Platform Updates

eb status            # Check current platform
eb platform list     # List available platforms
eb upgrade           # Upgrade to latest
eb platform select   # Select different platform

Restart Application Server

eb restart
eb restart <env-name>

Pending Managed Actions

aws elasticbeanstalk describe-environment-managed-actions \
  --environment-name <env-name> --output json

Managed Action History

aws elasticbeanstalk describe-environment-managed-action-history \
  --environment-name <env-name> --output json

Configure Managed Updates

eb config

When ManagedActionsEnabled is true, you must also set PreferredStartTime and UpdateLevel:

aws:elasticbeanstalk:managedactions:
  ManagedActionsEnabled: 'true'
  PreferredStartTime: 'Tue:09:00'    # Format: day:hour:minute (UTC)
aws:elasticbeanstalk:managedactions:platformupdate:
  UpdateLevel: minor                  # Values: patch | minor

• patch — patch version updates only (e.g., 2.0.7 → 2.0.8)
• minor — minor and patch updates (e.g., 2.0.8 → 2.1.0)

Platform Migration (Blue/Green)

1. Clone environment: eb clone <env> --clone_name <env>-migrated
2. Select new platform: eb platform select
3. Test: eb status && eb health && eb open
4. Swap: eb swap <env> --destination_name <env>-migrated
5. Terminate old: eb terminate <env> --force
