DevOps

DORA metrics and batch size, trunk-based development, immutable artifacts, containers, Kubernetes, Terraform, CI pipelines, canary deploys, secrets, flags, observability and SLOs.

Developer-centric: images and layers, Dockerfiles and the layer cache, multi-stage builds, build secrets, ports, volumes, Compose, microservices, graceful shutdown and debugging.

The six objects a developer writes: Pods, Deployments and rollouts, probes, requests and limits, config and secrets, Services and Ingress, microservices and cascading failure, plus kubectl and debugging.

Forty sections: value streams, Git internals, reproducible builds, cgroups, Kubernetes architecture, Terraform state, GitOps, migrations, OpenTelemetry, error budgets and cost.
