Docker run on nfs mount causes fail to copy and fail to chown

Question

I have a nfs share which I can mount without issues but docker doesn't want a bar of it :/

If I don't include the nfs volumes it installs fine.

I've tried with the permissions on the nfs share set to "chmod 777" and "chown nobody:nobody".

I can connect to it from my mac and write to the nfs share.

 > docker volume create --driver local \
    --opt type=nfs4 \
    --opt o=addr=192.168.1.48,rw \
    --opt device=:/mnt/tank/virtualisation/database \
    database

> docker volume inspect database
[
    {
        "CreatedAt": "2019-05-14T17:14:54+10:00",
        "Driver": "local",

        "Mountpoint": "/var/lib/docker/volumes/database/_data",
        "Name": "database",

            "device": ":/mnt/tank/virtualisation/database",
            "o": "addr=192.168.1.48,rw",
            "type": "nfs4"
        },
        "Scope": "local"
    }
]

> docker run --name mysql -v database:/var/lib/mysql -v database:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=root -d percona:ps-8


docker: Error response from daemon: failed to copy file info for /var/lib/docker/volumes/database/_data: failed to chown /var/li

Answer 1

I faced the same problem with a NFS share i need to mount as volume in an nginx container.

In my case adding no_root_squash as option for the NFS share solved the problem: this option causes root user/group of NFS client to be mapped to root user/group of the NFS server, as you can read eg here .

So, finally my /etc/exports looks like this:

/tank/honey-files 172.29.6.0/16(rw,sync,no_subtree_check,no_root_squash)

and I can mount it into a container creating a volume

docker volume create honey-files --driver local --opt type=nfs --opt o=addr=172.29.6.200 --opt device=:/tank/honey-files

and using it with docker run / docker service create :

docker run --name nginx --rm -v honey-files:/usr/share/nginx/html -p 30001:80 nginx:latest
docker service create --name nginx -p 30002:80 --mount 'src=honey-files,target=/usr/share/nginx/html' nginx:latest

The question is very old, but... I hope this answer can help you!
