Chapter 3. Customizing Red Hat Developer Hub backend secret

Procedure

1. To define the Developer Hub backend secret, add to your custom my-rhdh-secrets.txt file the BACKEND_SECRET environment variable with a base64 encoded string. Use a unique value for each Developer Hub instance.

   $ echo > my-rhdh-secrets.txt "BACKEND_SECRET=$(node -p 'require("crypto").randomBytes(24).toString("base64")')"

   my-rhdh-secrets.txt example

   BACKEND_SECRET=3E2/rIPuZNFCtYHoxVP8wjriffnN1q/z

2. Add your backend secret to your custom app-config.yaml file.
