Environment Variables

Environment variables

You can add environment variables to your manifest files, either globally or per environment. For example:

environment_variables:
  SOME_VARIABLE: value
  ANOTHER_ONE: another_value
  THIRD_ONE: AUTO_GENERATE
  LONG_ONE: AUTO_GENERATE_15

If you need to auto generate a value, you can use the AUTO_GENERATE keyword. It generates a 10 character long random string unless you specify the length after it: AUTO_GENERATE_15 which generates a 15 character random string.

Environment variables set in your manifest file will only apply during the initial build of your application. Please refer to our documentation on environment variables if you'd like to set them beyond this point.

Any environment variable that is generated by the result of the code analysis (like database addresses) will override any value specified in the manifest file. In other words, you cannot specify a value like MYSQL_ADDRESS in your manifest file as it will be ignored.

Per-environment variables

You can also specify environment variables for specific environments:

production:
  environment_variables:
    SOME_VARIABLE: production_value
    API_ENDPOINT: https://api.production.example.com

staging:
  environment_variables:
    SOME_VARIABLE: staging_value
    API_ENDPOINT: https://api.staging.example.com

Important Notes

• Environment variables in the manifest only apply during the initial build
• System-generated variables (like MYSQL_ADDRESS) cannot be overridden
• Use AUTO_GENERATE for secure random values
• For runtime environment variable management, use the Cloud 66 Dashboard or Toolbelt
