# What does this PR do? start_stack.sh was using --yaml-config which is deprecated. a bunch of distro docs also mentioned --yaml-config. Replaces all instances and logic for --yaml-config with --config resolves #2189 Signed-off-by: Charlie Doern <cdoern@redhat.com>

|
|
|
|
The `llamastack/distribution-tgi` distribution consists of the following provider configurations.
|
|
|
|
| API | Provider(s) |
|
|
|-----|-------------|
|
|
| agents | `inline::meta-reference` |
|
|
| datasetio | `remote::huggingface`, `inline::localfs` |
|
|
| eval | `inline::meta-reference` |
|
|
| inference | `remote::tgi`, `inline::sentence-transformers` |
|
|
| safety | `inline::llama-guard` |
|
|
| scoring | `inline::basic`, `inline::llm-as-judge`, `inline::braintrust` |
|
|
| telemetry | `inline::meta-reference` |
|
|
| tool_runtime | `remote::brave-search`, `remote::tavily-search`, `inline::rag-runtime`, `remote::model-context-protocol` |
|
|
| vector_io | `inline::faiss`, `remote::chromadb`, `remote::pgvector` |
|
|
|
|
|
|
You can use this distribution if you have GPUs and want to run an independent TGI server container for running inference.
|
|
|
|
### Environment Variables
|
|
|
|
The following environment variables can be configured:
|
|
|
|
- `LLAMA_STACK_PORT`: Port for the Llama Stack distribution server (default: `8321`)
|
|
- `INFERENCE_MODEL`: Inference model loaded into the TGI server (default: `meta-llama/Llama-3.2-3B-Instruct`)
|
|
- `TGI_URL`: URL of the TGI server with the main inference model (default: `http://127.0.0.1:8080/v1`)
|
|
- `TGI_SAFETY_URL`: URL of the TGI server with the safety model (default: `http://127.0.0.1:8081/v1`)
|
|
- `SAFETY_MODEL`: Name of the safety (Llama-Guard) model to use (default: `meta-llama/Llama-Guard-3-1B`)
|
|
|
|
|
|
## Setting up TGI server
|
|
|
|
Please check the [TGI Getting Started Guide](https://github.com/huggingface/text-generation-inference?tab=readme-ov-file#get-started) to get a TGI endpoint. Here is a sample script to start a TGI server locally via Docker:
|
|
|
|
```bash
|
|
export INFERENCE_PORT=8080
|
|
export INFERENCE_MODEL=meta-llama/Llama-3.2-3B-Instruct
|
|
export CUDA_VISIBLE_DEVICES=0
|
|
|
|
docker run --rm -it \
|
|
--pull always \
|
|
-v $HOME/.cache/huggingface:/data \
|
|
-p $INFERENCE_PORT:$INFERENCE_PORT \
|
|
--gpus $CUDA_VISIBLE_DEVICES \
|
|
ghcr.io/huggingface/text-generation-inference:2.3.1 \
|
|
--dtype bfloat16 \
|
|
--usage-stats off \
|
|
--sharded false \
|
|
--cuda-memory-fraction 0.7 \
|
|
--model-id $INFERENCE_MODEL \
|
|
--port $INFERENCE_PORT
|
|
```
|
|
|
|
If you are using Llama Stack Safety / Shield APIs, then you will need to also run another instance of a TGI with a corresponding safety model like `meta-llama/Llama-Guard-3-1B` using a script like:
|
|
|
|
```bash
|
|
export SAFETY_PORT=8081
|
|
export SAFETY_MODEL=meta-llama/Llama-Guard-3-1B
|
|
export CUDA_VISIBLE_DEVICES=1
|
|
|
|
docker run --rm -it \
|
|
--pull always \
|
|
-v $HOME/.cache/huggingface:/data \
|
|
-p $SAFETY_PORT:$SAFETY_PORT \
|
|
--gpus $CUDA_VISIBLE_DEVICES \
|
|
ghcr.io/huggingface/text-generation-inference:2.3.1 \
|
|
--dtype bfloat16 \
|
|
--usage-stats off \
|
|
--sharded false \
|
|
--model-id $SAFETY_MODEL \
|
|
--port $SAFETY_PORT
|
|
```
|
|
|
|
## Running Llama Stack
|
|
|
|
Now you are ready to run Llama Stack with TGI as the inference provider. You can do this via Conda (build code) or Docker which has a pre-built image.
|
|
|
|
### Via Docker
|
|
|
|
This method allows you to get started quickly without having to build the distribution code.
|
|
|
|
```bash
|
|
LLAMA_STACK_PORT=8321
|
|
docker run \
|
|
-it \
|
|
--pull always \
|
|
-p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
|
|
llamastack/distribution-tgi \
|
|
--port $LLAMA_STACK_PORT \
|
|
--env INFERENCE_MODEL=$INFERENCE_MODEL \
|
|
--env TGI_URL=http://host.docker.internal:$INFERENCE_PORT
|
|
```
|
|
|
|
If you are using Llama Stack Safety / Shield APIs, use:
|
|
|
|
```bash
|
|
# You need a local checkout of llama-stack to run this, get it using
|
|
# git clone https://github.com/meta-llama/llama-stack.git
|
|
cd /path/to/llama-stack
|
|
|
|
docker run \
|
|
-it \
|
|
--pull always \
|
|
-p $LLAMA_STACK_PORT:$LLAMA_STACK_PORT \
|
|
-v ~/.llama:/root/.llama \
|
|
-v ./llama_stack/templates/tgi/run-with-safety.yaml:/root/my-run.yaml \
|
|
llamastack/distribution-tgi \
|
|
--config /root/my-run.yaml \
|
|
--port $LLAMA_STACK_PORT \
|
|
--env INFERENCE_MODEL=$INFERENCE_MODEL \
|
|
--env TGI_URL=http://host.docker.internal:$INFERENCE_PORT \
|
|
--env SAFETY_MODEL=$SAFETY_MODEL \
|
|
--env TGI_SAFETY_URL=http://host.docker.internal:$SAFETY_PORT
|
|
```
|
|
|
|
### Via Conda
|
|
|
|
Make sure you have done `uv pip install llama-stack` and have the Llama Stack CLI available.
|
|
|
|
```bash
|
|
llama stack build --template tgi --image-type conda
|
|
llama stack run ./run.yaml
|
|
--port $LLAMA_STACK_PORT \
|
|
--env INFERENCE_MODEL=$INFERENCE_MODEL \
|
|
--env TGI_URL=http://127.0.0.1:$INFERENCE_PORT
|
|
```
|
|
|
|
If you are using Llama Stack Safety / Shield APIs, use:
|
|
|
|
```bash
|
|
llama stack run ./run-with-safety.yaml \
|
|
--port $LLAMA_STACK_PORT \
|
|
--env INFERENCE_MODEL=$INFERENCE_MODEL \
|
|
--env TGI_URL=http://127.0.0.1:$INFERENCE_PORT \
|
|
--env SAFETY_MODEL=$SAFETY_MODEL \
|
|
--env TGI_SAFETY_URL=http://127.0.0.1:$SAFETY_PORT
|
|
```
