Provide support for LDF servers

[antru6]

Apart from Virtuoso and Strabon, a federation could also include LDF servers.

Hi @antru6, the Endpoints can load and serve data correctly!
But when I tried to launch an experiment, I received an error message (see below).

MountVolume.SetUp failed for volume "nfs-in-drugbank" : mount failed: exit status 32 Mounting command: mount Mounting arguments: -t nfs 172.17.0.2:/exports/drugbank/dump /var/lib/kubelet/pods/a5a8665a-aef8-4d18-8184-b511a5cfef21/volumes/kubernetes.io~nfs/nfs-in-drugbank Output: mount.nfs: mounting 172.17.0.2:/exports/drugbank/dump failed, reason given by server: No such file or directory

I found there is a dump.nt file in the "/exports/drugbank/" directory, but no dump directory. Can you please help with it?

Hi @chengsijin0817, thanks for pointing out this. I have made a slight modification to the template, please fetch the new version of the branch, and give it one more try. I have also tested the endpoints myself.
Please give us some info to reproduce your experiment, should the problem persists.

Hi @antru6, many thanks for your quick response. The issue is fixed now!
I simply rebuild the Docker image 'ldfserver-init' and 'ldfserver-main' with the latest version of Docker files, and it works.
