Symptom & Impact

Container deployments fail when image pulls or writes hit disk limits.

Environment & Reproduction

Ubuntu 16.04 Docker host with high churn in images and containers.

Root Cause Analysis

Accumulated unused images, volumes, and logs consume Docker storage.

Quick Triage

Step-by-Step Diagnosis

Identify largest reclaimable layers, stopped containers, and orphaned volumes.

Solution – Primary Fix

Prune unused Docker artifacts and expand storage where necessary.

Solution – Alternative Approaches

Relocate Docker data-root to a larger dedicated volume.

Verification & Acceptance Criteria

Image pulls complete and daemon reports sufficient free space.

Rollback Plan

Restore required images from registry and revert data-root migration.

Prevention & Hardening

Apply retention policies for logs and stale container artifacts.
