1.创建镜像build
[root@worker1 ~]# docker image build -t harbor.rzl.com/test/nginx:v1 . Sending build context to Docker daemon 130.8MB Step 1/6 : FROM nginx ---> 2622e6cca7eb Step 2/6 : ENV LANGUAGE en_US.utf8 ---> Running in 14c9f9fec2bb Removing intermediate container 14c9f9fec2bb ---> 6fc071080f58 Step 3/6 : ENV LANG en_US.utf8 ---> Running in e7a55ee7fb8d Removing intermediate container e7a55ee7fb8d ---> dcb843f50dba ..............................
2.下载镜像
[root@worker1 ~]# docker pull nginx:1.14 1.14: Pulling from library/nginx 27833a3ba0a5: Downloading [======================================> ] 17.36MB/22.5MB 0f23e58bd0b7: Downloading [=========================================> ] 18.48MB/22.2MB 8ca774778e85: Download complete
3.查看镜像
[root@worker1 ~]# docker image ls
4.查看镜像分层
[root@worker1 ~]# docker image history 2622e6cca7eb IMAGE CREATED CREATED BY SIZE COMMENT 2622e6cca7eb 3 weeks ago /bin/sh -c #(nop) CMD ["nginx" "-g" "daemon… 0B <missing> 3 weeks ago /bin/sh -c #(nop) STOPSIGNAL SIGTERM 0B <missing> 3 weeks ago /bin/sh -c #(nop) EXPOSE 80 0B
...................
[root@worker1 ~]# docker image inspect 2622e6cca7eb [ { "Id": "sha256:2622e6cca7ebbb6e310743abce3fc47335393e79171b9d76ba9d4f446ce7b163", "RepoTags": [], "RepoDigests": [ "nginx@sha256:21f32f6c08406306d822a0e6e8b7dc81f53f336570e852e25fbe1e3e3d0d0133" ], "Parent": "", "Comment": "", "Created": "2020-06-09T16:57:42.632836191Z", "Container": "53e54c20f21e263548ac09475373e20dfef58dd38aebc6caec258b4ff6c2446c", "ContainerConfig": { "Hostname": "53e54c20f21e", "Domainname": "", "User": "", "AttachStdin": false, "AttachStdout": false, "AttachStderr": false, "ExposedPorts": { "80/tcp": {}
5.打tag（一般用于上传至自己的私服）
[root@worker1 ~]# docker image tag portainer/portainer:latest harbor.rzl.com/library/portainer:latest
6.删除镜像
[root@worker1 ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE nginx <none> 2622e6cca7eb 3 weeks ago 132MB nginx latest 9beeba249f3e 7 weeks ago 127MB nginx <none> 602e111c06b6 2 months ago 127MB portainer/portainer latest 2869fc110bf7 3 months ago 78.6MB harbor.rzl.com/library/portainer latest 2869fc110bf7 3 months ago 78.6MB [root@worker1 ~]# docker image rm 602e111c06b6 Untagged: nginx@sha256:86ae264c3f4acb99b2dee4d0098c40cb8c46dcf9e1148f05d3a51c4df6758c12 Deleted: sha256:602e111c06b6934013578ad80554a074049c59441d9bcd963cb4a7feccede7a5 Deleted: sha256:81eaddad75aaa517b4a597912da28c2f5b905f6e9789dce3aea874b040aad201 Deleted: sha256:73cafa8418003ecfaa02360f181c132b2cf4b61433e1bd5c84012941105865c8 Deleted: sha256:c2adabaecedbda0af72b153c6499a0555f3a769d52370469d8f6bd6328af9b13
7.推送镜像
[root@worker1 ~]# docker image push harbor.rzl.com/library/portainer:latest The push refers to repository [harbor.rzl.com/library/portainer] 0c26382398c3: Pushing [========================> ] 38.96MB/78.37MB dd4969f97241: Pushed
8.清理镜像（会将没有关联的镜像清理掉）还可以加加参数-a
[root@worker1 ~]# docker image prune WARNING! This will remove all dangling images. Are you sure you want to continue? [y/N] y Total reclaimed space: 0B
9.保存镜像
[root@worker1 ~]# docker image save -o nginx.tar nginx:latest [root@worker1 ~]# ls anaconda-ks.cfg basic.sh log.log nginx.tar portainer
10.导入镜像
[root@worker1 ~]# docker image load < nginx.tar ffc9b21953f4: Loading layer [==================================================>] 72.49MB/72.49MB 2f4accd375d9: Loading layer [==================================================>] 58.12MB/58.12MB 6c7de695ede3: Loading layer [==================================================>] 3.584kB/3.584kB Loaded image: nginx:latest
