Docker 之 镜像管理

一、镜像查询

二、镜像拉取

[root@docker network-scripts]# docker pull alpineUsing default tag: latest      #默认最新版本，可指定版本如：docker pull alpine:3.10.3latest: Pulling from library/alpine e6b0cf9c0882: Pull complete Digest: sha256:2171658620155679240babee0a7714f6509fae66898db422ad803b951257db78Status: Downloaded newer image for alpine:latestdocker.io/library/alpine:latest         #镜像的构备注：docker pull alpine 可改成 docker.io/library/apline:latest

三、查看本地镜像

[root@docker network-scripts]# docker images      #查看本地镜像REPOSITORY          TAG                 IMAGE ID            CREATED             SIZEalpine              latest              cc0abc535e36        12 days ago         5.59MBhello-world         latest              fce289e99eb9        12 months ago       1.84kB

四、给镜像打标签

[root@docker network-scripts]# docker tag cc0abc535e36 docker.io/zhoumingkang/alpine:v3.10.3# cc0abc535e36：镜像IMAGE ID#docker.io/zhoumingkang/alpine:v3.10.3：镜像的结构[root@docker network-scripts]# docker imagesREPOSITORY            TAG                 IMAGE ID            CREATED             SIZEalpine                latest              cc0abc535e36        12 days ago         5.59MBzhoumingkang/alpine   v3.10.3             cc0abc535e36        12 days ago         5.59MBhello-world           latest              fce289e99eb9        12 months ago       1.84kB

五、把zhoumingkang/alpine:v3.10.3推送到自己的仓库上

[root@docker network-scripts]# docker push docker.io/zhoumingkang/alpine:v3.10.3The push refers to repository [docker.io/zhoumingkang/alpine]6b27de954cca: Mounted from library/alpine v3.10.3: digest: sha256:3983cc12fb9dc20a009340149e382a18de6a8261b0ac0e8f5fcdf11f8dd5937e size: 528

六、移除一个标签

[root@docker network-scripts]# docker imagesREPOSITORY            TAG                 IMAGE ID            CREATED             SIZEzhoumingkang/alpine   v3.10.3             cc0abc535e36        12 days ago         5.59MBalpine                latest              cc0abc535e36        12 days ago         5.59MBalpine                3.9.4               055936d39205        8 months ago        5.53MBhello-world           latest              fce289e99eb9        12 months ago       1.84kB[root@docker network-scripts]# docker rmi docker.io/library/alpine:latestUntagged: alpine:latest    #移除标签Untagged: alpine@sha256:2171658620155679240babee0a7714f6509fae66898db422ad803b951257db78[root@docker network-scripts]# docker imagesREPOSITORY            TAG                 IMAGE ID            CREATED             SIZEzhoumingkang/alpine   v3.10.3             cc0abc535e36        12 days ago         5.59MBalpine                3.9.4               055936d39205        8 months ago        5.53MBhello-world           latest              fce289e99eb9        12 months ago       1.84kB

七、删除一个镜像

[root@docker network-scripts]# docker imagesREPOSITORY            TAG                 IMAGE ID            CREATED             SIZEzhoumingkang/alpine   v3.10.3             cc0abc535e36        12 days ago         5.59MBalpine                3.9.4               055936d39205        8 months ago        5.53MBhello-world           latest              fce289e99eb9        12 months ago       1.84kB[root@docker network-scripts]# docker rmi -f cc0abc535e36Untagged: zhoumingkang/alpine:v3.10.3Untagged: zhoumingkang/alpine@sha256:3983cc12fb9dc20a009340149e382a18de6a8261b0ac0e8f5fcdf11f8dd5937eDeleted: sha256:cc0abc535e36a7ede71978ba2bbd8159b8a5420b91f2fbc520cdf5f673640a34Deleted: sha256:6b27de954cca6332272e7709b7d8ceccee1489d9452af73391df360a26123580[root@docker network-scripts]# docker imagesREPOSITORY          TAG                 IMAGE ID            CREATED             SIZEalpine              3.9.4               055936d39205        8 months ago        5.53MBhello-world         latest              fce289e99eb9        12 months ago       1.84kB

八、把刚刚删除的镜像，从远程仓库再拉取回来

[root@docker network-scripts]# docker pull docker.io/zhoumingkang/alpine:v3.10.3v3.10.3: Pulling from zhoumingkang/alpinee6b0cf9c0882: Pull complete Digest: sha256:3983cc12fb9dc20a009340149e382a18de6a8261b0ac0e8f5fcdf11f8dd5937eStatus: Downloaded newer image for zhoumingkang/alpine:v3.10.3docker.io/zhoumingkang/alpine:v3.10.3[root@docker network-scripts]# docker imagesREPOSITORY            TAG                 IMAGE ID            CREATED             SIZEzhoumingkang/alpine   v3.10.3             cc0abc535e36        12 days ago         5.59MBalpine                3.9.4               055936d39205        8 months ago        5.53MBhello-world           latest              fce289e99eb9        12 months ago       1.84kB

九、Docker 镜像特性
