Helm Charts

The system uses Helm charts for Kubernetes deployment.

Chart Structure

helm/tradingbots/
├── Chart.yaml              # Chart metadata
├── values.yaml             # Bot configurations
└── templates/
    ├── cronjob.yaml        # Generates CronJobs for each bot
    ├── postgresql-secret.yaml
    ├── postgresql-deployment.yaml
    └── postgresql-service.yaml

Configuration

Edit helm/tradingbots/values.yaml to configure:

  • Bot schedules (cron format)
  • Resource limits
  • Database settings
  • Image repository and tags

Adding a Bot

Add to values.yaml:

bots:
  - name: mynewbot
    schedule: "*/5 * * * 1-5"  # Every 5 minutes, Mon-Fri

The CronJob is automatically generated from the template.

Schedule Format

Standard cron syntax:

  • */5 * * * 1-5 - Every 5 minutes, Monday-Friday
  • 0 17 * * 1-5 - Daily at 5:00 PM, Monday-Friday
  • 0 17 * * 2 - Weekly on Tuesday at 5:00 PM

Deployment

helm upgrade --install tradingbots \
      ./helm/tradingbots \
      --create-namespace \
      --namespace tradingbots-2025
