Single generic package name for white-label compatibility. - git mv src/backend/base/hanzoflow/ -> src/backend/base/flow/ - git rm src/backend/base/langflow/ (compat shim, no longer needed) - git mv src/backend/hanzoflow/ -> src/backend/flow/ (root package) - Rename langflow_launcher.py -> launcher.py - Update all Python imports: from langflow/hanzoflow -> from flow - Update all string module references in mock targets, JSON data files - Update pyproject.toml entry points, hatch build targets, mypy/codeflash config - Update Dockerfile, Makefile, compose files, CI workflows, codecov.yml - Rename internal classes: HanzoflowApplication -> FlowApplication, etc. - Update alembic.ini database name - Keep PyPI package names (hanzoflow, langflow-base) unchanged - Keep LANGFLOW_* env var names for backwards compatibility
Running Hanzo Flow with Docker
This guide will help you get Hanzo Flow up and running using Docker and Docker Compose.
Prerequisites
- Docker
- Docker Compose
Steps
-
Clone the Hanzo Flow repository:
git clone https://github.com/hanzoai/flow.git -
Navigate to the
docker_exampledirectory:cd flow/docker_example -
Run the Docker Compose file:
docker compose up
Hanzo Flow will now be accessible at http://localhost:7860/.
Docker Compose Configuration
The Docker Compose configuration spins up two services: hanzoflow and postgres.
Hanzo Flow Service
The hanzoflow service uses the hanzoflowai/hanzoflow:latest Docker image and exposes port 7860. It depends on the postgres service.
Environment variables:
HANZOFLOW_DATABASE_URL: The connection string for the PostgreSQL database.HANZOFLOW_CONFIG_DIR: The directory where Hanzo Flow stores logs, file storage, monitor data, and secret keys.
Volumes:
hanzoflow-data: This volume is mapped to/app/hanzoflowin the container.
PostgreSQL Service
The postgres service uses the postgres:16 Docker image and exposes port 5432.
Environment variables:
POSTGRES_USER: The username for the PostgreSQL database.POSTGRES_PASSWORD: The password for the PostgreSQL database.POSTGRES_DB: The name of the PostgreSQL database.
Volumes:
hanzoflow-postgres: This volume is mapped to/var/lib/postgresql/datain the container.
Switching to a Specific Version
If you want to use a specific version of Hanzo Flow, you can modify the image field under the hanzoflow service in the Docker Compose file. For example, to use version 1.0-alpha, change hanzoflowai/hanzoflow:latest to hanzoflowai/hanzoflow:1.0-alpha.
