Can docker copy the image environment?

How docker copies the image environment:

(1) Export the image on the existing mirror system

docker save microservice_img > /z/microservice_img.tar

The image is saved as an image file (mirror Already exists):

docker save -o update1.tar update (update is an existing image)

(2) Copy the docker image to the corresponding system, such as centos;

(3) Start docker on the corresponding computer

#Restart docker

sudo systemctl restart docker

(4) Import the image (two ways)

#Import the image file

docker load --input /z/microservice_img.tar

#Import through symbols

docker load < /z/microservice_img.tar

(5) Check whether the image is imported successfully

Execute the command: docker images

docker images -a

(6) Run the image in the container

# Run the microservice_img image in the new test container

docker run -it -p 8899:8899 --name test microservice_img
