantiated class object

The fastest way to create a container based on an image is

docker run skinglzw/hello-world Running a docker is a container

cd /root/hello-world

View containers currently running locally

docker container ls

docker container ls -a Lists all containers, including running ones

more Dockerfile

docker run centos:7

Method for interactively running containers

docker run -it centos

Exit docker

exit

docker image Enter

docker container Enter

delete a container

docker container rm 3b507da48bdc equals docker rm 3b507da48bdc

docker container ls -a equals docker ps -a

Delete image

docker image rm fce289e99eb9 equals docker rmi fce289e99eb9

docker run skinglzw/hello-world executes 5 times to create container

docker ps -a

docker container ls -aq enumerates all containerId similar to docker container ls -a| awk {'print$1'}

docker rm $(docker container ls -aq) Delete all containers

docker

There are 5 identical image containers deleted in batches

docker container ls -f "status=exited" List the status is exited

docker container ls -f "status=exited" -q List containerId only

docker rm $(docker container ls -f "status=exited" -q)
