# 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 `/app/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`.
