docker network create erpnext-network

• Create Shared Volume

docker volume create erpnext-shared-sites

On each server, run the appropriate compose file:

• Database Server:

docker compose -f db-compose.yml --env-file .env up -d

• Application Server 1:

docker compose -f erpnext1-compose.yml --env-file .env up -d

• Application Server 2:

docker compose -f erpnext2-compose.yml --env-file .env up -d

*Application Server 3:

docker compose -f erpnext3-compose.yml --env-file .env up -d

• Load Balancer Server:

docker compose -f lb-compose.yml --env-file .env up -d

Initialize ERPNext

After all services are running, initialize on one instance:

Connect to one app instance

docker exec -it erpnext-app-1

Set Config common_site_config.json

{
 "db_host": "erpnext-db",
 "db_port": 3306,
 "redis_cache": "redis://redis-cache:6379",
 "redis_queue": "redis://redis-queue:6379",
 "redis_socketio": "redis://redis-queue:6379",
 "socketio_port": 9000
}

Create site

bench new-site your-site-name --db-host=${DB_HOST} --db-port=${DB_PORT} --db-root-password=${DB_PASSWORD} --admin-password=admin_password_here

Install ERPNext

bench --site your-site-name install-app erpnext

Verify Connectivity

Check if all components can communicate:

From any app server, test database connection

docker exec erpnext-app-1 ping erpnext-db

Test Redis connection

docker exec erpnext-app-1 redis-cli -h redis-cache -p 6379 ping

Test load balancer

curl http://load-balancer-ip
