The __DATAHUB_TO_FILE_ directive is used in DataHub to handle sensitive data by specifying paths to files on a local file system. This directive is particularly useful when you need to include sensitive information, such as passwords, in your ingestion recipes without hardcoding them directly into the configuration files.

However, if you are encountering issues with the __DATAHUB_TO_FILE_password: "/mnt/secrets/mysql-password" not working, there are a few things you should check:

  1. File Existence and Permissions: Ensure that the file /mnt/secrets/mysql-password exists on the file system where the DataHub process is running. Also, verify that the file has the correct permissions set so that it can be read by the DataHub process.

  2. Correct Mounting: If you are using Kubernetes, make sure that the secret is correctly mounted as a volume in the pod. You can check this by inspecting the pod’s volume mounts and ensuring that the path /mnt/secrets/mysql-password is correctly mapped.

  3. Secret Configuration: According to the <https://github.com/datahub-project/datahub/blob/master/docs/managed-datahub/operator-guide/setting-up-remote-ingestion-executor.md|DataHub documentation>, secrets should be configured and mounted properly. Ensure that the secret is created and mounted as expected in your Kubernetes setup.

  4. Recipe Configuration: Double-check your ingestion recipe to ensure that the __DATAHUB_TO_FILE_ directive is used correctly. The syntax should be __DATAHUB_TO_FILE_<property>: <value>, where <property> is the configuration property you want to set, and <value> is the path to the file containing the secret.
