How to expose your app to the internet

June 10, 2024 11:14

In the ever-evolving landscape of web development and deployment, the manner in which applications are exposed to the internet plays a pivotal role in determining their accessibility, performance, and overall user experience. When deploying your application, you have the option to expose it to the internet using two different methods: CDN (Content Delivery Network) or Anycast.

What you'll need

Before you dive in, make sure you have the following prerequisites in place:

A bunny.net account (Log in or sign up for a free trial license).
Ensure that you have already set up the application you want to configure. See our Quickstart guide if you haven't set up an application yet.

CDN configuration

A CDN is a system of distributed servers that work together to deliver web content, such as images, videos, and scripts, to users based on their geographical location. It helps improve website performance, reduce latency, and enhance the overall user experience.

CDN can be used to create an Edge Endpoint through which containers of the application can be accessed. Any container running a process that is serving HTTP(S) traffic can be exposed using CDN.

NOTE: For more information about CDN, see our CDN documentation.

Configuration steps

To expose your app to the internet by using CDN configuration, follow the steps below:

1. Log in to your bunny.net account.

2. Navigate to the Magic Containers section and select the app from the dropdown menu you want to modify.

3. Click on Endpoints and Add New Endpoint.

4. Select CDN under the type.

You need to name the endpoint (it must have a unique name).
Specify the container port for every container.

NOTE: It is recommended to have one process running within a container. If multiple processes are running, ensure they operate on different ports.

Specify whether your application inside the container uses SSL for origin (this feature is only applicable for CDN).

5. Click Add Endpoint.

Anycast configuration

Anycast is a network addressing and routing methodology that enables multiple servers to share the same IP address. When a user makes a request, the network routes it to the nearest (in terms of network distance) Anycast node, improving performance and reliability.

The Anycast option will map containers to Anycast IP and expose it on the specified port.

NOTE: For more information about Anycast, see our Anycast documentation.

Configuration Steps

To expose your app to the internet by using Anycast configuration, follow the steps below:

1. Log in to your bunny.net account.

2. Navigate to the Magic Containers section and select the app from the dropdown menu you want to modify.

3. Click on Endpoints and Add New Endpoint.

4. Select Anycast under the type.

You need to name the endpoint (it must have a unique name).
Specify the Container Port for every container.
Define the Exposed Port, which is the port on which the application will be available on the Anycast IP.
When Anycast is selected, the platform will associate an Anycast IP. Specify the container port within the container and the exposed port to be used in combination with the Anycast IP to expose the application.

5. Click Add Endpoint.
