globals is a virtual manifest in the infra category. It owns stack-wide settings and runs no container. Its variables appear at the top of the generated .env.example.

./start.sh and ./stop.sh read these values from .env. The compose fragments use them for the project namespace, port binds, host-gateway mapping, GPU visibility and log rotation.

globals has no Kong alias and no port of its own. BASE_PORT is the base from which every service *_PORT derives.

Variable	Default	Purpose
PROJECT_NAME	atlas	Compose project name and the prefix for containers, volumes and networks. ./stop.sh uses it to stop what ./start.sh started. Set a unique name when Atlas runs as a submodule.
BASE_PORT	63000	Base port. Every service *_PORT is this value plus a fixed offset.
HOST_BIND_IP	127.0.0.1:	Host interface prefix for all published ports. Keep the trailing colon. Set 0.0.0.0: only for deliberate remote access.
HOST_GATEWAY_IP	host-gateway	Target of host.docker.internal. ./start.sh computes it: host-gateway on Docker, the gateway IP on Podman.
BRAND_NAME, BRAND_TAGLINE, BRAND_VERSION, BRAND_AUTHOR, BRAND_AUTHOR_EMAIL, BRAND_LICENSE, BRAND_REPO_URL	Atlas values	Brand metadata in the wizard and the --no-tui banner.
BRAND_LOGO_FILE	empty	Path to a custom block-art logo. Empty uses the built-in ATLAS lockup.
COMPOSE_PROFILES	empty	Compose profile list. ./start.sh rebuilds it on every run from the STT, TTS and doc-processor sources. Do not edit it.
NVIDIA_VISIBLE_DEVICES	all	Host GPU visibility for NVIDIA-runtime containers.
PROD_ENV_CPUS, PROD_ENV_MEM_LIMIT, PROD_ENV_BACKEND_*, PROD_ENV_N8N_*	2, 8g, 1/2g, 1/2g	Reserved resource caps. No compose fragment reads them yet.
PROD_ENV_COMFYUI_CPUS, PROD_ENV_COMFYUI_MEM_LIMIT	2, 4g	CPU and memory caps for the ComfyUI container-gpu source.
LOG_MAX_SIZE, LOG_MAX_FILE	10m, 3	Docker json-file log size and file count per container.
BOOTSTRAPPER_PORT_LAYOUT_VERSION	5	Migration sentinel. A missing or lower value runs the chained .env migrations.

The environment variable reference has the full descriptions.

globals has no dependencies and no runtime calls.

globals has no SOURCE variable. It is always active.

Compose fragments bind published ports as ${HOST_BIND_IP-127.0.0.1:}. An unset variable binds loopback; an explicitly empty value binds all interfaces. Exceptions: Ray, Zeppelin and mcp-servers always bind 127.0.0.1. Supabase DB, Docling and Parakeet use ${HOST_BIND_IP:-127.0.0.1:}, so an empty value also binds loopback there.

• Change the project name: ./start.sh --project <name> (or -p). The value is written back to .env.
• Change the base port: ./start.sh --base-port <port> or --base-port auto.
• Stop the project: ./stop.sh.

• Service manifest: services/globals/service.yml
• Generated environment template: .env.example

Support tier: experimental — Capability contract declared; no cited cold-start, workflow, or upgrade qualification run yet (evidence at v0.1.0).

Capability	Status	Verification	Notes
Project namespace and base-port ownership	supported	tested	This virtual manifest owns the Compose project namespace, the bind and gateway settings, and the base port from which service ports derive. It launches no container of its own.
Branding and launch defaults	supported	tested	Atlas assembles the brand metadata, Compose profiles, GPU reservation flags, and shared logging defaults declared here into the generated environment.
Generic production resource limits	partial	documented	The PROD_ENV limit variables are reserved shared configuration, but most service compose fragments do not yet consume them as generic runtime caps.
