Get Started

go build

Set db password

export POSTGRES_PASSWORD=sprinkler

Start the docker container

docker compose up -d

Start web service

docker compose exec ws bash

Initilize the database with some sample data

go run . database initialize --with-sample --config .sprinkler.yaml

Log into database to check whether the tables are created and populated with some sample data.

docker compose exec db psql -h db -U postgres

Start control service on a new tab, to later post a Sprinkler json workflow

go run . service control --config .sprinkler.yaml 

Put to http://localhost:8080/v1/workflow a Sprinkler workflow, example payload from ExampleWorkflow.scala

{
    "name": "test-workflow",
    "artifact": "s3://sprinkler-salesforce-bucket/jars/test/spade-example.jar",
    "command":  "[\"java\", \"-cp\", \"spade-example.jar\", \"com.salesforce.mce.spade.examples.ExampleWorkflow\", \"generate\", \"--compact\"]",
    "every": "60.minute",
    "nextRuntime": "2024-08-22T21:00:00Z",
    "backfill": false,
    "owner": "arn:aws:sns:us-east-2:444455556666:MyTopic",
    "isActive": true
}

Start fake orchard service

go run . service orchard

This will start fake orchard service listening on port 8082 based on .sprinkler.yaml scheduler orchardAddress.

Open another tab to run the scheduler.

go run . service scheduler --config .sprinkler.yaml

The scheduler should start scheduling the sample workflows.
