Prerequisites

• Go version 1.21.0
• docker-compose (you may need to update docker-compose.yml for intel based computer)

Steps

1. Pull the source code
2. Start the databases: docker compose up -d
3. Create a Postgre test database. Use any database client to create a database name test and grant permission for the default user postgres on it.

CREATE DATABASE test;
GRANT ALL PRIVILEGES ON DATABASE test TO postgres;

1. Start the API server, it should automatically provision the tables. From the repo’s root directory, type

go run api-server/app.go

1. Start other workers to complete the full system, open other terminal tabs for these commands

go run worker-due-job-checker/app.go

go run worker-job-fixer/app.go

go run data-feed/app.go

Monitoring

I haven’t handled the Grafana database migration yet, so you need to head to the Grafana dashboard at http://localhost:3000 according to the docker-compose file Grafana port.

1. Setup Prometheus as the data source
2. Play around with the metrics sent from the scheduling system
