I've been using Docker all the way, and I don't remember all the way. If I don't remember it, it's Baidu. It's better to remember one. The big guy has always called others Baidu, how can he Baidu.
----------------View the mirror--------------------
If you, like me, use Docker once a year and don’t like to remember, then there must be this problem:
docker images
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
Solution:
sudo su
service docker start
---------------View junk---------------------
sudo du -hs / var / lib / docker
-------------- Load the image package to the local mirror warehouse ------------------------
If the great pot of heaven is for you, the image package named XXX.tar
sudo docker load --input XXX.tar
and then input sudo docker images to see this thing in the local mirror warehouse.
---------------Run the image (create a container) --------------------
sudo docker run --name cy [container name] -it -p 2200:2200 -v /home/dl/yw/cy [host external folder] :/cy [container internal folder] XXX [image name (don’t tar Suffix)] :2.0 [version number] /bin/bash
Then you enter the container, you exit again , and you exit the container again.
---------------View container------------------
sudo docker ps -a
---------------Run the container------------------
Suppose you have created a container, but exited, and now you want to go in again.
sudo docker start -ia cy [container name]
---------------Delete the container------------------
sudo docker rm cy [container name]
---------------Packing the modified image------------------
sudo docker save -o XXXX [new name] .tar XXX [old name] :2.0 [version number]
---------------Delete the mirror------------------
sudo docker rmi ID [Mirror image IMAGE ID]
all in all:
The local mirror library has a bunch of images, and each image can have a bunch of containers.
The original image can be downloaded from the Docker official website, and then modified and packaged into your own image.
