Docker镜像构建成功后只要有docker环境就可以使用但必须将镜像推送到Docker Hub上去。创建的镜像最好要符合Docker Hub的tag要求因为在Docker Hub注册的用户名是liboware最后利用docker push命令推送镜像到公共仓库。

[rootlocalhost ~]注推送Docker Hub速度很慢耐心等待很有可能失败失败会尝试多次重传之后断开推送但已推送上去的会保留保留时间不知道是多久。 hub docker效果 Docker 使用发布的镜像

执行docker push nacos:v1【提示denied: requested access to the resource is denied】我们可以列出所有镜像docker images建立tag将要发布的镜像改到自己账户名下我的账户名liboware
docker tag nacos:v2 liboware/nacos:v2再次推送docker push liboware/nacos:v2【成功】 分享资源 获取以上资源请访问开源项目 点击跳转
