别着急,坐和放宽
今天想折腾下Grafana
+cadvisor
+Prometheus
的组合来监控下服务器的Docker应用
但部署cadvisor时出现了点问题:
Docker命令:
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=9101:8080 \
--detach=true \
--name=cadvisor \
google/cadvisor:latest
容器启动失败:
F1006 07:45:20.802587 1 cadvisor.go:146] Failed to create a Container Manager: mountpoint for cpu not found
查了一下ds和bing,结论是Ubuntu24使用了cgroup v2
,但cAdvisor
依然尚不支持
那很糟糕了
遂有此文
参考这篇博文 (CSDN难得有好文章)
编辑GRUB文件其实是一个相当危险的行为,请量力而行
编辑如下文件:/etc/default/grub
(要碰我不熟悉的Linux了,好害怕)
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`( . /etc/os-release; echo ${NAME:-Ubuntu} ) 2>/dev/null || echo Ubuntu`

# If your computer has multiple operating systems installed, then you

# Uncomment to get a beep at grub start

瑟瑟发抖地在终端中敲下了:
sudo update-grub #必须要有这一步
sudo reboot
万幸启动成功了
可以看见cAdvisor启动成功
