Lantern DB

Installation

Lantern is a Postgres extension that provides vector search inside Postgres. It is available as a Docker image, a Homebrew package, a binary, or from source.

Run with Docker

For convenience, we provide the Lantern Suite Docker image, which includes both Lantern and Lantern Extras. This enables both vector search and vector generation inside Postgres.

bash
Copy
docker run -p 5432:5432 --name lantern-demo -e 'POSTGRES_PASSWORD=postgres' -d lanterndata/lantern-suite:pg15-latest

Alternatively, to install only Lantern for vector search, we provide the Lantern Docker image.

bash
Copy
docker run -p 5432:5432 --name lantern-demo -e 'POSTGRES_PASSWORD=postgres' -d lanterndata/lantern:pg15-latest

Note: The image is based on the official Postgres docker image. Please refer to the Postgres image documentation for a full list of supported features and flags.
