一.登录Docker Hub
1>.访问Docker Hub官网(https://hub.docker.com/)
2>.点击“Create Repository”(自行注册一下docker hub官网的id，大约不到2分钟就能搞定）
3>.填写创建仓库的相关信息后，并点击"Create"
4>.镜像仓库创建成功
二.上传镜像到Docker Hub
1>.在命令中中登录Docker Hub
[root@docker101.yinzhengjie.org.cn ~]# docker login -u yinzhengjie2019 Password: WARNING! Your password will be stored unencrypted in /root/.docker/config.json. Configure a credential helper to remove this warning. See https://docs.docker.com/engine/reference/commandline/login/#credentials-store Login Succeeded [root@docker101.yinzhengjie.org.cn ~]#
如下图所示，登录成功可以看到docker的镜像仓库地址。
2>.对本地镜像打tag编号
[root@docker101.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE centos-haproxy v1.8.20 1858fe05d96f 5 hours ago 606MB tomcat-app01 v0.1 bf45c22f2d5b 24 hours ago 983MB tomcat-base 8.5.50 9ff79f369094 2 days ago 968MB jdk-base 1.8.0_231 0f63a97ddc85 2 days ago 953MB centos-base 7.6.1810 b4931fd9ace2 2 days ago 551MB centos centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB registry.cn-beijing.aliyuncs.com/yinzhengjie2020/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# docker image tag centos:centos7.6.1810 yinzhengjie2019/centos:v0.1_centos7.6.1810 [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE centos-haproxy v1.8.20 1858fe05d96f 5 hours ago 606MB tomcat-app01 v0.1 bf45c22f2d5b 24 hours ago 983MB tomcat-base 8.5.50 9ff79f369094 2 days ago 968MB jdk-base 1.8.0_231 0f63a97ddc85 2 days ago 953MB centos-base 7.6.1810 b4931fd9ace2 2 days ago 551MB centos centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB yinzhengjie2019/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB registry.cn-beijing.aliyuncs.com/yinzhengjie2020/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]#
3>.将镜像推送到Docker Hub的Registry
[root@docker101.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE centos-haproxy v1.8.20 1858fe05d96f 6 hours ago 606MB tomcat-app01 v0.1 bf45c22f2d5b 24 hours ago 983MB tomcat-base 8.5.50 9ff79f369094 2 days ago 968MB jdk-base 1.8.0_231 0f63a97ddc85 2 days ago 953MB centos-base 7.6.1810 b4931fd9ace2 2 days ago 551MB centos centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB yinzhengjie2019/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB registry.cn-beijing.aliyuncs.com/yinzhengjie2020/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# [root@docker101.yinzhengjie.org.cn ~]# docker image push yinzhengjie2019/centos:v0.1_centos7.6.1810 The push refers to repository [docker.io/yinzhengjie2019/centos] 89169d87dbe2: Mounted from library/centos v0.1_centos7.6.1810: digest: sha256:747b2de199b6197a26eb1a24d69740d25483995842b2d2f75824095e9d1d19eb size: 529 [root@docker101.yinzhengjie.org.cn ~]#
三.从Docker Hub下载镜像到本地
[root@docker102.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE registry.cn-beijing.aliyuncs.com/yinzhengjie2020/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB [root@docker102.yinzhengjie.org.cn ~]# [root@docker102.yinzhengjie.org.cn ~]# docker image pull yinzhengjie2019/centos:v0.1_centos7.6.1810 v0.1_centos7.6.1810: Pulling from yinzhengjie2019/centos Digest: sha256:747b2de199b6197a26eb1a24d69740d25483995842b2d2f75824095e9d1d19eb Status: Downloaded newer image for yinzhengjie2019/centos:v0.1_centos7.6.1810 docker.io/yinzhengjie2019/centos:v0.1_centos7.6.1810 [root@docker102.yinzhengjie.org.cn ~]# [root@docker102.yinzhengjie.org.cn ~]# [root@docker102.yinzhengjie.org.cn ~]# docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE yinzhengjie2019/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB registry.cn-beijing.aliyuncs.com/yinzhengjie2020/centos v0.1_centos7.6.1810 f1cb7c7d58b7 10 months ago 202MB [root@docker102.yinzhengjie.org.cn ~]# [root@docker102.yinzhengjie.org.cn ~]#
