Project description
Run FastFlow server
FastFlows is a FastAPI server & command line tool to comunicate with Prefect 2.0 as a Workflow manager to deploy, run, track flows and more.
To start work with FastFlows you should define at least 2 environment variables:
# Prefect API Server address
PREFECT_URI=http://localhost:4200
# Path to folder with flows
FLOWS_HOME=flows
If you want to define variables with env prefix, for example, like 'LOCAL_PREFECT_URI' or 'DEV_PREFECT_URI' you can use environment variable 'ENV_NAME'
If Fastflow will see 'ENV_NAME' variable in environment - it will search for variables with prefix defined in this ENV_NAME, for example:
if ENV_NAME = 'LOCAL'
Fastflows will read variables like LOCAL_PREFECT_URI and LOCAL_FLOWS_HOME,
if ENV_NAME = 'dev', then fastflow will expect variables like 'dev_PREFECT_URI' and 'dev_FLOWS_HOME'
Build FastFlows
To build stand alone image:
docker build . -f docker/Dockerfile -t fastflows
Run Prefect witn DB in Docker-Compose
docker-compose -f ./docker/docker-compose.yml up --build
To enter UI:
# if you will try to use 0.0.0.0 you will not see any data because of CORS issues
http://localhost:4200/flows
Run cli
fastflows --help
Flows Deployment
Auto deployment
Deployment of Flows can be done by FastFlows automatically: if there is a new flow or changes in FLOWS_HOME directory - FastFlow create new deployment. To disable auto deployment set env variable to 0
FASTFLOWS_AUTO_DEPLOYMENT = 0
