- Install Chroma CLI and run the server using
chroma run - Sign up for Chroma Cloud.
- Deploy your own Chroma instance in Docker.

Additional
If you are running both SamaFlow and Chroma on Docker, there are additional steps involved.
- Spin up Chroma docker first
docker compose up -d --build
- Open
docker-compose.ymlin SamaFlow
cd SamaFlow && cd docker
- Modify the file to:
version: '3.1'
services:
samaflow:
image: flowiseai/samaflow
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:
- ~/.samaflow:/root/.samaflow
networks:
- flowise_net
command: /bin/sh -c "sleep 3; samaflow start"
networks:
flowise_net:
name: chroma_net
external: true
- Spin up SamaFlow docker image
docker compose up -d
- 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
