1、发布到DockerHub上

1.地址https://hub.docker.com/注册自己的账号

2.确定这个账号可以登录

3.在服务器上提交自己的镜像

[root@wq test]# docker login --helpUsage:  docker login [OPTIONS] [SERVER]Log in to a registry.If no server is specified, the default is defined by the daemon.Options:-p, --password string   Password--password-stdin    Take the password from stdin-u, --username string   Username#登录成功结果[root@wq test]# docker login -u skymuxuePassword:WARNING! Your password will be stored unencrypted in /root/.docker/config.json.Configure a credential helper to remove this warning. Seehttps://docs.docker.com/engine/reference/commandline/login/#credentials-storeLogin Succeeded

4.登录完毕后就可以提交镜像了，docker push

[root@wq test]# docker imagesREPOSITORY   TAG       IMAGE ID       CREATED        SIZEdiytomcat    latest    dfa3156617fc   40 hours ago   893MB#出现问题如下#直接push出现拒绝[root@wq test]# docker push diytomcatUsing default tag: latestThe push refers to repository [docker.io/library/diytomcat]5f70bf18a086: Preparingba6599e516c6: Preparingff45e9332326: Preparing5cf43dcf601f: Preparingd3b0d4081fd0: Preparing174f56854903: Waitingdenied: requested access to the resource is denied  # 拒绝#出现不存在[root@wq test]# docker push skymuxue/diytomcat:1.0The push refers to repository [docker.io/skymuxue/diytomcat]An image does not exist locally with the tag: skymuxue/diytomcat#解决方法  添加一个tag标签[root@wq test]# docker tag dfa3156617fc skymuxue/tomcat:1.0[root@wq test]# docker imagesREPOSITORY        TAG       IMAGE ID       CREATED        SIZEdiytomcat         latest    dfa3156617fc   40 hours ago   893MBskymuxue/tomcat   1.0       dfa3156617fc   40 hours ago   893MB#docker push上去即可！自己发布的镜像尽量带上版本号[root@wq test]# docker push skymuxue/tomcat:1.0The push refers to repository [docker.io/skymuxue/tomcat]5f70bf18a086: Pushedba6599e516c6: Pushing [============================>                      ]  171.3MB/296.9MBff45e9332326: Pushed5cf43dcf601f: Pushing [===============================>                   ]  240.2MB/376.1MBd3b0d4081fd0: Pushed174f56854903: Pushed

2.找到容器镜像服务

打开容器镜像服务
