app.yaml environment variables substitution
View AAA README.md

This is a code snippet that reads an "app.yaml" file on stdin; then it:

  • seek for env_variables entry in the file
  • for each key: value pair, it looks for an environment variables named value
  • if it exists, it substitute the value with value found in the environment.

Exemple:

cat app.yaml
