building base image dockerjava8 fails

[tomas321]

PROBLEM:

• fails on building cryptography (as the docker-compose pip package dependency)

error message snippet:

  error: command 'gcc' failed with exit status 1
  ----------------------------------------
  ERROR: Failed building wheel for cryptography

Failed to build cryptography
ERROR: Could not build wheels for cryptography which use PEP 517 and cannot be installed directly

FIX:

• by modifying the Dockerfile with preinstalling cryptography==2.8, the issue is solved
  • I chose this version as it was the latest version at the time of last change of the dockerjava8/Dockerfile
