Persistent OpenAPI Key Issue in Langflow Deployment on Google Cloud

[eastnbull]

Hi everyone,
I have Langflow deployed as a Docker container in Google Cloud. I’ve configured an OpenAPI key as a credential in the system settings, which I use in my flows. However, the issue arises whenever the system is restarted by Google due to my current configuration. Each time this happens, I have to manually update the OpenAPI key in the settings for the flows to function. I’d greatly appreciate your assistance with this.

Hey @eastnbull! 👋 I'm here to help you with bugs, questions, and becoming a contributor. If you need assistance, feel free to ask!

To persist the OpenAPI key across system restarts in your Langflow deployment on Google Cloud, you can use environment variables. Langflow supports environment variables for managing credentials, including the OPENAI_API_KEY. You can set this environment variable in your Docker container configuration, ensuring it is automatically loaded each time the container starts.

Here's how you can do it:

1. Set the Environment Variable: Add the OPENAI_API_KEY to your Docker container's environment variables. You can do this in your docker-compose.yml file or directly in the Docker run command.

2. Use a .env File: If you're using Docker Compose, you can create a .env file to store your environment variables. Docker Compose will automatically load these variables when starting the container.

3. Configure Google Cloud: Ensure that your Google Cloud deployment is set up to pass these environment variables to the Docker container. This might involve setting environment variables in your Google Cloud configuration or using a secrets management service to securely store and inject them.

By setting the OPENAI_API_KEY as an environment variable, Langflow will automatically detect and use it as a global variable of type Credential, eliminating the need for manual updates after restarts ^[1].
