Build your own Distribution
This guide will walk you through the steps to get started with building a Llama Stack distribution from scratch with your choice of API providers.
Llama Stack Build
In order to build your own distribution, we recommend you clone the llama-stack repository.
git clone git@github.com:meta-llama/llama-stack.git
cd llama-stack
pip install -e .
llama stack build -h
We will start build our distribution (in the form of a Conda environment, or Container image). In this step, we will specify:
name: the name for our distribution (e.g.my-stack)image_type: our build image type (conda | container)distribution_spec: our distribution specs for specifying API providersdescription: a short description of the configurations for the distributionproviders: specifies the underlying implementation for serving each API endpointimage_type:conda|containerto specify whether to build the distribution in the form of Container image or Conda environment.
After this step is complete, a file named <name>-build.yaml and template file <name>-run.yaml will be generated and saved at the output file path specified at the end of the command.
::::{tab-set} :::{tab-item} Building from Scratch
- For a new user, we could start off with running
llama stack buildwhich will allow you to a interactively enter wizard where you will be prompted to enter build configurations.
llama stack build
> Enter a name for your Llama Stack (e.g. my-local-stack): my-stack
> Enter the image type you want your Llama Stack to be built as (container or conda): conda
Llama Stack is composed of several APIs working together. Let's select
the provider types (implementations) you want to use for these APIs.
Tip: use <TAB> to see options for the providers.
> Enter provider for API inference: inline::meta-reference
> Enter provider for API safety: inline::llama-guard
> Enter provider for API agents: inline::meta-reference
> Enter provider for API memory: inline::faiss
> Enter provider for API datasetio: inline::meta-reference
> Enter provider for API scoring: inline::meta-reference
> Enter provider for API eval: inline::meta-reference
> Enter provider for API telemetry: inline::meta-reference
> (Optional) Enter a short description for your Llama Stack:
You can now edit ~/.llama/distributions/llamastack-my-local-stack/my-local-stack-run.yaml and run `llama stack run ~/.llama/distributions/llamastack-my-local-stack/my-local-stack-run.yaml`

:::{tab-item} Building from a template
- To build from alternative API providers, we provide distribution templates for users to get started building a distribution backed by different providers.
The following command will allow you to see the available templates and their corresponding providers.
llama stack build --list-templates

You may then pick a template to build your distribution with providers fitted to your liking.
For example, to build a distribution with TGI as the inference provider, you can run:
llama stack build --template tgi
$ llama stack build --template tgi
...
You can now edit ~/.llama/distributions/llamastack-tgi/tgi-run.yaml and run `llama stack run ~/.llama/distributions/llamastack-tgi/tgi-run.yaml`
:::
:::{tab-item} Building from a pre-existing build config file
-
In addition to templates, you may customize the build to your liking through editing config files and build from config files with the following command.
-
The config file will be of contents like the ones in
llama_stack/templates/*build.yaml.
$ cat llama_stack/templates/ollama/build.yaml
name: ollama
distribution_spec:
description: Like local, but use ollama for running LLM inference
providers:
inference: remote::ollama
memory: inline::faiss
safety: inline::llama-guard
agents: inline::meta-reference
telemetry: inline::meta-reference
image_type: conda
llama stack build --config llama_stack/templates/ollama/build.yaml
:::
:::{tab-item} Building Container
Tip
Podman is supported as an alternative to Docker. Set
CONTAINER_BINARYtopodmanin your environment to use Podman.
To build a container image, you may start off from a template and use the --image-type container flag to specify container as the build image type.
llama stack build --template ollama --image-type container
$ llama stack build --template ollama --image-type container
...
Containerfile created successfully in /tmp/tmp.viA3a3Rdsg/ContainerfileFROM python:3.10-slim
...
You can now edit ~/meta-llama/llama-stack/tmp/configs/ollama-run.yaml and run `llama stack run ~/meta-llama/llama-stack/tmp/configs/ollama-run.yaml`
After this step is successful, you should be able to find the built container image and test it with llama stack run <path/to/run.yaml>.

Running your Stack server
Now, let's start the Llama Stack Distribution Server. You will need the YAML configuration file which was written out at the end by the llama stack build step.
llama stack run ~/.llama/distributions/llamastack-my-local-stack/my-local-stack-run.yaml
$ llama stack run ~/.llama/distributions/llamastack-my-local-stack/my-local-stack-run.yaml
