Docker rabbitmq 映像失败并显示 [error] Too short cookie string

Question

看来我在运行 docker-desktop 的 Windows 机器上的 rabbitmq 和 rabbitmq-management docker 映像确实存在问题。

尝试运行它时，在它关闭之前会出现以下日志：

我已经使用这张图片几个月了，没有任何问题，但突然之间它不再工作了。

我也尝试在我的树莓派上运行它。原来它在那里工作，所以它对我来说更像是一个本地的东西，这有点奇怪，因为 docker 基本上是为了避免这些问题。

我还尝试将RABBITMQ_ERLANG_COOKIE 环境变量设置为长名称，但没有成功。有什么想法吗？

Answer 1

我遇到了完全相同的错误，并听从了欧文布朗的建议。不幸的是，删除 rabbitmq 图像并不能解决我的问题，但删除所有其他冗余图像（尤其是大尺寸的图像）也为我解决了问题。

如果您想知道所有图片的大小，您可以查看这些统计信息

docker system df

编辑：

几个小时后我再次遇到同样的问题，我再次研究并发现this answer 解决了我的问题。

比删除图像更重要的是使用以下方法删除卷：

docker volume rm $(docker volume ls -f dangling=true -q) // 删除所有卷

Answer 2

RabbitMQ 好像没有空间来写cookie了： 21:01:21.726 [error] Failed to write to cookie file '/var/lib/rabbitmq/.erlang.cookie': enospc

也许您在 docker 中有一些空间限制，或者您实际上在主机中没有剩余空间？

Answer 3

使用docker run rabbitmq:management 单独启动rabbitmq。

如果仍然出现“Failed to write to cookie file '/var/lib/rabbitmq/.erlang.cookie': enospc”错误，则问题是因为 RabbitMQ 使用的文件已损坏。

由于容器在错误发生后立即退出，并且容器正在从缓存的 docker 映像启动，因此您将无法进入容器来修复问题。相反，您需要删除缓存的图像。

1. 删除最初问题的原因，这可能是分配给 Docker 的内存不足。您可以通过 Docker 的实用程序删除图像或分配更多内存。
2. 删除rabbitmq docker镜像 docker images | grep rabbit 然后 run docker rmi <image_id(s)> 对应每个图像 ID。
3. 删除所有缓存的图像。 使用$ docker images --filter "dangling=true 列出所有图像将 然后，使用$ docker rmi $(docker images -f "dangling=true" -q) 删除它们

最后，使用docker run rabbitmq:management 再次运行rabbitmq。如果它运行无误，您就可以重新开始工作了。
