Docker retrieval error + Blazegraph question

[Laurent Fintoni]

Hi, 

I've done some searching in the groups but couldn't find any answers so am posting in the hopes someone might help.

I'm interesting in using Skosmos for a current project however am not able to install it locally. So i've been using the docker playground to test it and this is my first question:
- I've tried running Skosmos using both methods outlined here (the dockerfiles folder readme) and no matter what the build runs fine (available at 9090 port) but always returns "Error: Failed to retrieve vocabulary information!" when viewing the test vocabularies. I've also tried to build these with skosmos-2 branch in case and same issue. The triple store is available at 9030 however it always returns a 404 when accessed. 
- Am i missing something or is the fact that I'm using playground the issue? 

My second question regards running Skosmos with Blazegraph as the triplestore, which would likely be the preferred situation in terms of the IT support at my place of work. I found an old thread here detailing that it has never been official supported which is fine, just wondering if there are existing examples of installs or how to's that could help me better understand how to use them together.

Thank you!
