The use of docker

1. Search for available docker images

Docker search httpd

Docker search tutorial

You can also use the website to search

2. Download the container image

On docker's image index website, images are stored according to the user name / image name.

Docker pull learn/tutorial

3. Hello world, run the container

Docker run learn/tutorial echo "hello word"

4. Add functions to the container: install ping programs in the learn/tutorial image

Docker run learn/tutorial apt-get install-y ping

5. Save the modification and testing of the container

Use the docker ps-l command to get the id of the container after installing the ping command

The save command is docker commit id newname, run docker commit 67f88 learn/ping

Usually, you do not need to copy the complete id. After executing the docker commit command, you will return the id number of the new version of the image, such as f0645a51a88f9c5063e96b5a7b160bdadfaf13ed22fe26124ee8497e3af47e84 in the figure.

Run the new mirror docker run lean/ping ping www.baidu.com

6. Check the running image

Use the docker ps command to view a list of all running containers

Docker inspect ca5cf5 view container details

7. Publish an image to https://hub.docker.com/

You need to have your own hub.docker account first.

Play tag:docker tag learn/ping binggongzi/publiclearn for the image

Then push goes up: docker push binggongzi/publiclearn

Note: the docker commit 67f88 learn/ping:14.4 colon is followed by a label
