How to fix VPS disk full from Docker

Troubleshoot VPS disk full from Docker by checking prune old images, review logs, and move persistent data carefully in a Docker, VPS, or Better-PaaS deployment workflow.

Overview

When VPS disk full from Docker, slow down and isolate the failure: build, runtime, networking, DNS, credentials, or resources. Better-PaaS gives you logs, deployment history, server tools, and configuration screens to work through the problem systematically.

Start here

First, prune old images, review logs, and move persistent data carefully. Then check the most recent deployment logs and confirm whether the app failed during build, startup, health check, or routing.

Step-by-step checks

Work from the app outward: source code, build output, runtime command, env vars, container health, router, DNS, then external services.

  • Read the latest logs
  • Confirm the app listens on the expected port
  • Verify required environment variables
  • Check database or service containers
  • Retry after fixing one variable at a time

Prevent it next time

Keep build scripts explicit, document env vars, set backups for stateful apps, and verify a staging deployment before switching a production domain.

FAQ

Can Better-PaaS show logs for VPS disk full from Docker?

Yes. Better-PaaS streams container logs in the dashboard and stores logs on disk for troubleshooting.

Should I redeploy immediately?

Only after changing one likely cause. Repeated redeploys without reading logs usually hide the real issue.
