Test Orbit mTLS

WARNING: All of these scripts are for testing only, they are not safe for production use.

Following is a guide to help you run and test Orbit with TLS client certificate authentication.

All commands are executed in the repository's root directory. All commands were tested on an Intel macOS.

The nginx proxy is configured to authenticate all TLS requests with the provided client_ca.crt.

1. Setup

This guide assumes the following Local TUF setup.

2. Start nginx proxy with client certificate verification

docker compose -f ./tools/test-orbit-mtls/docker-compose.yml up

The proxy will listen to port 8888 and use TLS client certificates for authentication.

Note: If you would like to use a public URL, see public mTLS reverse proxy instructions

3. Generate Orbit installers with custom flags

rm -rf test_tuf

We need to define FLEET_DESKTOP_ALTERNATIVE_BROWSER_HOST because we are not expecting users to configure client certificates on their browser.

Once the packages are generated, they are ready to be installed on devices for testing.
