Changelog

Zero-Downtime Deployment & Faster Container Restarts

Instant restarts, no build delays — app builds are now baked into the Docker image so containers spin up in seconds instead of minutes.

• Zero-Downtime Deploy: New script/deploy.sh for all the apps — builds the new image while the current container keeps serving traffic, then hot-swaps to the new container with no manual downtime
• Health-Gated Rollout: The deploy script waits for Docker's health check to pass (up to 120s) before declaring success, ensuring the new container is fully ready before traffic is handed off

• Build at Image Time: npm run build now runs during docker build (image layer) instead of at container startup — containers start in seconds rather than waiting for a full compile
• Health Checks Added: All app's Dockerfiles now include HEALTHCHECK directives with 10s intervals and 30s start periods so Docker and the deploy script can reliably detect readiness

Volume Management UI for Voltage Park

Full persistent storage experience — create, browse, attach, detach, resize, and monitor volumes directly from the dashboard.

• Volumes Page (/volumes): Dedicated page to view and manage all your persistent storage volumes in one place — with status badges, provider/region info, hourly rates, and quick actions
• Create Volume Page (/create-volume): Step-by-step wizard to create a new volume — select a provider, configure name, size, region, and lifecycle settings before reviewing the cost summary

• Volume Cards: Each volume displays its name, size, provider, region, status (available, attached, creating, deleting, error), and current cost — with one-click copy for Volume ID
• Volume Details Sidebar: Click any volume to open a detailed side panel showing overview, configuration, storage usage metrics, and attached instances
• Attach to Deployment: During the deployment wizard, an "Attach Volumes" step surfaces compatible volumes (same provider and region) and lets you select one to attach before launch
  • Voltage Park instances support 1 volume per instance — the UI enforces this limit automatically
• Detach Volume: Detach a volume from a running instance directly from the instance detail sidebar or the volumes page, without losing data
• Resize Volume: Expand a volume's storage size on-demand from the volumes page (shrinking is not supported)
• Delete Volume: Delete a volume (must be detached first) with a confirmation dialog

• New Attached Volumes card visible on each running instance showing all volumes currently mounted, their size, hourly cost, and a detach action

• Volumes and Create Volume entries added to the sidebar for quick access

• Volume selection resets automatically when you switch providers or networking type in the deployment wizard
• Volume size input clamps to the provider's supported min/max range and rounds to a whole number
• Region matching is normalized so minor formatting differences (e.g. us-east-1 vs US East 1) don't prevent valid volumes from appearing
• Provider pricing is validated before allowing volume creation — a clear error is shown if pricing is unavailable for the selected provider/region

• Hourly and monthly cost estimates shown in real-time while configuring volume size
• Order summary in the create wizard shows total hourly cost and projected 30-day cost before confirming

• GET /api/volumes — list volumes (filterable by team, status, provider)
• POST /api/volumes — create volume
• GET /api/volumes/:volumeId — volume details with live usage data
