Shiny, new domain is much better and eliminates the TLS redirect issue
because there is a HSTS preload for the entire .dev TLD (which, by the
way, is awesome!)
Adds git & SSH as part of the Nixery image, which are required to use
Nix's builtins.fetchGit.
The dependency on interactive tools is dropped, as it was only
required during development when debugging the image building process
itself.
When running on AppEngine, the image is expected to be configured with
a default entry point / command.
This sets the command to the wrapper script, so that the image can
actually run properly when deployed.
When running Nix inside of a container image, there are several
environment-specific details that need to be configured appropriately.
Most importantly, since one of the recent Nix 2.x releases, sandboxing
during builds is enabled by default. This, however, requires kernel
privileges which commonly aren't available to containers.
Nixery's demo instance (for instance, hehe) is deployed on AppEngine
where this type of container configuration is difficult, hence this
change.
Specifically the following were changed:
* additional tools (such as tar/gzip) were introduced into the image
because the builtins-toolset in Nix does not reference these tools
via their store paths, which leads to them not being included
automatically
* Nix sandboxing was disabled in the container image
* the users/groups required by Nix were added to the container setup.
Note that these are being configured manually instead of via the
tools from the 'shadow'-package, because the latter requires some
user information (such as root) to be present already, which is not
the case inside of the container
Introduces a wrapper script which automatically sets the paths to the
required runtime data dependencies.
Additionally configures a container image derivation which will output
a derivation with Nixery, Nix and other dependencies.
Rather than migrating to Bazel, it seems more appropriate to use Nix
for this project.
The project is split into several different components (for data
dependencies and binaries). A derivation for building an image for
Nixery itself will be added.
