具有NFS安装作为卷映射的SQL Server Docker容器

Question

I am trying to run SQL Server on ubuntu as a docker container using stranded microsoft/mssql-server-linux:latest docker image. For the data persistence I am mapping a volume from my host (having ext4 file system) to container using -v option in docker run command like below

docker run -it -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=######' -p 1433:1433 
               -v /var/opt/database:/var/opt/mssql/data microsoft/mssql-server-linux

Container is running just fine and i am able to connect to the database. But I do not want to store data on my host because of the growing size of the database and for swarm reasons. Now I thought to run a NFS server on some other machine and mount the nfs directory onto my docker host and then use that nfs dir on the volume mapping now the volume mapping is

-v /var/nfs/database:/var/opt/mssql/data 

where /var/nfs/database is a nfs mount dir on the docker host. Now when I start the container I get the following error

2017-08-18 10:15:53.98 spid5s FCB::Open failed: Could not open file /var/opt/mssql/data/master.mdf for file number 1. OS error: 87(The parameter is incorrect.). 2017-08-18 10:15:53.98 spid5s Error: 5120, Severity: 16, State: 101. 2017-08-18 10:15:53.98 spid5s Unable to open the physical file "/var/opt/mssql/data/master.mdf". Operating system error 87: "87(The parameter is incorrect.)". 2017-08-18 10:15:54.13 spid5s Error: 17204, Severity: 16, State: 1. 2017-08-18 10:15:54.13 spid5s FCB::Open failed: Could not open file /var/opt/mssql/data/mastlog.ldf for file number 2. OS error: 87(The parameter is incorrect.). 2017-08-18 10:15:54.13 spid5s Error: 5120, Severity: 16, State: 101. 2017-08-18 10:15:54.13 spid5s Unable to open the physical file "/var/opt/mssql/data/mastlog.ldf". Operating system error 87: "87(The parameter is incorrect.)".

I have given all the permissions to database files. Below is the nfs mount snippet

sharedstorageIp:/var/nfs nfs4 443G 47G 375G 11% /var/nfs

The release notes explain that you can't do this:

Hosting database files on a NFS server is not supported in this release. This includes using NFS for shared disk failover clustering as well as databases on non-clustered instances. We are working on enabling NFS server support in the upcoming releases.

Hosting database files on a networked path is not trivial, given the demands the database has for reliability. Hosting files on SMB shares wasn't possible until version 2.2 of the protocol.
