"Sealed Secrets for Secure GitOps Workflows"
"Sealed Secrets for Secure GitOps Workflows" is a definitive guide for organizations and DevOps professionals seeking to elevate the security of their Kubernetes-based deployments with modern GitOps practices. This book begins by establishing the foundational concepts of GitOps, delving into its workflow architecture and the unique security threats present in declarative infrastructure. It provides nuanced threat modeling techniques and addresses the pressing regulatory and compliance challenges that arise when managing secrets at scale, offering concrete strategies for lifecycle management and the realities of dynamic infrastructure.
Drawing on deep expertise, the book explores the cryptographic design of sealed secrets, demystifying key management through public key infrastructures, cloud KMS, and hybrid trust models. Readers are guided through the integration of sealed secrets into continuous delivery pipelines such as ArgoCD, Flux, and Jenkins, with practical insights into developer tooling, automated secret management, and securing every stage of the software supply chain. Advanced topics such as fine-grained access controls, RBAC, policy enforcement, and integration with hardware security modules ensure that teams can operationalize sealed secrets in high-stakes, enterprise-grade environments.
Through detailed chapters on scaling, compliance, and observability, the book equips readers to implement robust disaster recovery, health monitoring, and distributed secret management across multi-cluster and federated environments. Rich case studies from regulated sectors provide real-world context, while forward-looking sections discuss open source innovation, emerging threats, and the evolving landscape of policy and confidential computing. Whether transitioning from legacy secret stores or seeking to automate governance, "Sealed Secrets for Secure GitOps Workflows" is an essential resource for securing the future of cloud-native operations.
