Mounting nfs shares inside docker container

by

Starting from docker 17.06, you can mount NFS shares to the container directly when you run it, without the need of extra capabilities

export NFS_VOL_NAME=mynfs
export NFS_LOCAL_MNT=/mnt/mynfs
export NFS_SERVER=my.nfs.server.com
export NFS_SHARE=/my/server/path
export NFS_OPTS=vers=4,soft

docker run --mount \
  "src=$NFS_VOL_NAME,dst=$NFS_LOCAL_MNT,volume-opt=device=:$NFS_SHARE,\"volume-opt=o=addr=$NFS_SERVER,$NFS_OPTS\",type=volume,volume-driver=local,volume-opt=type=nfs" \
  busybox ls $NFS_LOCAL_MNT

Alternatively, you can create the volume before the container:

docker volume create \
  --driver local \
  --opt type=nfs \
  --opt o=addr=$NFS_SERVER,$NFS_OPTS \
  --opt device=:$NFS_SHARE \
  $NFS_VOL_NAME

docker run --rm -v $NFS_VOL_NAME:$NFS_LOCAL_MNT busybox ls $NFS_LOCAL_MNT
