Vector DBs

Local deployment of different vector databases using Minikube.

Minikube: Getting Started

To install minikube check the docs

The configuration I'm using is the following:

• driver=podman
• rootless true
• container-runtime=containerd docs

Commands

Get the status

minikube status

Start Cluster

minikube start

Stop Cluster

minikube stop

Get info about the nodes in your cluster

kubectl get nodes -o wide

docs

minikube tunnel

Env Variables

Create a .env file to store your variables. You will need one per database, run the following to create it automatically

Generate pgvector .env file

cat > pgvector/.env << EOF
# PgVector
POSTGRES_DB=dbname
POSTGRES_USER=postgres
POSTGRES_PASSWORD=password
EOF

Deployment scripts will create a secret per db referenced by the deployment.yml file

Deployments

---

Important!!

Before you run any deployment script, check your .env files, if you want to use a different one just pass it to the script, by default it will use .env (Remember that each db has its own env file)

bash deploy_dbs.sh --env ".env_prod"

or

bash deploy_dbs.sh -e ".env_prod"

---

Deploy PgVector

To deploy pgvector, use --pgvector flag

bash deploy_dbs.sh --pgvector

Deploy Multiple DBs

db_flag: --pgvector

bash deploy_dbs.sh --db_flag1 --db_flag2

Test DB access

To get the external ip

kubectl get services

if you don't see it, run:

minikube tunnel

PgVector

Check if the db is accepting connections

pg_isready -d ${POSTGRES_DB} -h ${EXTERNAL_IP} -p 5432 -U ${POSTGRES_USER}

Open a connection docs

psql -d ${POSTGRES_DB} -h ${EXTERNAL_IP} -p 5432 -U ${POSTGRES_USER}

Delete Resources

PgVector

kubectl delete service pgvector && \
kubectl delete deployment pgvector  && \
kubectl delete pv pgvector-pv  && \
kubectl delete pvc pgvector-pvc  && \
kubectl delete secret pgvector-secrets
