CI/CD & DevOps

Automating the path from commit to production: pipelines, containers, deployment strategies, and GitOps.

Concepts

Continuous integration and continuous delivery — automating the path from commit to a shippable build.

Packaging an app with its dependencies via containers, and how Kubernetes schedules and manages them at scale.

Different ways to roll a new version out safely, trading off speed, blast radius, and infrastructure cost.

Keeping infrastructure and application configuration consistent, versioned, and reproducible across environments.

Using a Git repository as the single source of truth for infrastructure and deployment state.

Keeping credentials and keys out of source control and pipeline logs, while still letting automation use them.
