Docker

Docker standardizes how applications are packaged, shipped, and run. Containers provide consistency from dev to production and simplify dependency management.

Why Docker matters in DevOps

  • Reproducible environments — “Works on my machine” becomes “works everywhere”
  • Isolation — Processes, filesystem, and networking in lightweight isolation
  • Efficiency — Share the host kernel; start and stop in seconds
  • CI/CD fit — Build once, run anywhere; ideal for pipelines

What we cover

We’ll add guides on Dockerfiles, multi-stage builds, Docker Compose for local stacks, networking, volumes, and integrating Docker with Traefik and other tools. Content is coming soon.
