Deploy the material-agent-service locally using Docker Compose with OVRTX rendering. Use when user wants to run material agent with docker, docker compose, set up local deployment, run the service locally with GPU rendering, start material agent containers, or configure VLM provider for docker deployment. Trigger phrases include "docker compose", "docker deploy", "run locally with docker", "start material agent docker", "docker up", "local deployment", "compose up".
Requires Docker daemon, Docker Compose v2.24+, NVIDIA Container Toolkit, an RTX-class GPU with 48GB+ VRAM for local OVRTX rendering, repo-root .env provider credentials, and free host ports 8000/8001.
Deploy Material Agent Service with Docker Compose
Deploy the material-agent-service and OVRTX rendering API locally using Docker Compose. No NGC login or Kubernetes required for the default setup.
When to Use
Use when the user wants to run material-agent-service locally with Docker Compose.
Use when the user needs the bundled OVRTX rendering API sidecar on a GPU host.
Use when the user wants to configure cloud VLM providers or an optional local VLM NIM sidecar for Material Agent.
Use quickstart for a shorter first local POC, and use deploy-collection when running multiple Content Agents together with shared dependency endpoints.
Limitations
The default stack owns host ports 8000 and 8001. Stop overlapping Material, Physics, Texture, or standalone OVRTX stacks before startup.
Local OVRTX rendering needs an RTX-class GPU with about 48GB+ VRAM; A100/H100/H200/V100 are not supported for this path.
First build and first render are long-running operations. Start Compose normally, then return logs and health commands instead of holding an agent session open indefinitely.
Keep secrets out of chat and commits. Tell the user to edit .env; do not ask them to paste keys.
Prerequisites
Check before deploying:
Docker Compose v2.24+: docker compose version -- required for env_file: required: false long-form syntax
RTX-capable NVIDIA GPU with 48GB+ VRAM for local OVRTX rendering
(L40, L40S, RTX PRO 6000, etc.; not A100/H100/H200/V100): nvidia-smi
NVIDIA Container Toolkit installed: docker run --rm --gpus all nvidia/cuda:12.0-base nvidia-smi
VLM provider API key (at least one): OpenAI, Anthropic, Gemini, or NVIDIA
Image generation key (optional): public default is Gemini, so set GOOGLE_API_KEY if the user plans to use generated reference images or generated material-library textures. Otherwise set MA_IMAGE_GEN_BACKEND to another configured provider.
Instructions
Confirm Docker, Compose, GPU, NVIDIA Container Toolkit, and port availability before starting the stack.
Create or update the repo-root .env with exactly the provider credentials the selected backend needs.
Start the Material Agent compose stack from the repo root.
Wait for both the main service and OVRTX readiness checks before reporting the service ready.
Return service URLs, health state, log commands, and stop commands using the output format below.
Set VLM API Key
Create .env at the repo root (the compose file reads it via env_file: ../../.env):
To run Cosmos Reason2 8B locally instead of using a cloud VLM API:
# NGC login required for VLM NIM imageprintf'%s'"$NGC_API_KEY" | docker login nvcr.io \
--username '$oauthtoken' --password-stdin
# Add NGC_API_KEY to .env for model weight downloadecho'NGC_API_KEY=...' >> .env# Start with vlm profile + multi-gpu overlay# The overlay pins ovrtx-rendering-api to GPU 0 and vlm-nim to GPU 1.# It is REQUIRED here: NIM's profile selector reports "Free GPUs: <None>"# and refuses to launch when ovrtx is also holding a GPU, even with tens# of GB free. See docker-compose.multi-gpu.yml for the pinning details.
docker compose \
-f apps/material_agent_service/docker-compose.yml \
-f apps/material_agent_service/docker-compose.multi-gpu.yml \
--profile vlm up --build
Requires 2 GPUs (48GB each). VLM NIM takes ~15 minutes to start (model compilation).
The multi-gpu overlay also routes MA_VLM_* and MA_LLM_* to the local
vlm-nim sidecar (nvidia/cosmos-reason2-8b), so no extra .env edits
are needed for --profile vlm.

raise SystemExit(1)
if health.get("gpu_initialized") is True:

The CPU and memory limits above are the explicit material-agent-service limits in apps/material_agent_service/docker-compose.yml. ovrtx-rendering-api and vlm-nim reserve GPUs but do not define CPU or memory limits in the compose files, so size the host with additional headroom for those sidecars.
GPU Configuration
To assign more GPUs to the rendering API, edit docker-compose.yml:
ovrtx-rendering-api:deploy:resources:reservations:devices:-driver:nvidiacount:2# number of GPUscapabilities: [gpu]
Or assign specific GPU IDs:
device_ids: ['0', '1']

VLM NIM context length (for 48GB GPUs)
Prediction concurrency is set per request with vlm_max_workers; it is not a
service-wide environment variable.
Generated reference images and generated material-library mode are optional. If
enabled from the client or UI, the service uses MA_IMAGE_GEN_BACKEND=gemini
by default.
Output Format
When handing control back to the user, report:
SERVICE_URL: http://localhost:8000
DOCS_URL: http://localhost:8000/docs
SERVICE_HEALTH: healthy, starting, or unhealthy
OVRTX_HEALTH: healthy only when /health contains "gpu_initialized":true; otherwise warming or unhealthy
If shader compilation messages appear, wait ~5 minutes (first-time only).
Main service unhealthy before rendering API ready
The main service depends_on the rendering API health check. If rendering takes long to start (shader compilation), increase start_period in docker-compose.yml.
