Milvus Operator

ATTENTIONS: THE MAIN BRANCH MAY BE IN AN UNSTABLE OR EVEN BROKEN STATE DURING DEVELOPMENT.

Overview

Milvus is a cloud-native, open-source vector database built to manage embedding vectors generated by machine learning models and neural networks. It extends the capabilities of best-in-class approximate nearest neighbor (ANN) search libraries (e.g. Faiss, NMSLIB, Annoy) and features on-demand scalability, and high availability.

The Milvus Operator provides an easy and solid solution to deploy and manage a full Milvus service stack including both the milvus components and its relevant dependencies such as etcd, pulsar and minio to the target Kubernetes clusters in a scalable and high-available way. The Milvus Operator defines a Milvus custom resources on top of Kubernetes Custom Resources. The Kubernetes API can then be used in a declarative way to manage Milvus deployment stack and ensure its scalability and high-availability operation.

Getting started

Deploy milvus operator

Install or upgrade to latest version with helm:

helm repo add milvus-operator https://zilliztech.github.io/milvus-operator/
helm repo update milvus-operator
helm -n milvus-operator upgrade --install --create-namespace milvus-operator milvus-operator/milvus-operator

Or with kubectl & raw manifests:

kubectl apply -f https://raw.githubusercontent.com/zilliztech/milvus-operator/v0.9.8/deploy/manifests/deployment.yaml

For more infomation Check Installation Instructions

Create milvus demo instance

kubectl apply -f https://raw.githubusercontent.com/zilliztech/milvus-operator/main/config/samples/demo.yaml

Note: The demo instance starts a standalone milvus & its dependencies with the least resources requests. It is not suitable for production environment. For more deployment examples please check https://github.com/zilliztech/milvus-operator/blob/main/config/samples
