  +
  +Some properties are arrays. For example:

  +----
  +analytics:
  +  elasticsearch:
  +    endpoints:

  +      - https://my.second.endpoint.com
  +
  +security:
  +  providers:
  +    - type: ldap
  +      context-source-username: "cn=Directory Manager"
  +      context-source-password: "password"
  +----
  +
  +Here is the way to write your environment variables:
  +
  +----
  +gravitee_analytics_elasticsearch_endpoints_0=https://my.first.endpoint.com
  +gravitee_analytics_elasticsearch_endpoints_1=https://my.second.endpoint.com
  +
  +gravitee_security_providers_0_type=ldap
  +gravitee_security_providers_0_context-source-username=cn=Directory Manager
  +gravitee_security_providers_0_context-source-password=password
