linux - Gentoo Linux : Docker container doesn't start: cgroup v2

Question

我的 Gentoo 系统(内核 5.4.97)docker 容器无法启动。

我尝试了以下命令:

docker 运行 kubler/mariadb

错误信息是:

docker:来自守护进程的错误响应:OCI 运行时创建失败:container_linux.go:349: 启动容器进程导致“process_linux.go:449: 容器初始化导致\”process_linux.go:415: 设置 cgroup 配置procHooks 进程在设置 cgroup v2 时导致\\\"错误:[无法加载程序:功能未实现]\\\"\"":未知。 ERRO[0000] 等待容器时出错:上下文已取消

docker 守护进程处于事件状态(systemd)

内核:5.4.97

当我执行 docker check 脚本时，我得到这个输出

某些设置声明为“MISSING”，会导致一些问题:

• CONFIG_NETFILTER_XT_MATCH_IPVS内核配置中不存在此选项
• CONFIG_RT_GROUP_SCHED:当我启用此选项时，系统不再启动。在最后一条消息后挂起(“[确定]终止普利茅斯...”)。没有登录提示，也没有 sddm

Docker Gentoo-Wiki 页面与我的内核版本不匹配。 Wiki 页面说应该启用 CFQ IO Scheduler，但我的内核配置中没有此选项(有 BFQ)

我也尝试使用内核引导选项“systemd.unified_cgroup_hierarchy=0”和“systemd.unified_cgroup_hierarchy=1”。但没有任何帮助。

当您使用所需选项(以及这些选项的依赖项)编译内核时，所需选项将显示为“绿色”
