SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a structured, phased approach to diagnosing and fixing issues in Docker containers, images, networks, and volumes, reducing downtime and guesswork.

Core Features & Use Cases

  • Four-phase methodology: Quick assessment, log analysis, interactive investigation, and deep analysis guide efficient triage.
  • Command-library: Curated commands for diagnosing container exits, memory issues, networking, and storage problems.
  • Use Case: When a container crashes with an unknown exit code, follow the steps to identify whether it's an application bug, misconfiguration, or resource constraint.

Quick Start

Run the following sequence to get started: docker ps -a docker logs <container> --tail 50 docker inspect <container>

Frequently Asked Questions about debug:docker

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I troubleshoot a Docker container that keeps crashing with an unknown exit code?▼

To troubleshoot a crashing Docker container, analyze the exit code and container logs to identify whether the root cause is an application bug, misconfiguration, or resource constraint. A structured diagnostic methodology guides you through quick assessment, log analysis, and deep analysis.

What is the best way to diagnose Docker container OOM and memory issues?▼

Diagnosing Docker OOM and memory issues involves using a curated command toolkit to inspect container resource constraints and log analysis. This process isolates memory exhaustion events to resolve unexpected container terminations in development or production environments.

How do I resolve Docker networking and volume mounting problems in production?▼

Resolving Docker networking and volume mounting problems requires interactive investigation and deep analysis phases. By applying specific diagnostic commands, you can identify misconfigurations in container networks and storage mounts to restore connectivity and data access.

Can I use a structured approach to debug Docker images that fail to start?▼

Yes, you can debug Docker images that fail to start using a four-phase methodology covering quick assessment, log analysis, interactive investigation, and deep analysis. This structured approach reduces guesswork and downtime across development, testing, and production environments.

Why does my Docker container fail to start and how can I quickly assess it?▼

A Docker container may fail to start due to misconfigurations, missing dependencies, or resource limits. Quickly assess the failure by running status checks and inspecting container logs to triage the issue before proceeding to deeper interactive investigation.
