[筆記] Docker 佈署NFS Server

直接使用container佈署nfs server

NFS Server

NFS server

docker run -itd --privileged \
  --restart unless-stopped \
  -e SHARED_DIRECTORY=/data \
  -v /data/nfs-storage:/data \
  -p 2049:2049 \
  itsthenetwork/nfs-server-alpine:12

or

version: "2.1"
services:
  # https://hub.docker.com/r/itsthenetwork/nfs-server-alpine
  nfs:
    image: itsthenetwork/nfs-server-alpine:12
    container_name: nfs
    restart: unless-stopped
    privileged: true
    environment:
      - SHARED_DIRECTORY=/data
    volumes:
      - ./data/nfs-storage:/data
    ports:
      - 2049:2049
    networks:
      my_nfs_network:
        ipv4_address: 172.16.0.2
networks:
  my_nfs_network:
    driver: bridge
    ipam:
      config:
        - subnet: 172.16.0.0/16

docker compose up -d

NFS Clent

這邊執行為客戶端主機, 簡單說就是要把server的目錄共享在客戶端

sudo mount -v <nfs server ip>:/ <client nfs path>

執行範例
假設客戶端共享目錄為 ./client , 這邊客戶端為為 host主機,
目的是在host主機作與docker內部的nfs server交互
因docekr設置 2049:2049
nfs server ip 直接使用host主機的172.16.1.143,
會直接轉至 nfs server container 內部

sudo mount -v 192.168.1.143:/ ./client
# /home/hccuse/Insync/y40103@gmail.com/GoogleDrive/hccuse/hccuse/learn/nfs/client

這樣就會將 nfs server volume目錄 /data 與 host的 client目錄 共享

hccuse@hcuuse-PC ~/I/y/G/h/h/l/n/client> df
#Filesystem      1K-blocks      Used Available Use% Mounted on
#tmpfs             1576704      2164   1574540   1% /run

取消則在host

sudo umount /home/hccuse/Insync/y40103@gmail.com/GoogleDrive/hccuse/hccuse/learn/nfs/client

Troubleshooting

docker compose 無法卸除 , 可能是client端還在執行, 產生阻塞

Error response from daemon: cannot stop container: a832fb77e839c36d3f961171e5e6af3146ebf9a08ea0f78eff1ff8e31affd4be: tried to kill container, but did not receive an exit event

參考解決方式

sudo systemctl restart docker

killall Docker && open /Applications/Docker.app
