  project_repo_url [https://github.com/python-microservices/microservices-scaffold]: 
  project_name [Python Microservices Boilerplate]: example project
  project_folder [example_project]: 
  project_short_description [Python Boilerplate contains all the boilerplate you need to create a Python package.]:

• Encrypt/decrypt config (#86)

  • New encryption and decryption feature with AES
  • Create a key to encrypt config with new command line pyms create-key
  • Encrypt a string with the new command line pyms encrypt [STRING]
  • Set the key file with new environment variable KEY_FILE
  • If you set in your config a var with the prefix "ENC_" or "enc_" PyMS search for the key file and decrypt the string. Now you can encrypt your database url for production environments. I.E.:

  pyms:
  [...]
  config:
  ENC_DATABASE: gAAAAABeSZ714r99iRIxhoH77vTdRJ0iqSymShfqgGN9PJveqhQWmshRDuV2a8sATey8_lHkln0TwezczucH-aJHGP_LyEiPxwM-88clNa7FB1u4g7Iaw3A=

  you can access it in your code with current_app.config["DATABASE"] == "http://database-url"

• Human readable config errors #85
  Show more help information if the config file not have a good structure with error messages like

  Config file must start with `pyms` keyword, for example:
  pyms:
    services:
    metrics: true
    requests:
    data: data
    swagger:
    path: ""
    file: "swagger.yaml"
    tracer:
    client: "jaeger"
    host: "localhost"
    component_name: "Python Microservice"
    config:
    DEBUG: true
    TESTING: true
  

• Add service name label by default #84 - @alexppg
  It adds a label to all jaeger's generated metrics that can be used to identify every microservice.
  See jaegertracing/jaeger-client-python#269.
  I messed up the previous PR, it's the same as this. #72

Fixes

• Send path to ConfFile from Microservice class to set path from code if you want to not use CONFIGMAP_FILE from env

Refactors

• Refactor config. Memoize of files moved to new class
