volumes

You will need to provide the container with the volume(s) that you want to expose via nfs

-v <local path>:<path in container>

environment variables

You will need to provide at the following 3 environment variables to configure the nfs exports:

  • NFS_EXPORT_DIR_1
  • NFS_EXPORT_DOMAIN_1
  • NFS_EXPORT_OPTIONS_1

When the container is started, the environment variables are parsed and the following output is created in /etc/exports file:

NFS_EXPORT_DIR_1 NFS_EXPORT_DOMAIN_1(NFS_EXPORT_OPTIONS_1)

for the example given the following line in /etc/exports would be created:

/nfs *(ro,insecure,no_subtree_check, no_root_squash, fsid=1)

To define multiple exports, just increment the index on the environment variables

build command

docker build -t fuzzle/docker-nfs-server:v1 .

inspect running container

docker exec -ti CONTAINER bash

mounting the nfs share from another host

mount -v -t nfs -o ro,nfsvers=3,nolock,proto=udp,port=2049 <ip_address_docker_host>:/nfs /mnt/scratch
