Codex¶

Description¶

Codex is OpenAI’s terminal coding agent, installed on a workstation and pointed at this deployment’s own model gateway instead of the vendor API.

Overview¶

The role installs the @openai/codex npm package at the version pinned in services.codex.npm_version and, when the workstation also runs svc-ai-litellm, writes a provider profile that sends every completion to the gateway over the loopback address the engine publishes it on. Nothing leaves the machine: the gateway answers on 127.0.0.1, so the workstation’s virtual key never crosses a network.

Codex reads its key from an environment variable rather than from its config file, so the role writes the key to a 0600 file under ~/.config/environment.d/ and names that variable in config.toml. A workstation whose gateway lives in another inventory leaves services.codex.gateway_url and credentials.gateway_key set by hand instead, and the loopback wiring stays out of the way.

Architecture¶

ARCHITECTURE.md draws Codex from its own metadata: the containers it runs under compose, what changes under swarm, how each volume is backed, and every role it depends on or is depended upon by.

Section	Drawn from
Compose	`meta/services.yml`
Swarm	`meta/services.yml` replicas and placement
Volumes	`meta/volumes.yml` against the NFS decision chain
Dependencies	`meta/services.yml` and `meta/main.yml` of every role

Features¶

Feature: Describe a capability.

Quick Setup¶

Development¶

Clone, set up the workstation, and deploy Codex onto the local stack:

git clone https://github.com/infinito-nexus/core.git
cd core
make onboard
make compose-deploy mode=reinstall apps=dsk-gnt-codex full_cycle=false

Production¶

Install Codex directly onto the target machine: clone the repository, install the OS prerequisites and the repository toolchain, then deploy against localhost over a local connection (no SSH, no container):

git clone https://github.com/infinito-nexus/core.git
cd core
bash scripts/install/package.sh
make install
source scripts/meta/env/load.sh

APP=dsk-gnt-codex
DOMAIN="<your-domain>"
TLS_MODE=self_signed
SSH_PUBLIC_KEY="<your-ssh-public-key>"
INVENTORY=inventories/production
infinito administration inventory provision "$INVENTORY" \
  --inventory-file "$INVENTORY/devices.yml" \
  --host localhost \
  --include "$APP" \
  --vars "{\"TLS_MODE\": \"$TLS_MODE\", \"DOMAIN_PRIMARY\": \"$DOMAIN\", \"users\": {\"administrator\": {\"authorized_keys\": [\"$SSH_PUBLIC_KEY\"]}}}"
infinito administration deploy dedicated "$INVENTORY/devices.yml" \
  --password-file "$INVENTORY/.password" \
  --diff -vv
