alpine linux配置NFS服务

NFS客户端

  • 安装 nfs-utils :

alpine linux安装nfs-utils软件包
sudo apk add nfs-utils
sudo rc-update add nfsmount
sudo rc-service nfsmount start

  • 挂载NFS:

alpine linux挂载NFS
mkdir -p /data/build
mount -t nfs 172.18.0.1:/data/docs/github.com/cloud-atlas/build /data/build

alpine linux容器的NFS客户端

相同的方法，在 在kind运行简单的容器 ，运行 Alpine Docker镜像 的 alpine-nginx 容器，我发现执行NFS挂载时候报错:

flock: unrecognized option: e
BusyBox v1.35.0 (2022-11-19 10:13:10 UTC) multi-call binary.

Usage: flock [-sxun] FD | { FILE [-c] PROG ARGS  }

[Un]lock file descriptor, or lock FILE, run PROG

        -s      Shared lock
        -x      Exclusive lock (default)
        -u      Unlock FD
        -n      Fail rather than wait

参考 Privileged doesn't work #10000 ，在运行容器时候，需要添加一个 --privileged=true 参数。那么对于 kubernetes 的运行容器，则需要有一个配置

  • 运行docker容器对比验证(没有 --privileged=true 参数 ):

    docker run --name alpine-nginx-nfs -it alpine-nginx:20221129-02 /bin/bash

容器内部使用 df -h 查看目录:
