-In k8s environments secrets can be injected in a running workload as an environment variable,
-as a standalone file or a INI key in a standalone file. Such secrets may be base64 encoded.
-
-_Data Catalog Agent_ configuration supports referencing such secrets inline in selected fields of the
-JSON configuration file. When the field supports secrets you may write a plain string or objects.
-
-In case of a string the secret is considered `plain` and written in the config file.
-In case of an object with `env` guard like:
-
-```json
-{
-  "type": "env",
-  "key": "MY_SECRET_ENV_VAR"
-}
-```
-
-the agent will use the content of the env var `MY_SECRET_ENV_VAR`. An extra `encoding` field equal
-to `base64` can be used to specify a pre-read decoded to use.
