What is new in this version

  • All parameters were moved to input file, and usage of deploy_aks_cluster.py - changed
  • Microservices for test - installed automatically, by deploy_aks_cluster.py
  • Readme file updated

What is planning for next versions of Cluster installation application

  • Ingress configuration
  • Add references to Microsoft documentation, to code, to better understanding and maintenence (?)
  • More detailed readme file (?)
  • Split Cluster installation application to several files (?), as it's long and contains 10 Classes. Although code is easy for understanding if using PyCharm (or similar IDE).
