Minikube (mini-langstream)
To create a LangStream cluster locally, it's recommended to use minikube - setting 4 CPUs is highly recommended.
mini-langstream comes in help for installing and managing your local cluster.mini-langstream requires the following commands to be already installed:
- Docker
- Minikube
- Helm
- Kubectl
- LangStream CLI
If you install mini-langstream using Brew, all the dependencies are automatically installed.
MacOS:
brew install LangStream/langstream/mini-langstream
Unix:
curl -Ls "https://raw.githubusercontent.com/LangStream/langstream/main/mini-langstream/get-mini-langstream.sh" | bash
mini-langstream will do all the setup for you, in particular:
- start
minikubein a dedicated context - deploy LangStream components using
helm - run a stateful Kafka broker as docker container
- run a stateful s3-compatible storage (MinIO) as docker container
- forward the control plane and API Gateways ports locally
- create a dedicated LangStream CLI profile to interact with the cluster
- wrap all the common k8s tools to inspect the cluster (
mini-langstream kubectl,mini-langstream helm,mini-langstream k9s)
- 1.Start or ensure the cluster is running:
mini-langstream start
- 2.Try to use the CLI:
mini-langstream cli apps list
- 3.Deploy an application:
export OPENAI_API_KEY=<your-openai-api-key>
mini-langstream cli apps deploy my-app -app https://github.com/LangStream/langstream/tree/main/examples/applications/openai-completions -s https://github.com/LangStream/langstream/blob/main/examples/secrets/secrets.yaml
To delete all the storage and stop the cluster:
mini-langstream delete
Here are a few ways to get started building LangStream applications:
