无法在 cAdvisor Docker 中获取"/"容器

Question

我用这个命令运行cadvisor docker

docker run 
--volume=/:/rootfs:ro 
--volume=/var/run:/var/run:rw  
--volume=/sys:/sys:ro  
--volume=/var/lib/docker/:/var/lib/docker:ro  
--volume=/dev/disk/:/dev/disk:ro  
--publish=8080:8080  --detach=true 
--name=cadvisor 
gcr.io/google-containers/cadvisor:v0.36.0

我可以运行而不出现错误:

CONTAINER ID   IMAGE                                       COMMAND                  CREATED          STATUS                    PORTS                                       NAMES
a0aa3cc8d5f2   gcr.io/google-containers/cadvisor:v0.36.0   "/usr/bin/cadvisor -…"   48 seconds ago   Up 48 seconds (healthy)   0.0.0.0:8080->8080/tcp, :::8080->8080/tcp   cadvisor

当我进入localhost:8080，我给我这个错误消息
未能获得容器"/"错误:无法在内存缓存中找到数据
我试着用sudo docker run还是同样的错误。

我该如何解决这个问题?这是docker相关的还是cadvisor?

我遇到这个问题是因为旧的cadvisor版本不支持"recent"并且版本。

我升级了这个问题。

故障排除技巧使用docker logs检索cadvisor日志。我的错误显示如下:
