Copy and adapt these examples for your projects. These patterns work for both humans and agents - when Ona Agent sees these tasks available, it can use them as part of its run loop.

​
Database provisioning

Start PostgreSQL and seed it with development data: 
services:
  postgresql:
    name: PostgreSQL
    description: Development database
    triggeredBy:
      - postDevcontainerStart
    commands:
      start: docker run -d --name postgres -e POSTGRES_PASSWORD=postgres -p 5432:5432 postgres:15
      ready: docker exec postgres pg_isready -U postgres

tasks:
  seed:
    name: Seed database
    triggeredBy:
      - manual
    command: ./scripts/seed-dev-db.sh

​
Containerized services with runsOn

Run services in isolated containers using runsOn.docker: 
services:
  redis:
    name: Redis
    description: In-memory cache
    triggeredBy:
      - postDevcontainerStart
    runsOn:
      docker:
        image: redis:7-alpine
        environment:
          - REDIS_MAXMEMORY=256mb
          - REDIS_MAXMEMORY_POLICY=allkeys-lru
    commands:
      start: redis-server
      ready: redis-cli ping | grep -q PONG
      stop: redis-cli shutdown

  elasticsearch:
    name: Elasticsearch
    description: Search engine
    triggeredBy:
      - manual
    runsOn:
      docker:
        image: elasticsearch:8.11.0
        environment:
          - discovery.type=single-node
          - xpack.security.enabled=false
          - ES_JAVA_OPTS=-Xms512m -Xmx512m
    commands:
      start: /usr/local/bin/docker-entrypoint.sh
      ready: curl -sf http://localhost:9200/_cluster/health

​
Prebuild optimization

Speed up environment starts by running tasks during prebuild: 
tasks:
  install-deps:
    name: Install dependencies
    description: Install and cache all dependencies
    triggeredBy:
      - prebuild
    command: |
      npm ci
      go mod download
      pip install -r requirements.txt

  build-assets:
    name: Build static assets
    description: Compile CSS and bundle JavaScript
    triggeredBy:
      - prebuild
    dependsOn:
      - install-deps
    command: npm run build:assets

  warm-cache:
    name: Warm build cache
    description: Pre-compile common modules
    triggeredBy:
      - prebuild
    dependsOn:
      - install-deps
    command: go build -v ./...
Tasks with the prebuild trigger run during prebuild execution. Organization and project secrets are available, but user secrets are not.

​
Build and test pipeline

Chain tasks with dependencies: 
tasks:
  build:
    name: Build
    command: yarn && yarn build

  test:
    name: Run tests
    dependsOn:
      - build
    command: yarn test

  setup:
    name: Full setup
    dependsOn:
      - build
      - test
    triggeredBy:
      - postDevcontainerStart
    command: echo "Ready to develop"
Agents can run test knowing it will build first.

​
Cloud authentication

Authenticate with AWS using Ona’s identity provider: 
tasks:
  aws-auth:
    name: AWS Auth
    triggeredBy:
      - postEnvironmentStart
    command: gitpod idp login aws --role arn:aws:iam::123456789:role/dev-role

​
Preview server

Serve your application for testing: 
services:
  preview:
    name: Preview server
    triggeredBy:
      - postDevcontainerStart
    commands:
      start: |
        npm install
        npm run build
        npx serve -p 3000 ./build
      ready: curl -sf http://localhost:3000 > /dev/null
Agents can share this preview URL when demonstrating changes.

​
Jupyter notebook

services:
  jupyter:
    name: Jupyter Notebook
    triggeredBy:
      - manual
    commands:

    triggeredBy:
      - manual
    commands:
      start: yarn storybook
      ready: curl -sf http://localhost:6006 > /dev/null

​
