Hi,

I'm trying to deploy this file on an internal kubernetes cluster, but I'm facing this error:
persistentvolumeclaim "family-init-vol-claim" not found.

Note: my file is the basically the same, I just had to comment the line 70 out and add the resources quotas for the containers.

Hi @rppala3. Thanks for reading.

I'm not sure how you got here but this gist was created to support this article. The family-init-vol-claim is a pre-prepared pvc that contains data and scripts to initialize the server directories. It's mentioned in the article in the following paragraph:

We will also use a pre-populated Elastic File System (EFS) volume containing the data to be loaded into each replica during the initialisation stage.

It's contents are also described in a little bit more detail later in the article.

Things have moved on since that article was published though and RDFox now supports high-availability for read/write services. If you'd like to know more, please contact us at info@oxfordsemantic.tech and reference this post.
