\*\* **TL;DR I have a working solution below:[NFS Native Support - #4 by seanhandley](https://forums.docker.com/t/nfs-native-support/48531/4)** \*\* Hi there, Has anyone successfully used the new NFS support in the latest D4M 8.03.0-ce-mac59 (23608)? Is there specific documentation for how to get this working? I’ve been trying to get my container to sync with a directory on my mac. The OSX local filesystem is too slow for my Rails app. I’ve tried a few things with docker-compose but I’m unsure what the IP address of the NFS server should be. ``` version: '2' services: api: volumes: - app-sync:/app:nocopy volumes: app-sync: driver_opts: type: "nfs" o: "addr=172.18.0.4,rw" device: ":/app" ``` I’ve had various errors regarding permissions, timeouts, and simply “invalid argument”. Any advice would be greatly appreciated. Some kind of walkthrough would be amazing. Cheers, Sean ---

Hi Sean, I’m using NFS on mac and latest docker. I’m not certain if you want to do the nfs mount in docker or from mac and then bind-mount. I’m using the latter where I mount\_nfs via mac terminal and then use -v option when running docker image. The only issue I found was that I couldn’t write to the nfs volume unless I chmod 777 the files (see an earlier post). btw, where’s info on “new NFS support”? tia. cheers, roy ---

Thanks Roy. I’ve set an NFS share in /etc/exports but I’m not sure which IP/domain I should be using in the `o` string. I’m struggling to find much info on native NFS support, sadly. ---

I have a working solution. Run this: ``` LINE="/Users -alldirs -mapall=$(id -u):$(id -g) localhost" FILE=/etc/exports grep -qF -- "$LINE" "$FILE" || sudo echo "$LINE" | sudo tee -a $FILE LINE="nfs.server.mount.require_resv_port = 0" FILE=/etc/nfs.conf grep -qF -- "$LINE" "$FILE" || sudo echo "$LINE" | sudo tee -a $FILE > /dev/null sudo nfsd restart ``` Now run `docker-compose up` using this: ``` version: '2' services: api: volumes: - "nfsmount:/app" volumes: nfsmount: driver: local driver_opts: type: nfs o: addr=addr=host.docker.internal,rw,nolock,hard,nointr,nfsvers=3 device: ":${PWD}" ``` This will mount the current directory (PWD) into `/app` inside the container. ---

Hi seanhandley. I’ve try your solution but not working for me. On my exports I have this : /Users -alldirs -mapall=501:20 localhost And same than you on my docker-compose but I have permission denied when I up. I used last version of docker for Mac. ---

Ok, that looks fine. Can you add this to /etc/nfs.conf ? ``` nfs.server.mount.require_resv_port = 0 ``` Then run ``` sudo nfsd restart ``` and try docker-compose again? ---

Sorry, I’m not sure what you can do. This solution relies on mapping UID/GID to a known pair on OSX - as such this means you can’t chown files inside the container and expect the operation to succeed on the mounted directory. There is an option called `no_root_squash` for NFS which you can add to `/etc/exports` but it seems the OSX version of NFS doesn’t support this feature. ---

I’m coming back after a few day of work with symfony and docker volume nfs and … It was good for perf on display website. It was not good for development. A lot of time were I work I have to wait when I refresh website because they don’t have access to the file that I modify. It was maybe a issue with the sync but for development, it’s annoying to wait after modify file, it’s a waste of time. Conclusion, it’s a lot better but for web development with symfony it’s not good I must continue to use my VM with Debian and sync file with PhpStorm … ---

You can adjust the NFS options in your docker-compose yaml and see if you get better performance. The settings I landed on were trial and error with a Rails application. Check out the man pages for NFS options and see if tweaking them helps - remember you need to `docker-compose down` and `docker volume prune -f` between changes to the config. ---

Hi Sean, your solution works for me thank you very much! Just one question. Every time I reboot my Mac I need to execute a “sudo nfsd restart” before the “docker-compose up” to get it working properly. Does this happen to you? ---

Hi Manuele, No, this doesn’t happen to me - but the containers I tend to test with aren’t brought up automatically so I suspect nfsd is already running before they start. ---

Even my containers aren’t brought up automatically and I already verified that nfsd is running before bringing them up (with a “ps aux | grep nfsd”). Anyway after a Mac boot, even if nfsd is running, I have to run “sudo nfsd restart” to have those containers working. Thank you for feedback anyway! ---

It may be the same issue we have in Windows where there is a race condition of the share drive not connected yet before the containers start up. The docker managed plugins alleviate the issue by ensuring that they run BEFORE the containers. [Next page](https://forums.docker.com/t/nfs-native-support/48531.md?page=2)
