VKG not materialized in DMZ

The materialization of the whole VKG dump -- controlled by the env variable ONTOP_MATERIALIZATION = { blocking, nonblocking, none } -- is not working on DMZ servers.

The following error from the ontop/entrypoint.sh script appears (visible with blocking materialization):

"./entrypoint.sh: line 1: kill: (-1) - No such process"

The reason behind this error was not investigated, since the error is not reproduces in internal VMs + given the fencing done on DMZ with http/https proxy, the LICENSE file accompanying the dump was also not being downloaded (as the request was firewalled), this way opting for:

  • building of images outside of DMZ through the registry of the crisp-kg group
  • move the download of the LICENCE at build time in the ontop Dockerfile rather than in the entrypoint script that is executed when running the container.
