Yes, the configuration for setting the URL is the same for the open-source version of Airbyte. The

WEBAPP_URL

environment variable is used in both Airbyte Cloud and Airbyte Open Source to define the URL where the Airbyte Webapp is hosted. For the open-source version, you would still set the

WEBAPP_URL

as described earlier: 1. For Docker-based deployments: Set the environment variable

WEBAPP_URL=<https://www.example.com>

in your Docker Compose file or when running the Docker container. 2. For Kubernetes deployments using Helm: In your

values.yaml

file, set:

yaml    global:      airbyteUrl: <https://www.example.com>

This configuration applies to the open-source version as well, allowing you to customize the URL for your Airbyte instance when it's deployed behind a load balancer. It's worth noting that while the URL configuration is the same, the open-source version has some differences in terms of security features. For example, the open-source version doesn't include built-in user management or role-based access controls (RBAC). You would need to implement additional security measures, such as deploying Airbyte in a private network or using a firewall to control access.

Based on the information provided in the knowledge sources and your question, I can offer some insights into why Airbyte might still be working despite setting an incorrect

WEBAPP_URL

. 1. Default behavior: Airbyte has a default configuration that allows it to function even if the

WEBAPP_URL

is not set correctly. This is likely a fallback mechanism to ensure the application can still run locally. 2. Local deployment: When deploying Airbyte locally, it typically defaults to using

<http://localhost:8000>

as the base URL. This allows the application to function on your local machine regardless of the

WEBAPP_URL

setting. 3. Configuration precedence: The

WEBAPP_URL

setting in

values.yaml

might not be taking precedence over the default configuration in a local deployment scenario. 4. Internal routing: For local deployments, Airbyte's internal services might be communicating using container names or internal network addresses, which would work regardless of the external URL setting. However, it's important to note that while Airbyte may appear to be working, setting an incorrect

WEBAPP_URL

could potentially cause issues with certain features, especially those related to external access or notifications. To ensure proper configuration, for a local deployment, you should set

WEBAPP_URL

to

<http://localhost:8000>

(assuming you're using the default port) rather than

<https://localhost.com>

. If you're trying to test the behavior with a custom domain, you would need to actually set up that domain to point to your local machine and configure your local environment accordingly. [Source: Airbyte Documentation](https://docs.airbyte.com/operator-guides/configuring-airbyte#airbyte-services) If you're experiencing unexpected behavior or if you need to test specific URL-dependent features, I recommend reaching out to the Airbyte community or support channels for more detailed assistance, as the provided knowledge sources don't contain enough information to fully explain this specific scenario.
