Context
We use Nix to build our project reproducibly, including the github-pages documentation. This setup is also used in our CI to build the github-pages which are eventually deployed. Nix prohibits network connections (except if the output hash is specified, which is unpractical in this case) because the network is not reproducible. However, in some circumstances (e.g., the default installation on macOS) the Nix sandbox is disabled or weakened. Hence, github-metadata accesses the network which results in failing builds or differing outputs.
Feature Request
We would like to reliably disable network accesses without actually disabling the network.
Implemented solution
Network accesses are skipped if the environment variable
PAGES_DISABLE_NETWORK
is set.Related issues
