Instalação Langflow
Link: https://docs.langflow.org/deployment-docker
This guide will help you get LangFlow up and running using Docker and Docker Compose.
Prerequisites​
Docker
Docker Compose
Docker​
Clone repo and build Docker container​
Clone the LangFlow repository:
git clone https://github.com/langflow-ai/langflow.git
Navigate to the 
docker_example directory:
cd langflow/docker_example
Run the Docker Compose file:
docker compose up
LangFlow will now be accessible at http://localhost:7860/.
Docker Compose configuration​
The Docker Compose configuration spins up two services: 
langflow and 
postgres.
LangFlow service​
The 
langflow service uses the 
langflowai/langflow:latest Docker image and exposes port 7860. It depends on the 
postgres service.
Environment variables:
LANGFLOW_DATABASE_URL: The connection string for the PostgreSQL database.
LANGFLOW_CONFIG_DIR: The directory where LangFlow stores logs, file storage, monitor data, and secret keys.
Volumes:
langflow-data: This volume is mapped to 
/var/lib/langflow in 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:
langflow-postgres: This volume is mapped to 
/var/lib/postgresql/data in the container.
Switch to a specific LangFlow version​
If you want to use a specific version of LangFlow, you can modify the 
image field under the 
langflow service in the Docker Compose file. For example, to use version 1.0-alpha, change 
langflowai/langflow:latest to 
langflowai/langflow:1.0-alpha.
