Additional

If you are running both Flowise and Chroma on Docker, there are additional steps involved.

  1. Spin up Chroma docker first

docker-compose up -d --build

  1. Open docker-compose.yml in Flowise

cd Flowise && cd docker

  1. Modify the file to:

version: '3.1'

services:
    flowise:
        image: flowiseai/flowise
        restart: always
        environment:
            - PORT=${PORT}
            - FLOWISE_USERNAME=${FLOWISE_USERNAME}
            - FLOWISE_PASSWORD=${FLOWISE_PASSWORD}
            - DEBUG=${DEBUG}
            - DATABASE_PATH=${DATABASE_PATH}
            - APIKEY_PATH=${APIKEY_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

  1. Spin up Flowise docker image

docker-compose up -d

  1. On the Chroma URL, for Windows and MacOS Operating Systems specify http://host.docker.internal:8000. For Linux based systems the default docker gateway should be used since host.docker.internal is not available: http://172.17.0.1:8000
