Hello,
I am trying to use containers in order to build a personal cloud. I am using a NFS server and my VM host is a NFS client, i am trying to use this NFS share in my containers.
Concrete use case :
Seafile Deployment using this example : https://download.seafile.com/d/320e8adf90fa43ad8fee/files/?p=/docker/docker-compose.yml
After many times reading docs, it seems that i have to use docker volume, so i build few volumes like this :
docker volume create --driver local --opt type=nfs --opt o=addr=192.168.2.13,rw --opt device=:/volume1/Cloud/Seafile/MYSQL seafile_mysql
root@Seafile:~# docker volume inspect seafile_data
[
{
"CreatedAt": "2019-10-11T21:30:59+02:00",
"Driver": "local",
"Labels": {},
"Mountpoint": "/var/lib/docker/volumes/seafile_data/_data",
"Name": "seafile_data",
"Options": {
"device": ":/volume1/Cloud/Seafile/DATA",
"o": "addr=192.168.2.13,rw",
"type": "nfs"
},
"Scope": "local"
}
]
I use it in the yml file, i run the containers, i was happy, i put few files in the containers that is using my NFS share and i see that the empty space on host VM was reducing ! which is not expected as it should be stored on the remote NFS server.
root@Seafile:~# df -h
