Overview

This epic focuses on building the Linux fundamentals required for DevOps work. It is an operational tool, not an academic subject.

Goals

By the end of this epic, you should be able to:

  • Confidently navigate Linux systems
  • Understand and manage permissions safely
  • Debug basic system‑level issues
  • Operate comfortably inside servers, containers, and CI environments

Included Topics

  • Filesystem & navigation
  • Permissions & ownership
  • Processes & services (systemd basics)
  • Logs & troubleshooting essentials

Excluded (for now)

  • Kernel internals
  • Legacy admin workflows
  • Deep filesystem theory
  • Topics not required for DevOps operations

Work Cards

Each work card follows a fixed cycle:

  1. Identify minimum required commands
  2. Practice in a live Linux environment
  3. Record a short demo (≤ 5 minutes)
  4. Write a focused blog post
  5. Update this epic dashboard
  6. Move Trello card forward

The Filesystem & Navigation work card has already been posted.

Relevance to DevOps

Linux skills from this epic directly support:

  • Container runtime behavior
  • CI/CD job execution
  • Cloud VM management
  • Log‑based debugging
  • Permission issues in pipelines

Linux is not learned in isolation — it is revisited as new tools are added. Earlier topics may be revisited after Docker or CI/CD exposure. Completion means operational comfort, not theoretical mastery.

Permissions & Ownership

Focus: Understanding access control without breaking systems.

Linux for DevOps is about control, observability, and confidence — not memorization.
