# Running LangFlow with Docker
This guide will help you get LangFlow up and running using Docker and Docker Compose.
## Prerequisites
- Docker
- Docker Compose
## Steps
1. Clone the LangFlow repository:
```sh
git clone https://github.com/langflow-ai/langflow.git
```
2. Navigate to the `docker_example` directory:
```sh
cd langflow/docker_example
```
3. Run the Docker Compose file:
```sh
docker compose up
```
LangFlow will now be accessible at [http://localhost:7860/](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.
## Switching 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`.
