bsantanna/cloudnative-pg-vector repository overview

⁠cloudnative-pg-vector

PostgreSQL that understands vectors.

bsantanna/cloudnative-pg-vector is the official CloudNativePG PostgreSQL 17 image with pgvector⁠ added. Embeddings, similarity search and RAG, running in the same Kubernetes-native Postgres you already trust.

⁠Run it

Point your CloudNativePG cluster at the image:

apiVersion: postgresql.cnpg.io/v1
kind: Cluster
metadata:
  name: vector-db
spec:
  instances: 3
  imageName: bsantanna/cloudnative-pg-vector:17.11
  storage:
    size: 10Gi
  bootstrap:
    initdb:
      postInitApplicationSQL:
        - CREATE EXTENSION IF NOT EXISTS vector;

kubectl apply -f vector-db.yaml

Then search by similarity:

CREATE TABLE items (id bigserial PRIMARY KEY, embedding vector(3));
INSERT INTO items (embedding) VALUES ('[1,2,3]'), ('[4,5,6]');
SELECT * FROM items ORDER BY embedding <-> '[3,1,2]' LIMIT 5;

This image is built for the CloudNativePG operator⁠. It isn't meant to run on its own with docker run.
