@Marvin I have a self hosted prefect, how do I add security to the API and UI?

To enhance security for your self-hosted Prefect API and UI, you can follow these steps: 1. Host the UI Behind a Reverse Proxy: Use a reverse proxy like Nginx or Traefik to manage traffic to your hosted Prefect UI instance. This setup can help manage SSL termination and provide an additional layer of security. Ensure that the

ui.api_url

in your

prefect.toml

file is set to the external proxy URL. 2. CSRF Protection: Implement CSRF protection by configuring appropriate settings in your server setup. This can help safeguard against cross-site request forgery attacks. 3. API Keys: Use API keys to authenticate requests to your Prefect API. You can set these up through your Prefect profiles using the

PREFECT_API_KEY

environment variable. 4. Database Security: Ensure your database connection is secure. Prefect supports SQLite and Postgres for self-hosted instances, and it's crucial to use secure connection strings. 5. Audit Logs and RBAC: While these features are more readily available in Prefect Cloud, you can implement similar mechanisms manually in a self-hosted environment to track access and manage roles. For more detailed guidance, refer to the Prefect documentation on self-hosting and security settings. If you're facing specific issues or need further customization, the Prefect GitHub repository might have relevant discussions or solutions. You can explore issues or raise new ones if needed. Feel free to ask if you have more specific questions or need deeper insights into any of these steps!

@Marvin how is my localhost is able to talk to the selfhosted prefect API without auth even though PREFECT_API_KEY env is already set?

Your localhost might be communicating with the self-hosted Prefect API without authentication because the

PREFECT_API_KEY

environment variable is primarily used for Prefect Cloud, not necessarily enforced in a self-hosted setup by default. Here are some considerations: 1. API Key Usage: The

PREFECT_API_KEY

is typically used to authenticate with Prefect Cloud. In a self-hosted environment, unless explicitly configured, the API might not require authentication, allowing local connections without an API key. 2. Configuration: Ensure that your self-hosted Prefect server is configured to require authentication. This might involve setting up an authentication layer or adjusting server settings to enforce API key checks. 3. Environment Variables: Double-check that the environment variables are correctly set and that the Prefect server is recognizing them. Sometimes, the server might not reload settings if they were changed after the server started. 4. Reverse Proxy Settings: If you're using a reverse proxy, ensure that it is configured to pass authentication headers correctly. For more details, you can explore the Prefect documentation on API keys and consider raising a GitHub issue if you suspect a bug or need further assistance with your setup. If you're facing persistent issues, you might want to explore GitHub discussions or raise a new issue for more tailored support.
