技术提示＃57说明了如何创建自己的Docker映像。 那个特定的博客专门展示了如何在CentOS和Ubuntu上构建自己的WildFly Docker映像。 现在，您可以与世界其他地方分享您的图像了。 这就是Docker Hub派上用场的地方。
Docker Hub是Docker的“分发组件”，或者是存储和搜索映像的地方。 从《 Docker Hub入门》文档中……
Docker Hub是用于处理Docker及其组件的集中资源。 Docker Hub可帮助您与同事协作并充分利用Docker。
使用Docker Hub启动和推送映像非常简单。
- 将映像推送到Docker Hub需要一个帐户。 可以按照此处的说明进行创建。 或者使用
docker login命令轻松实现。wildfly-centos> docker login Username: arungupta Password: Email: [email protected] Login Succeeded在WildFly上搜索显示有72张图像：
