我第一次在 stack-overflow 上问问题，在中国，我很少能见到任何厨师开发人员来谈论我的问题，所以我把它贴在这里寻求帮助。这个问题困扰了我好几个星期，我仍在努力解决它。

这是我的错误信息：

我在这里尝试做的是由厨师 docker cookbook 版本 2.14.3 运行一组 docker，名称循环到“localfolder”，当 localfolder =“bootproxy”时，执行 bash 命令以检查 docker 当前正在运行并通过名为“bootproxy”的 nginx docker 链接它们。

我的问题是，每当我清除所有缓存或重新上传所有食谱“网络服务器”后，厨师客户端运行良好而没有错误。但是当我重新运行厨师客户时，我得到了

Docker::Error::ServerError
--------------------------
Could not get container for bootproxy

由于“docker_container”资源中“links”的值变成了“#”，而不是包含当前运行的 docker 名称的数组，例如 [“container1:container1”、“container2:container2”、“container3:container3”]。所以我怀疑尝试从主机获取值的 ruby​​_block 正在被缓存并且在第一次连续执行后没有运行。我的缓存删除（rm -rf /var/chef/cache）证明了这一点，但我无法定义食谱中缓存的删除（也不是解决它的好方法）。我需要让主厨客户端能够重新运行，因为我正在使用它在整个环境中部署我的代码集。请给我任何建议。

谢谢！

我认为您错过了修复第二个资源，它没有使用lazy{}帮助程序。

总的来说，这段代码有点乱，所以一开始很难说出它在做什么。我建议写很多测试，也许更多的评论。
