更新:以下答案适用于 c9.io，不适用于 AWS Cloud9。 AWS Cloud9 允许您像往常一样在您用于环境的任何支持上运行 docker，无论是 EC2 还是其他 VM 提供商。

在 Cloud9 工作区中安装 Docker 将不起作用，因为 C9 工作区在 Docker 上运行。在 Docker 中运行 Docker 需要特殊权限，因此是 advised against by those who know best出于安全原因。

话虽如此，您可以从 SSH workspace 使用 Docker ，它允许您将 Cloud9 连接到您自己的服务器。由于该工作区未在 Docker 中运行(在 Cloud9 的服务器上)，您可以使用它做任何您想做的事情(包括运行 Docker)。
