 ### Initialize the database schema and seed data
 
-Once the database is reachable and `DATABASE_URL` is set, start the dev server and call:
+There are several ways to initialize the database depending on your environment:
 
+#### Option 1: Using the init-db.sh script (for direct server access)
+
+If you have direct access to the Kubernetes cluster, you can use the `init-db.sh` script:
+
+```bash
+./init-db.sh
+```
+
+This script will automatically detect the postgres pod and initialize the database with all required tables and seed data.
+
+#### Option 2: Using the Kubernetes job (recommended for production)
+
+To initialize the database using a Kubernetes job:
+
+```bash
+kubectl apply -f k8s/init-db-job.yaml
+```
+
+You can monitor the job status with:
+```bash
+kubectl get jobs -n lahuasca
+kubectl get pods -n lahuasca | grep init-database
+```
+
+To view the job logs:
+```bash
+kubectl logs -n lahuasca -l job-name=init-database
+```
+
+Once the job completes successfully, you can remove it:
+```bash
+kubectl delete job init-database -n lahuasca
+```
+
+#### Option 3: Using the API endpoint (development only)
+
+Note: This method only works in development mode and is disabled in production.
+
+Start the dev server and call:
 ```bash
 curl -X POST http://localhost:3000/api/db/init
 ```
 
 To reset everything (drops and recreates tables with seed data):
-
 ```bash
 curl -X POST "http://localhost:3000/api/db/init?reset=true"
 ```
