无法在Alpine Linux LXC上启动NFS服务器

我正在尝试按照here所述的说明在Proxmox上运行的Alpine Linux LXC上设置NFS服务器,但是rpc.statd拒绝启动.这是来自/ var / log / messages的摘录,显示错误:

Nov 26 03:08:25 nfs daemon.notice rpc.statd[226]: Version 2.1.1 starting
Nov 26 03:08:25 nfs daemon.warn rpc.statd[226]: Flags: TI-RPC 
Nov 26 03:08:25 nfs daemon.err rpc.statd[226]: Unable to prune capability 0 from bounding set: Operation not permitted
Nov 26 03:08:25 nfs daemon.err /etc/init.d/rpc.statd[224]: start-stop-daemon: failed to start `/sbin/rpc.statd'
Nov 26 03:08:25 nfs daemon.err /etc/init.d/rpc.statd[210]: ERROR: rpc.statd failed to start
Nov 26 03:08:25 nfs daemon.err /etc/init.d/nfs[228]: ERROR: cannot start nfs as rpc.statd would not start

我已经为LXC(找到here)创建了一个自定义apparmor配置文件,以便为服务提供足够的权限来运行,但这没有帮助.

最佳答案
事实证明我需要CAP_SETPCAP功能来运行NFS服务器.

这可以通过编辑/etc/pve/lxc/CTID.conf中的容器配置文件(其中CTID是您的容器ID)来完成,如下所示:

....
# clear cap.drop
lxc.cap.drop:

# copy drop list from /usr/share/lxc/config/common.conf
lxc.cap.drop = mac_admin mac_override sys_time sys_module sys_rawio

# copy drop list from /usr/share/lxc/config/alpine.common.conf with setpcap commented

lxc.cap.drop = audit_write
lxc.cap.drop = ipc_owner
lxc.cap.drop = mknod
# lxc.cap.drop = setpcap
lxc.cap.drop = sys_nice
lxc.cap.drop = sys_pacct
lxc.cap.drop = sys_ptrace
lxc.cap.drop = sys_rawio
lxc.cap.drop = sys_resource
lxc.cap.drop = sys_tty_config
lxc.cap.drop = syslog
lxc.cap.drop = wake_alarm

瞧!
