JSON in YAML settings Google Cloud App Engine

Question

I'm deploying an app through gcloud on App Engine. There is an env.yaml file that I need to modify, then I upload it in a bucket, the file contains the settings and secrets:

env_variables:
  DB_URL: XXX
  URL: YYY
  JSON_SETTINGS: '{"api": {"secret":"mySecret"}}'

There are hundred of settings in JSON_SETTINGS, and for the deployment to work I have to send it on one line. But it's not handy.

When I use a formatter to expand the JSON, I got an error : googlecloudsdk.api_lib.app.yaml_parsing.YamlParseError: An error occurred while parsing file

Do you have any idea how to handle it?

I'm not sure I understand the problem.

Your YAML should be good.

By quoting the JSON_SETTINGS, the JSON is treated as the value. Why must it be a single line? Why are you using a JSON formatter on YAML?

Couple of things:

You can use a block delimiter in YAML. A paragraph (|). As in JSON_SETTINGS: | and then the JSON content indented (!) and starting on the line be below. You can then layout over multiple lines.

You can also use "\"x\": \"something\"" to escape too.
