Preface
This is zero basics Docker The second article in the series , In the last article This article takes you to quickly understand and start Docker I've explained to you what is Docker, How to install and use Docker The content of , And right Docker A simple comparison with virtual machine technology is given . In this article, we will strike while the iron is hot , The tasks to be completed are as follows ：
- master Docker Common commands , Contains but is not limited to mirror commands , Container order , And some other commands that are commonly used
- Learn to use official documents to find the corresponding command instructions
- Learn to use the help command to find the corresponding command description
Affirming
Part of the content comes from online resources , If it infringes upon your rights and interests , Please contact the author to delete
Docker Common commands
Docker The official documents are very detailed , About all the command line instructions / standard , You can refer to https://docs.docker.com/reference/
We use docker images Command as an example , It can be found that there are very detailed instructions in the official documents , For each command Introduction , usage , Expand the use of , Parameter options , Example … They are very complete .
In addition, we can also use the help command in the command line to let us know how to use different commands .
1、 Help order
docker version # Show docker Version information for .
docker info # Show docker System information , Including the number of mirrors and containers
docker command --help # Help order
2、 Mirror command
docker images # View images on all local hosts have access to docker image ls Instead of
docker search # Search mirroring
docker pull # Download mirroring docker image pull
docker rmi # delete mirror docker image rm
docker images View images on all local hosts
[root@localhost ~]# docker images

You can see that when there is a shared image ,docker You don't have to download it repeatedly , Great memory savings .
Waiting for download to complete , Let's check the host computer again docker The image file of .
You can find that the downloaded images are quite large , At this time, we can consider deleting some images .
docker rmi delete mirror
docker rmi -f Mirror image id # Delete the specified image
docker rmi -f Mirror image id Mirror image id Mirror image id # Delete multiple images
docker rmi -f $(docker images -aq) # Operation ： Delete all mirrors , Recursive delete

# Execute the copy command , Copy the files in the container to the local machine
[root@localhost /]# docker cp 9a1f7b30a10a:/test.java /home
# You can view it locally from docker Files copied in the container
[root@localhost /]# ls /home
test.java
The copy here is actually a copy process , In the future we will use -v Volume technology , Can achieve , Automatic synchronization of local files within the container .
Summary
Docker There are actually a lot of orders from , We'd better put together a complete command line , If you need to query in the future , You can quickly get .
