This image containerizes the NFS server to share files/directories over the network to devices in the same LAN.
Checkout this link to get started.
Not really useful over the internet because security concerns. It can be tunnelled by SSH but thats quite slow and there are better options.
Based on Alpine Linux from my alpine-s6 image with the s6 init system overlayed in it.
The image is tagged respectively for the following architectures,
- armhf
- armv7l
- aarch64
- x86_64 (retagged as the
latest
)
non-x86_64 builds have embedded binfmt_misc support and contain the qemu-user-static binary that allows for running it also inside an x86_64 environment that has it.
Pull the image for your architecture it's already available from Docker Hub.
# make pull
docker pull woahbase/alpine-nfs:x86_64
-
Only NFSv4 is enabled.
-
Needs
--privileged
. -
Directories are exported from
/etc/exports
. By default it exposes/data
at/
. Remount the exports file with your own configuration, and modify/etc/fstab.nfs
in the client accordingly. -
Default configuration listens to ports
111
and2049
. -
By default runs as
NFSMODE = "SERVER"
, to use it as a client change its value toCLIENT
. However, this way is not really useful unless testing, in reality, the/etc/cont-init.d/20-client
file can be dropped inside any container that usess6
, and combined with/etc/fstab.nfs
it can take care of mounting the directories before applications are started. Default provided at/root/defaults/fstab.nfs
.
If you want to run images for other architectures, you will need to have binfmt support configured for your machine. multiarch, has made it easy for us containing that into a docker container.
# make regbinfmt
docker run --rm --privileged multiarch/qemu-user-static:register --reset
Without the above, you can still run the image that is made for your architecture, e.g for an x86_64 machine..
Running make
starts the service.
# make
docker run --rm -it \
--name docker_nfs --hostname nfs \
--privileged \
-c 256 -m 256m \
-e NFSMODE=SERVER \
-e PGID=1000 -e PUID=1000 \
-p 111:111/tcp -p 111:111/udp \
-p 2049:2049/tcp -p 2049:2049/udp \
-v /data:/data \
-v /etc/hosts:/etc/hosts:ro \
-v /etc/localtime:/etc/localtime:ro \
woahbase/alpine-nfs:x86_64
Running make shell
gets a shell inside the container,
but does not run the init system, so that it can be done manually.
# make shell
docker run --rm -it \
--name docker_nfs --hostname nfs \
--entrypoint /bin/bash \
--privileged \
-c 256 -m 256m \
-e NFSMODE=SERVER \
-e PGID=1000 -e PUID=1000 \
-p 111:111/tcp -p 111:111/udp \
-p 2049:2049/tcp -p 2049:2049/udp \
-v /data:/data \
-v /etc/hosts:/etc/hosts:ro \
-v /etc/localtime:/etc/localtime:ro \
woahbase/alpine-nfs:x86_64
Stop the container with a timeout, (defaults to 2 seconds)
# make stop
docker stop -t 2 docker_nfs
Removes the container, (always better to stop it first and -f
only when needed most)
# make rm
docker rm -f docker_nfs
Restart the container with
# make restart
docker restart docker_nfs
Get a shell inside a already running container,
# make debug
docker exec -it docker_nfs /bin/bash
set user or login as root,
# make rdebug
docker exec -u root -it docker_nfs /bin/bash
To check logs of a running container in real time
# make logs
docker logs -f docker_nfs
If you have the repository access, you can clone and build the image yourself for your own system, and can push after.
Before you clone the repo, you must have Git, GNU make, and Docker setup on the machine.
git clone https://github.com/woahbase/alpine-nfs
cd alpine-nfs
You can always skip installing make but you will have to type the whole docker commands then instead of using the sweet make targets.
You need to have binfmt_misc configured in your system to be able to build images for other architectures.
Otherwise to locally build the image for your system.
[ARCH
defaults to x86_64
, need to be explicit when building
for other architectures.]
# make ARCH=x86_64 build
# sets up binfmt if not x86_64
docker build --rm --compress --force-rm \
--no-cache=true --pull \
-f ./Dockerfile_x86_64 \
--build-arg DOCKERSRC=woahbase/alpine-s6:x86_64 \
--build-arg PGID=1000 \
--build-arg PUID=1000 \
-t woahbase/alpine-nfs:x86_64 \
.
To check if its working..
# make ARCH=x86_64 test
docker run --rm -it \
--name docker_nfs --hostname nfs \
-e PGID=1000 -e PUID=1000 \
woahbase/alpine-nfs:x86_64 \
sh -ec 'rpc.mountd -v; mount.nfs -V'
And finally, if you have push access,
# make ARCH=x86_64 push
docker push woahbase/alpine-nfs:x86_64
