 If you used any of the EDB Postgres AI Hybrid Manager `-install-secrets.sh` scripts to set up your environment, you may already have a Fernet key generated. If not, you can generate one using the following command in your terminal. Ensure you have `kubectl` configured to point to your EDB Postgres AI Hybrid Manager cluster:
