The Elixir release's start script reads releases/COOKIE which isn't baked in, so the service crashed on boot (cat: releases/COOKIE: No such file). Set RELEASE_COOKIE in the systemd Environment to fix startup.

# NixOS module for the n8n OpenAI-compatible adapter.

#
|
|
# Consume from config-nixos:
|
|
# imports = [ inputs.n8n-openai-adapter.nixosModules.default ];
|
|
# services.n8n-openai-adapter = {
|
|
# enable = true;
|
|
# domain = "openai.bueso.eu";
|
|
# port = 8134;
|
|
# };
|
|
#
|
|
# The module defines the systemd service, the service user, and the sops secret
|
|
# (`n8n_openai_env` carrying ADAPTER_API_KEY + AGENTS). The nginx vhost is NOT
|
|
# defined here — add it in the consuming config (config-nixos has its own
|
|
# nginx.nix with ACME/SSL). This keeps the flake self-contained for the service
|
|
# while the site exposure stays a deployment concern.
