Updating the VergeOS System

Comprehensive guide on performing on-demand and scheduled system updates in VergeOS, including zero-downtime update procedures and automatic tenant updates.

Overview

Key Points

• System updates should be performed during a maintenance window
• Updates can be performed with zero downtime when adequate resources are available
• System updates are only run from the host system (top-level parent)
• Tenant systems are automatically updated from their host system
• Updates can be scheduled or performed on-demand
• The system automatically handles workload migration during updates

This guide provides detailed instructions for performing system updates in VergeOS, whether on-demand or scheduled.

Prerequisites

• Administrative access to the VergeOS Cloud Dashboard
• Adequate system resources to allow workload migration during updates
• A maintenance window (recommended, though not required due to zero-downtime capability)

Performing On-Demand Updates

1. Check for Updates

1. Navigate to System > Updates in the Cloud Dashboard
2. Click Check For Updates in the left menu
3. Click Yes to confirm

   • The Packages section will show available updates
   • A cloud icon indicates downloadable packages
   • Version information displays current and available versions

2. Download Updates

1. Click Download in the left menu
2. Click Yes to confirm
3. Wait for the download to complete

3. Install Updates

1. Click Install in the left menu
2. Click Yes to confirm
3. Wait for installation to complete

   • Status will show "Idle - Reboot Required" when ready
   • The Reboot option will become enabled

Updates that don't include VergeOS package changes won't require full node reboots, but still need the Reboot option to apply changes.

4. Apply Updates

1. Click Reboot in the left menu
2. Click Yes to confirm

   • The system will process one node at a time:

     • Node enters maintenance mode
     • Workloads migrate to other nodes
     • Application restarts/node reboots
     • Node exits maintenance mode
   • Progress shows in the Status field
   • Nodes Updated status tracks completion

Use Cancel Reboot to halt automatic reboots if needed (e.g., for workload rebalancing)

Scheduling Updates

1. Create Update Task

1. Navigate to System > Updates > Tasks
2. Click New in the left menu

2. Configure Schedule

1. Choose scheduling option:

   • One-time: Keep default "Does Not Repeat"
   • Recurring: Select frequency (weekly, bi-weekly, monthly)
2. Set Start Date and time
3. For recurring tasks, optionally set end date

3. Configure Task Details

1. Enter required Name
2. Add optional Description
3. Select Task Type:

   • Choose "Download, Install, and Reboot" for complete update
4. Optional: Enable Delete After Running
5. Click Submit to save

Best Practices

• Schedule updates during low-usage periods and during maintenance windows
• Ensure adequate system resources for workload migration
• Monitor system during update process
• Keep regular backups before major updates
• Review available updates before applying

Troubleshooting

Common Issues
