Deploy

Deploy to Elastic Beanstalk

Deploy application code, manage versions, rollback, and configure deployment strategies using the EB CLI.

When to Use

• Deploy code to an environment
• Rollback to a previous version
• Configure deployment strategies (rolling, immutable, etc.)
• Create application versions without deploying
• Set up CI/CD integration
• Configure .ebignore
• Configure CodeCommit as deploy source
• Test Docker app locally before deploying

When NOT to Use

• Creating new environments → use environment skill
• Checking status after deploy → use status skill
• Viewing deployment logs → use logs skill
• Changing configuration settings → use config skill

Pre-Deploy Checklist

eb status    # Verify environment is Ready
eb health    # Verify health is Green

If health is Red or environment is Updating, do NOT deploy. Fix issues first.

Quick Deploy

eb deploy

Deploy to specific environment:

eb deploy <env-name>

Deploy with Version Label

eb deploy --label "v1.2.3"
eb deploy --label "v1.2.3" --message "Release v1.2.3 - Bug fixes"

Deploy Staged Changes Only

eb deploy --staged

Deploy Existing Version

eb deploy --version <version-label>

Create Version Without Deploying

eb deploy --process

Monitor Deployment

eb events --follow

Post-Deploy Verification

eb status    # Confirm version deployed
eb health    # Confirm health is Green
eb events    # Check for warnings
eb open      # Open in browser

Look for:

• "New application version was deployed" — success
• "Environment health has transitioned from Ok to ..." — health degradation
• "Rolling back to version" — automatic rollback triggered

Rollback

# List available versions
eb appversion

# Deploy previous known-good version
eb deploy --version <previous-version>

# Verify rollback
eb status
eb health

Deployment Strategies

• AllAtOnce (Default) — Fastest, causes downtime
• Rolling — Updates in batches, maintains capacity
• RollingWithAdditionalBatch — Maintains full capacity
• Immutable — Safest, deploys to new instances
• TrafficSplitting — Canary deployments
• Blue/Green — CNAME swap (see environment skill)

Configure via eb config:

aws:elasticbeanstalk:command:
  DeploymentPolicy: Rolling
  BatchSize: '30'
  BatchSizeType: Percentage

.ebignore File

node_modules/
.venv/
__pycache__/
dist/
build/
.env
.env.local
.idea/
.vscode/
.git/

Code Source (CodeCommit Integration)

eb codesource                  # Choose between CodeCommit and local
eb codesource codecommit       # Enable CodeCommit integration
eb codesource local            # Disable CodeCommit, use local source

Note: CodeCommit integration is not available in all AWS Regions.

Local Testing (Docker)

Test Docker-based apps locally before deploying. Requires Docker installed. Linux/macOS only.

eb local run                   # Run containers locally
eb local run --port 8080       # Map to specific host port
eb local status                # Check local container status
eb local open                  # Open in browser
eb local logs                  # Show log file locations
eb local setenv KEY=value      # Set local env vars
eb local printenv              # View local env vars

CI/CD Integration

eb deploy --nohang    # Non-interactive deploy
eb status --wait      # Wait for completion
eb health             # Verify healthy

Composability

• Check status after deploy: Use status skill
• View deployment logs: Use logs skill
• Change deployment config: Use config skill
• Create new environment: Use environment skill
• Manage app versions: Use app skill
