Nix Installation for Hermes Agent Container

Add these lines to the Dockerfile to bake Nix into the container image

--- ADD AFTER BASE IMAGE AND BEFORE USER SETUP ---

Install Nix (Determinate Systems installer)

This provides nix, nixos-rebuild, and the Nix package manager

RUN apt-get update && apt-get install -y --no-install-recommends
curl
xz-utils
&& rm -rf /var/lib/apt/lists/*

Download and run Nix installer (non-interactive)

RUN curl --proto '=https' --tlsv1.2 -sSf -L https://install.determinate.systems/nix
-o /tmp/nix-install.sh
&& chmod +x /tmp/nix-install.sh
&& sh /tmp/nix-install.sh install --no-confirm
&& rm /tmp/nix-install.sh

Configure Nix for flakes

RUN mkdir -p /root/.config/nix
&& echo 'experimental-features = nix-command flakes' > /root/.config/nix/nix.conf
&& echo 'substituters = https://cache.nixos.org/' >> /root/.config/nix/nix.conf

Add Nix to PATH for all users

ENV PATH="/nix/var/nix/profiles/default/bin:$PATH"

Optional: Expose Nix daemon socket if you want to use host's Nix (less secure)

VOLUME ["/nix/store"]

Note: Not recommended for security - builds run in container instead
