About forwarded ports

Port forwarding gives you access to TCP ports running within your codespace. For example, if you're running a web application on port 4000, you can access the application from your browser to test and debug the application.

When an application running inside a codespace outputs a port to the console, {% data variables.product.prodname_codespaces %} detects the localhost URL pattern and automatically forwards the port. You can click on the URL in the terminal to open the port in a browser. For example, if an application outputs http://127.0.0.1:4000 or http://localhost:4000 to the console, the log would automatically convert the output to a clickable URL for port 4000. By default, {% data variables.product.prodname_codespaces %} forwards ports using HTTP.

You can also forward a port manually, label forwarded ports, share forwarded ports with members of your organization, share forwarded ports publicly, and add forwarded ports to the codespace configuration.

Forwarding a port

You can manually forward a port that wasn't forwarded automatically.

{% data reusables.codespaces.navigate-to-ports-tab %}

1. Under the list of ports, click Add port.
2. Type the port number or address, then press enter.

Using HTTPS forwarding

By default, {% data variables.product.prodname_codespaces %} forwards ports using HTTP but you can update any port to use HTTPS, as needed.

{% data reusables.codespaces.navigate-to-ports-tab %}

1. Right click the port you want to update, then hover over Change Port Protocol.
2. Select the protocol needed for this port. The protocol that you select will be remembered for this port for the lifetime of the codespace.

Labeling a port

You can label a port to make the port more easily identifiable in a list.

{% data reusables.codespaces.navigate-to-ports-tab %}

1. Hover over the port you want to label, then click the label icon. {% data reusables.codespaces.type-port-label %}

Sharing a port

{% note %}

Note: You can only make a port private to an organization if your organization uses {% data variables.product.prodname_team %} or {% data variables.product.prodname_ghe_cloud %}. This feature is not currently available in the beta version of {% data variables.product.prodname_codespaces %}.

{% endnote %}

If you want to share a forwarded port with others, you can either make the port private to your organization or make the port public. After you make a port private to your organization, anyone in the organization with the port's URL can view the running application. After you make a port public, anyone with the port's URL can view the running application without needing to authenticate.

{% data reusables.codespaces.navigate-to-ports-tab %}

1. Right click the port that you want to share, select the "Port Visibility" menu, then click Private to Organization or Public.
2. To the right of the local address for the port, click the copy icon.
3. Send the copied URL to the person you want to share the port with.

Adding a port to the codespace configuration

You can add a forwarded port to the {% data variables.product.prodname_codespaces %} configuration for the repository, so the port will automatically be forwarded for all codespaces created from the repository. After you update the configuration, any previously created codespaces must be rebuilt for the change to apply. For more information, see "Configuring {% data variables.product.prodname_codespaces %} for your project."

You can manually configure forwarded ports in a .devcontainer.json file using the forwardPorts property, or you can use the "Ports" panel in your codespace.

{% data reusables.codespaces.navigate-to-ports-tab %}

1. Right click the port you want to add to the codespace configuration, then click Set Label and Update devcontainer.json. {% data reusables.codespaces.type-port-label %}
