Deployment with Docker Compose

This method deploys all HCW@Home services in Docker containers. It is the recommended approach for development, testing, and cloud environments.

Prerequisites

Docker Engine 20+ and Docker Compose v2
Minimum 2 GB RAM
A domain name (production) or localhost (development)

Quick Start

1. Clone the repository

wget https://raw.githubusercontent.com/HCW-home/hcw/refs/heads/master/docker-compose.yml

2. Configure the environment

Copy the configuration file:

TAG=0.10.0 docker compose pull

Then adjust the environment: blocks of docker-compose.yml to match your setup. The api, celery, scheduler and migrate services must all share the same database, Redis and secret key settings. See Environment Variables for the full reference.

Security

Never use the default values for DJANGOSECRET_KEY in production. Generate a key with: echo -n "your secret phrase" | sha256sum

3. Start the services

docker compose up -d

On first launch, the migrate service automatically applies database migrations.

4. Create a tenant

HCW@Home uses multi-tenancy with PostgreSQL schema isolation. Each tenant has its own data, users, and configuration. Tenants are created via the Django shell.

docker compose exec api python3 manage.py create_tenant

schema name: localhost
name: localhost
domain: 127.0.0.1

docker compose exec api python3 manage.py tenant_command createsuperuser -s localhost

Multiple tenants

Repeat this process for each organization. Each tenant is fully isolated: separate users, consultations, configuration, and branding.

5. Load test data (optional)

docker compose exec api python manage.py loaddata initial/TestData.json

This creates test users (password: Test1234). See the README for the full list.
