无法在 cAdvisor 中获取容器“/” Docker

Question

我用这个命令运行了 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

我可以运行而不会出错：

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 go 到localhost:8080时，我给我这个错误信息
无法获取容器“/”，错误：无法在 memory 缓存中找到数据
我尝试使用sudo docker 运行仍然是同样的错误。

我怎样才能解决这个问题？ 这个docker是related还是cadvisor？

Answer 1

我遇到这个问题是因为旧的 cadvisor 版本不支持“最近的”cgroups 版本。

我升级以解决此问题。

故障排除提示

使用docker logs检索 cadvisor 日志。 我的显示错误如下：
