### Adicional

Si estás ejecutando tanto Flowise como Chroma en Docker, hay pasos adicionales involucrados.

1. Inicia primero el docker de Chroma

```bash
docker compose up -d --build
```

2. Abre `docker-compose.yml` en Flowise

```bash
cd Flowise && cd docker
```

3. Modifica el archivo a:

```sh
version: '3.1'

services:
    flowise:
        image: flowiseai/flowise
        restart: always
        environment:
            - PORT=${PORT}
            - DEBUG=${DEBUG}
            - DATABASE_PATH=${DATABASE_PATH}
            - SECRETKEY_PATH=${SECRETKEY_PATH}
            - FLOWISE_SECRETKEY_OVERWRITE=${FLOWISE_SECRETKEY_OVERWRITE}
            - LOG_PATH=${LOG_PATH}
            - LOG_LEVEL=${LOG_LEVEL}
            - EXECUTION_MODE=${EXECUTION_MODE}
        ports:
            - '${PORT}:${PORT}'
        volumes:
            - ~/.flowise:/root/.flowise
        networks:
            - flowise_net
        command: /bin/sh -c "sleep 3; flowise start"
networks:
    flowise_net:
        name: chroma_net
        external: true
```

4. Inicia la imagen docker de Flowise

```bash
docker compose up -d
```

5. En la URL de Chroma, para sistemas operativos Windows y MacOS especifica [http://host.docker.internal:8000](http://host.docker.internal:8000/). Para sistemas basados en Linux, se debe usar el gateway por defecto de docker ya que host.docker.internal no está disponible: [http://172.17.0.1:8000](http://172.17.0.1:8000/)
