sudo apt update
sudo apt install -y nfs-kernel-server
 
# Create the export directory
sudo mkdir -p /exports/shared
sudo chown nobody:nogroup /exports/shared
sudo chmod 755 /exports/shared
 
# add this to /etc/exports
sudo vi /etc/exports
/exports/shared    192.168.1.0/24(rw,sync,no_subtree_check,no_root_squash)
 
 
# Export the shares
sudo exportfs -ra
 
# Start and enable NFS server
sudo systemctl enable nfs-kernel-server
sudo systemctl start nfs-kernel-server
 
# Verify exports
sudo exportfs -v

Mount NFS Share:

docker volume create \
  --driver local \
  --opt type=nfs \
  --opt o=addr=192.168.1.100,rw,nfsvers=4.1 \
  --opt device=:/exports/shared \
  shared-data

</code bash> mkdir -p web cd web cat >docker-compose.yml «EOF services:
