A small docker NFS client (multi-arch). Perfect for enabling whatever to NFS, compatible with databases (Angatar> d3fk/nfs-client).
This is a Docker multi-arch image for a light NFS client () compatible with database usage.
We provide 2 tags for this image
- latest: which is the historical tag that is set for NFS 3 by default but the ENVs enable you to change easily to NFS 4 or any other filesystem types supported.
- v4: which is set by default to NFS 4 as a ready to go nfs4 client.
pre-build as multi-arch from Docker hub with "automated build" option.
image name d3fk/nfs-client
docker pull d3fk/nfs-client
Docker hub repository: https://hub.docker.com/r/d3fk/nfs-client/
- d3fk/nfs-client:latest which is the default image when using d3fk/nfs-client but is set with nfs3 (nfs4 and other supported fstypes available by setting ENVs)
- d3fk/nfs-client:v4 which is ready to go as nfs4 client (ENVs still permit to change the default fstype).
Based on https://github.com/flaccid/docker-nfs-client
The image is now built from the original Alpine with automated build. Default NFS type modified to NFS3 for local IT requirements. The entry script was adapted to be compatible with using this NFS client with database (mariadb, mysql...) and to permit running the container without setting the SERVER and SHARE env parameters, simply to share on the host's network the NFS client capabilities for mounting any NFS shared path on the host (quite useful with small os)
The container is now made available as multi-arch image, build from Docker Hub nodes dedicated to automated builds. This multi-arch image will fit most of architectures:
- linux/amd64
- linux/386
- linux/arm/v6
- linux/arm/v7
- linux/arm64/v8
- linux/ppc64le
- linux/s390x
As this container is quite widely used , we'll remain with NFS3 as default FSTYPE on the historical tag "latest" to avoid to create any anoying breaking issue, but the ENVIRONMENT variables enable you to change easily to NFS 4 or any other filesystem types supported: The filesystem types which are currently supported include adfs, affs, autofs, cifs, coda, coherent, cramfs, debugfs, devpts, efs, ext, ext2, ext3, ext4, hfs, hfsplus, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs, nfs4, ntfs, proc, qnx4, ramfs, reiserfs, romfs, squashfs, smbfs, sysv, tmpfs, ubifs, udf, ufs, umsdos, usbfs, vfat, xenix, xfs, xiafs.
A new image tag was created "v4" for the users who needed a ready to go nfs4 client without setting additional ENVIRONMENT variables.
SERVER
- the hostname or IP of the NFS server to connect toSHARE
- the NFS shared path to mountMOUNT_OPTIONS
- mount options to mount the NFS share with; the default isnfsvers=3
on d3fk/nfs-client:latest andnfsvers=4
on d3fk/nfs-client:v4FSTYPE
- the filesystem type; default isnfs
in d3fk/nfs-client:latest for NFS3 mount, and default isnfs4
in d3fk/nfs-client:v4MOUNTPOINT
- the mount point for the NFS share within the container (default is /mnt/nfs-1)
Several possibilities:
Run the container
docker run -itd --privileged=true --net=host d3fk/nfs-client
then you can use NFS to mount all your mountpoints on your host
sudo mount -t nfs SERVER_IP:/shared_path /mount_point
Basic command
docker run -itd --privileged=true --net=host -e SERVER=nfs_server_ip -e SHARE=shared_path d3fk/nfs-client
It is more convenient to set a volume
Simply add a volume if you need to share the volume with other containers or mount it directly on your host (take care to add the :shared mention on the volume option)
docker run -itd --privileged=true --name nfs --net=host -v /mnt/shared_nfs:/mnt/nfs-1:shared -e SERVER=nfs_server_ip -e SHARE=shared_path d3fk/nfs-client
Then, using the --volume-from nfs
option when runing another container will also made available the nfs shared content in this new container
Alternatively if you are not using a "named volume" but a "shared volume" you could also directly mount the host's directory that mounts the nfs in the new container
by adding the nfs service to one of your cloud-config.yml, user-config.yml or enabled service.yml...
i.e: see the file rancheros-cloud-config.yml
You could also use the additional mount syntax addapted to NFS (since you now have a nfs-client started at os startup). ie:
#cloud-config
mounts:
- ["SERVER_IP:/shared_path", "/mnt/nfs-1", "nfs", ""]
