Start the container docker start container Id or container name

docker start container ID or container name

Enter the container docker exec -it container id (recommended names)

Docker exec -it container id (names are recommended) followed by ls to see those directories
Docker exec -it container id bash

docker attach container ID or container name

exit the container exit

exit The container stops exiting
ctrl+P+Q The container does not stop exiting

Restart the container docker restart container ID or container name

Stop container docker stop container ID or container name

Violent deletion, kill the process directly (not recommended)
docker kill container ID or container name

delete container docker rm container id

docker rm container ID

If you delete the running container, an error will be reported. If we need to delete it, we need to force it to delete;

force delete docker rm -f container id

Delete multiple containers
docker rm -f container ID1 container ID2 separated by spaces

Remove all containers
docker rm -f $(docker ps -qa)

If you delete a running container, an error will be reported. If we need to delete it, we need to force deletion;
force deletion docker rm -f container ID
delete multiple containers
docker rm -f container ID1 container ID2 separated by spaces
Delete all containers
docker rm - f $(docker ps -qa)

Mount the container directory docker run -it -v /host directory:/container directory:ro image name

Implementation:
docker run -it -v /host directory:/container directory image name
Multi-directory mount
docker run -it -v /host directory:/container directory-v /host directory2:/container directory2 image name

Note:
If you are synchronizing a multi-level directory, there may be a prompt about insufficient permissions;
this is because the security module selinux in Centos7 has disabled permissions, we need to add --privileged=true to solve the problem that the mounted directory has no permissions The problem;

The mount directory is read-only:
docker run -it -v /host directory:/container directory:ro image name
