将修改多的镜像保存成一个新的

[root@#localhost docker]# docker commit 812a997f614a ubuntu:update sha256:317f102584605694da424bc96764559a1ccfda13943353f4cbdfd89c96515e6b

将镜像导出到文件

[root@#localhost docker]# docker export cbe3cb7799ed > update.tar

创建一个新静像从基于导出的文件

[root@#localhost /]# docker import - update < update.tar sha256:fd00d520a43eb5dc6cca8717fe0ca04cfdc53b02cad2fb5b50d877b8e6d6c3bc [root@#localhost /]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE update latest fd00d520a43e 13 seconds ago 165 MB ubuntu update 317f10258460 11 minutes ago 188 MB twang2218/gitlab-ce-zh 9.0.3 36172b5fefab 44 hours ago 1.19 GB gitlab/gitlab-ce latest 5eff2e44957c 2 days ago 1.11 GB mysql latest 9546ca122d3a 8 days ago 407 MB wordpress latest 4ad41adc2794 2 weeks ago 401 MB ubuntu 14.04 7c09e61e9035 5 weeks ago 188 MB daocloud.io/library/nginx 1.7.1 e3e043d3ed2f 2 years ago 499 MB [root@#localhost /]# 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 save 和load （像当与镜像的备份和恢复）

update是一个已经存在的镜像

[root@#localhost /]# docker save -o update1.tar update [root@#localhost /]# ls bin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp update1.tar update.tar usr var [root@#localhost /]# du -sh update1.tar 166M update1.tar

删除update镜像

[root@#localhost /]# docker rmi update Untagged: update:latest Deleted: sha256:fd00d520a43eb5dc6cca8717fe0ca04cfdc53b02cad2fb5b50d877b8e6d6c3bc Deleted: sha256:14cc8cd7b783152682835346e5fe90860a9feeb684866688692285319d4e97ad
