Simple and small NFS v4 server based on Alpine for Docker
Exposes a NFS V4 service over TCP port 2049.
This container will use the EXPORTED_DIRECTORY environment variable to configure the directory that will be shared over NFS. You can change the settings with the EXPORT_SETTINGS environment variable.
| Variable | Description | Default |
|---|---|---|
| EXPORTED_DIRECTORY | The directory being shared over NFSv4 | /mnt |
| EXPORT_SETTINGS | Comma-separated settings for all exports | rw,fsid=0,async,no_subtree_check,no_auth_nlm,insecure,no_root_squash,crossmnt |
Mounting
Since we use fsid=0 in the default settings, you don't need to specify the folder when mounting. So you can just mount like this: sudo mount -v x.x.x.x:/ /mnt/mynfs4mount
Make accessible to others
If you want to be able to use another machine to connect to this NFS share, add --net=host to the run command. It will use the hosts networking stack to expose port 2049.
Mounting in another container (Docker in Docker)
Make sure to add the SYS_ADMIN capability or run in privileged mode.
