OpenSSL and node-gyp errors when using a docker image built by `nix build` with a flake

Help

For the issue in the first approach (SSL errors), it looks fixed by adding this in the docker configuration:

config = {
  User = "foo";
  WorkingDir = "/app";
  Env = ["SSL_CERT_FILE=${pkgs.cacert}/etc/ssl/certs/ca-bundle.crt"];
};

After adding this, and creating the /tmp directory during the image setup, running nix develop worked inside the docker container. Also there were no errors when cloning the git repository. So with that I can reuse the same flake setup packages inside the container.

However, for the node-gyp issue, I haven’t been able to fix it yet. I will comment if I find a solution. It looks like it is possible to install with npm install --ignore-scripts, but that skips building some required modules. Running the JS file directly with ./node_modules/.bin/gatsby doesn’t work due to the shebang inside that file: #!/usr/bin/env node, since usr/bin/env doesn’t exist inside the container (but it exists in the host NixOS). If I run node ./node_modules/.bin/gatsby, it has some other issues (it is missing a module that is built during installation).
