# cnpgvecto.rs
|
|
Container images for [cloudnative-pg](https://cloudnative-pg.io/) with the [pgvecto.rs](https://github.com/tensorchord/pgvecto.rs) extension installed.
|
|
|
|
|
|
> [!IMPORTANT]
|
|
> If you are using this image on an existing database, the postgres configuration needs to be
|
|
> altered to enable the extension. You can do this by setting shared_preload_libraries in your Cluster spec:
|
|
> ```yaml
|
|
> apiVersion: postgresql.cnpg.io/v1
|
|
> kind: Cluster
|
|
> spec:
|
|
> (...)
|
|
> postgresql:
|
|
> shared_preload_libraries:
|
|
> - "vectors.so"
|
|
> ```
|
|
|
|
> [!IMPORTANT]
|
|
> The `pgvecto.rs` extension is not enabled by default. You need to enable it and set the search path when initializing the database. You can configure it in your Cluster spec:
|
|
> ```yaml
|
|
> apiVersion: postgresql.cnpg.io/v1
|
|
> kind: Cluster
|
|
> spec:
|
|
> (...)
|
|
> bootstrap:
|
|
> initdb:
|
|
> postInitSQL:
|
|
> - ALTER SYSTEM SET search_path TO "$user", public, vectors;
|
|
> - CREATE EXTENSION IF NOT EXISTS "vectors";

## Building
|
|
|
|
To build the Dockerfile locally, you need to pass the `CNPG_TAG` and `PGVECTORS_TAG` args. For example:
|
|
`docker build . --build-arg="CNPG_TAG=16.3" --build-arg="PGVECTORS_TAG=v0.2.1"` |
