Container technology (3) mirror summary [16]

（ 13、 ... and ） Mirror summary

In this section, we first discuss the hierarchical structure of mirrors , Then I learned how to build a mirror image , Finally, practice using Docker Hub And local registry.

Mirror common command ：

images     Show a list of mirrors 
history    Show mirror build history 
commit     Create a new image from the container 
build      from  Dockerfile  Build a mirror image 
tag        Call the image  tag
pull       from  registry  Download mirroring 
push       take   Mirror image   Upload to  registry
rmi        Delete  Docker host  In the mirror 
search     Search for  Docker Hub  In the mirror 

（1）rmi

​ rmi Delete only host Image on , Does not delete registry Mirror image . If one mirror corresponds to more than one tag, Only when the last one tag Is deleted , The mirror image is actually deleted . for example host in httpd There are two mirrors tag：

root@cuiyongchao:/dockerfile# docker images httpd
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
httpd               latest              3dd970e6b110        2 weeks ago         138MB
httpd               v1                  3dd970e6b110        2 weeks ago         138MB
root@cuiyongchao:/dockerfile# 

​ Delete debian:latest Just deleted latest tag, The image itself is not deleted .

root@cuiyongchao:/dockerfile# docker rmi httpd:latest 
Untagged: httpd:latest
root@cuiyongchao:/dockerfile# docker images httpd
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
httpd               v1                  3dd970e6b110        2 weeks ago         138MB
root@cuiyongchao:/dockerfile# 

​ Only when httpd: v1 Also when deleted , The entire image will be deleted .

root@cuiyongchao:/dockerfile# docker rmi httpd:v1 
Untagged: httpd:v1
Untagged: httpd@sha256:b82fb56847fcbcca9f8f162a3232acb4a302af96b1b2af1c4c3ac45ef0c9b968
root@cuiyongchao:/dockerfile# docker images httpd
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
root@cuiyongchao:/dockerfile# 

（2）search

​ search Let's not have to open the browser , On the command line, you can search for Docker Hub In the mirror .
