3. npm: In the terminal run 1) 'cd frontend' 2) 'npm install' 3) 'cd ..'

Running Balancer for development

Start the Postgres, Django REST, and React services by starting Docker Desktop and running docker compose up --build

Postgres

• Download a sample of papers to upload from https://balancertestsite.com
• The email and password of pgAdmin are specified in balancer-main/docker-compose.yml
• The first time you use pgAdmin after building the Docker containers you will need to register the server.
  • The Host name/address is the Postgres server service name in the Docker Compose file
  • The Username and Password are the Postgres server environment variables in the Docker Compose file
• You can use the below code snippet to query the database from a Jupyter notebook:

from sqlalchemy import create_engine
import pandas as pd

engine = create_engine("postgresql+psycopg2://balancer:balancer@localhost:5433/balancer_dev")

query = "SELECT * FROM api_embeddings;"

df = pd.read_sql(query, engine)

Django REST

• The email and password are set in server/api/management/commands/createsu.py

Local Kubernetes Deployment

Prereqs

• Fill the configmap with the env vars
• Install Devbox
• Run the following script with admin privileges:

HOSTNAME="balancertestsite.com"
LOCAL_IP="127.0.0.1"

# Check if the correct line already exists
if grep -q "^$LOCAL_IP[[:space:]]\+$HOSTNAME" /etc/hosts; then
  echo "Entry for $HOSTNAME with IP $LOCAL_IP already exists in /etc/hosts"
else
  echo "Updating /etc/hosts for $HOSTNAME"
  sudo sed -i "/[[:space:]]$HOSTNAME/d" /etc/hosts
  echo "$LOCAL_IP      $HOSTNAME" | sudo tee -a /etc/hosts
fi

Steps to reproduce

Inside root dir of balancer

devbox shell
devbox create:cluster
devbox run deploy:balancer

The website should be available in https://balancertestsite.com:30219/
