How do I add master.key to a rails app deployed directly from github with app platform?

The master.key is never committed to source control for security purposes but how can i make it available to the digital ocean app platform to decrypt the credentials.yml.enc.

Adding the contents of your master.key file to a environment variable then prepending your run command with something like:

echo "${MASTER_KEY}" > master.key && <your_original_build_command>

This assumes that your env var is called “MASTER_KEY”

This will cause the contents of the env var to put in a file called master.key before your app is run.
