Deployment Skill

Deploy to App Platform using GitHub Actions and the app_action workflow.

Philosophy: PUSH Mode Deployment

This skill focuses on PUSH mode — where you define infrastructure as code and GitHub Actions drives deployment.

PULL MODE (Console-driven) — NOT covered by this skill
• Go to DigitalOcean Console → Create App → Point to GitHub
• App Platform auto-generates app spec
• Good for: Quick starts, manual one-offs

PUSH MODE (CLI/Actions-driven) — THIS SKILL
• Define app spec in repo (.do/app.yaml)
• Use GitHub Actions + app_action to deploy
• Good for: CI/CD, automation, GitOps, multi-environment

Tip: For complex projects, consider the planner skill for staged approaches. See root SKILL.md for all skills.

Quick Decision

Using GitHub Actions? (RECOMMENDED)
├── YES → Use digitalocean/app_action/deploy@v2
│         • Handles spec updates AND code deployments
│         • Manages app creation if doesn't exist
│         • Supports PR previews
│
└── NO (Manual/Scripting)
    ├── Spec changed? → doctl apps update --spec
    └── Code only? → doctl apps create-deployment

Command	Purpose	When to Use
doctl apps create --spec	Create new app	First deployment only
doctl apps update --spec	Update app spec	Config changes
doctl apps create-deployment	Trigger rebuild	Code changes only
app_action v2	Both spec + rebuild	Recommended: Handles everything

---

Quick Start: Environment Setup

# 1. Create DigitalOcean projects
doctl projects create --name "myapp-staging" --environment "Staging"
doctl projects create --name "myapp-production" --environment "Production"

# 2. Create GitHub environments
gh api --method PUT repos/:owner/:repo/environments/staging
gh api --method PUT repos/:owner/:repo/environments/production

# 3. Set secrets per environment (user fills in values)
gh secret set DIGITALOCEAN_ACCESS_TOKEN --env staging
gh secret set DIGITALOCEAN_ACCESS_TOKEN --env production
gh variable set DO_PROJECT_ID --env staging --body "PROJECT_ID"
gh variable set DO_PROJECT_ID --env production --body "PROJECT_ID"

Full setup guide: See initial-setup.md

Quick Start: Basic Workflow

# .github/workflows/deploy.yml
name: Deploy
on:
  push:
    branches: [main]
jobs:
  deploy:
    runs-on: ubuntu-latest
    environment: staging
    steps:
      - uses: actions/checkout@v4
      - uses: digitalocean/app_action/deploy@v2
        env:
          DATABASE_URL: ${{ secrets.DATABASE_URL }}
        with:
          token: ${{ secrets.DIGITALOCEAN_ACCESS_TOKEN }}
          project_id: ${{ vars.DO_PROJECT_ID }}

All workflow templates: See workflow-templates.md

---

Workflow Selection

Scenario	Workflow	Reference
Simple single-environment	Minimum viable	workflow-templates.md
Staging + production	Environment-based	workflow-templates.md
Production needs approval	Protected environment	workflow-templates.md
Test PRs before merge	PR previews	workflow-templates.md
Multiple envs, one workflow	Unified workflow	workflow-templates.md
Need to revert	Rollback	workflow-templates.md

---

Quick Start: Debug Container

For complex apps with multiple integrations, deploy a debug container first:

# Add to .do/app.yaml temporarily
workers:
  - name: debug
    image:
      registry_type: GHCR
      registry: ghcr.io
      repository: bikramkgupta/do-app-debug-container-python
      tag: latest
    instance_size_slug: apps-s-1vcpu-2gb
    envs:
      - key: DATABASE_URL
        scope: RUN_TIME
        value: ${db.DATABASE_URL}

# Connect and verify
doctl apps console $APP_ID debug
./diagnose.sh

Full guide: See debug-container-deployment.md

---

Quick Command Reference

Task	Command
Validate spec	doctl apps spec validate .do/app.yaml
Create app	doctl apps create --spec .do/app.yaml --project-id $PROJECT_ID
Update app	doctl apps update $APP_ID --spec .do/app.yaml
Redeploy	doctl apps create-deployment $APP_ID
View logs	doctl apps logs $APP_ID --type run
Set secret	gh secret set NAME --env staging
List secrets	gh secret list --env staging

Full reference: See command-reference.md

Reference Files

File	Content
initial-setup.md	Projects, environments, secrets, app spec setup
workflow-templates.md	All GitHub Actions workflow YAML templates
debug-container-deployment.md	Debug container for infrastructure verification
command-reference.md	Complete doctl and gh CLI commands

---

Quick Troubleshooting

Issue	Symptom	Fix
App spec not found	Error: spec file not found	Ensure .do/app.yaml exists
Invalid token	401 Unauthorized	Check DIGITALOCEAN_ACCESS_TOKEN secret
Project not found	project_id is invalid	Verify DO_PROJECT_ID variable
Build fails	BuildJobFailed	Check build logs: doctl apps logs $APP_ID --type build
Env vars literal	Values show ${...}	Check bindable variable names match

---

Opinionated Defaults

Decision	Default	Rationale
CI Platform	GitHub Actions	Best DO integration via app_action
Deploy Action	app_action/deploy@v2	Handles spec + deploy in one step
Secrets	GitHub Secrets per environment	Secure, AI never sees values
deploy_on_push	false in app spec	Let GitHub Actions control deploys
App spec location	.do/app.yaml	Conventional, matches DO button

---

Integration with Other Skills

• ← designer: Creates .do/app.yaml that deployment consumes
• ← postgres: Handles database setup, stores DATABASE_URL in GitHub Secrets
• → troubleshooting: Debug deployment failures
• ← devcontainers: Ensure local dev matches production

---

Production Checklist

• DO Projects created with environment tags
• GitHub environments created (staging, production)
• DIGITALOCEAN_ACCESS_TOKEN secret set per environment
• DO_PROJECT_ID variable set per environment
• .do/app.yaml with deploy_on_push: false
• .github/workflows/deploy.yml created
• Production protection rules enabled
• Staging deployment tested
• Production deployment tested
