Containers & Orchestration

How containers are built, run, composed, and orchestrated at scale — from a single Dockerfile to a production Kubernetes cluster.

  • Docker

    Images, containers, Dockerfile patterns, multi-stage builds, layer caching, registries, and runtime configuration.

  • Docker Compose

    Multi-service local environments, compose-file patterns, networking between services, and volume management.

  • Kubernetes

    Core concepts, networking, storage, security, workloads, autoscaling, debugging, and reference cheatsheets. The largest domain in this knowledge base.

  • Helm

    Chart authoring, templating, value overrides, dependency management, and the full release lifecycle.

  • Kustomize

    Base/overlay patching, environment promotion, and managing Kubernetes manifests without templating.

  • containerd

    The container runtime beneath Kubernetes — concepts, configuration, and low-level operations.
