SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

Diagnose devcontainer build failures and startup issues by analyzing error logs and identifying root causes. Use when container builds fail, feature installations error, startup crashes occur, or when the user pastes build logs showing errors. Also applies for "permission denied" issues, network timeouts, "failed to create" errors, or any devcontainer troubleshooting scenario — even if described as "my container won't start", "build is failing", or "feature won't install" without explicit log mentions.

Core Features & Use Cases

  • Analyze build logs to identify root causes and surface actionable remediation steps.
  • Provide step-by-step guidance for common issues like Docker daemon status, disk space, permissions, network access, and feature installation failures.
  • Offer a structured troubleshooting workflow and recommended commands to verify fixes.

Quick Start

Paste your devcontainer build logs and I will diagnose failures and propose fixes.

FAQPage Schema
How do I fix devcontainer build errors from failed feature installations?

Fix devcontainer build errors by analyzing your build logs to pinpoint the root cause of feature installation failures. The diagnosis provides concrete remediation steps addressing dependency conflicts, network timeouts, and permission issues to successfully complete the build.

Why does my devcontainer fail to start with a permission denied error?

Devcontainer startup failures with permission denied errors occur when container users lack sufficient file system or execution rights. Analyzing the build logs identifies the specific restricted path or feature, providing steps to adjust user permissions and resolve the startup crash.

What is the best way to troubleshoot Docker network timeouts during devcontainer builds?

Troubleshoot Docker network timeouts during devcontainer builds by reviewing build logs to isolate failing network requests. The diagnostic workflow checks Docker daemon status and network access, offering verification commands and remediation steps to restore connectivity.

Can I diagnose devcontainer build failures if I only have a symptom description without logs?

You can diagnose devcontainer build failures using only symptom descriptions like build is failing or container won't start. The diagnostic workflow analyzes the provided symptoms to infer root causes and propose targeted remediation steps and best-practice checks.

How do I resolve devcontainer failed to create errors and disk space issues?

Resolve devcontainer failed to create errors by checking available disk space and Docker daemon status. Analyzing the build logs isolates resource exhaustion or creation conflicts, providing structured remediation steps to clear space and verify container creation.
