Containerization & Orchestration #
Containers package applications with dependencies for consistency across environments. Orchestration platforms manage containers at production scale.
Docker essentials #
- build minimal, secure images
- use multi-stage builds
- run as non-root users
- scan images in CI pipelines
Kubernetes essentials #
- workloads (Deployments, StatefulSets, Jobs)
- networking (Services, Ingress, Gateway)
- configuration and secrets management
- autoscaling and rollout strategies
Production best practices #
- enforce resource requests/limits
- set health probes and disruption budgets
- standardize manifests with Helm or Kustomize
- use policy-as-code for guardrails
