Hi ,

I am trying nfs mount voume using compose but getting error.

cmopose file:
version: ‘3.2’
services:
mongodb:
image: mongo:3.6.1
container_name: mongodb
volumes:
- “nfs-docker2:/data/db”
ports:
- 27010:27017
command: mongod
volumes:
nfs-docker2:
driver: local
driver_opts:
type: nfs
o: addr= “111.111.111.111:/data/mongodata”
device: “:/mnt/netcool-mongodata”

/data/mongodata is the path where i would like to store the data in the mount machine.

Error am getting:
Creating volume “mongo_nfs-docker2” with local driver
Creating mongodb … error

ERROR: for mongodb Cannot create container for service mongodb: error resolving passed in nfs address: lookup “40.133.27.228:/data/mongodata”: no such host

you sould always first try if the nfs mount actualy is working from the host:
mount -t nfs -o nfsvers={your nfs version} 4.1.2.2.:/mnt/netcool-mongodata /{your-mount-path-on-host}

Example for nfs4 and mount into /mtn:
mount -t nfs -o nfsvers=4 4.1.2.2.:/mnt/netcool-mongodata /mnt

Don’t forget to umount /mntwhen the test is finished.

Using nfs3 is NOT recommended!
