## 容器镜像

Docker 一直是创建和管理**容器镜像**和**容器**的主要工具之一。

还有一个公共 <a href="https://hub.docker.com/" class="external-link" target="_blank">Docker Hub</a> ，其中包含预制的 **官方容器镜像**, 适用于许多工具、环境、数据库和应用程序。

例如，有一个官方的 <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Python 镜像</a>。

还有许多其他镜像用于不同的需要（例如数据库），例如：


* <a href="https://hub.docker.com/_/postgres" class="external-link" target="_blank">PostgreSQL</a>
