Build reliable Kubernetes delivery with GitOps that scales across teams, clusters, and environments.
Shipping on Kubernetes can stall when pipelines push directly to clusters, secrets sprawl, and rollbacks depend on custom scripts. This book replaces that fragility with a clear GitOps workflow where Argo CD or Flux reconciles declarative state, CI produces signed artifacts, and promotion moves through pull requests you can review and audit.
You get practical patterns that align with real platforms, from progressive rollouts and traffic shaping to multi cluster management and policy enforcement, so you can move faster without trading away safety.
- Set up Argo CD and Flux, define Applications and Kustomizations, and use ApplicationSets and image automation for fleets
- Integrate Helm and Kustomize cleanly, manage OCI registries, and keep environments consistent with overlays
- Build CI with Tekton or hosted systems, wire GitHub Actions GitLab CI and CircleCI to open promotion pull requests
- Manage secrets with SOPS and External Secrets Operator, integrate cloud KMS and Vault, and avoid plaintext in repos
- Adopt secure supply chain practices with Cosign signatures, SBOMs, Kyverno policies, and SLSA provenance
- Run progressive delivery using Argo Rollouts and Flagger, add Prometheus analysis, and shape traffic with Gateway API and service meshes
- Operate multi cluster topologies, use Argo ApplicationSet generators, Flux multi cluster bootstrap and sharding, and tenant isolation
- Provision infrastructure with Crossplane and Cluster API using GitOps, not imperative scripts
- Instrument reconciliation health, integrate Prometheus Grafana and alerting, and track DORA metrics for delivery performance
- Apply enterprise patterns for access control, audit, compliance automation, and safe emergency procedures
This is a code heavy guide with working YAML, Bash, Helm, and Tekton examples that you can adapt directly to real projects.
