Containerd in Practice

"Containerd in Practice"
"Containerd in Practice" delivers a comprehensive and authoritative exploration of containerd, the industry-standard high-performance container runtime at the heart of today's cloud-native infrastructure. The book opens by tracing the origins and evolution of container runtimes, clearly outlining containerd's motivation, its role within a modern cloud-native stack, and its critical adherence to OCI standards. From installation, configuration, and platform support to nuanced comparisons with Docker Engine and CRI-O, readers are equipped with a robust foundational understanding crucial for any practitioner adopting containerd.
Delving deep into containerd's architecture, the book examines daemon and client models, resource isolation through namespaces, plugin development, storage abstractions, shims, and runtime integrations. Richly detailed chapters walk through image lifecycle management, including multi-platform support, image verification, and optimization strategies for robust, scalable deployments. Readers gain practical knowledge on container lifecycle, metrics, health checks, logging, and the operational intricacies of networking and storage-from CNI-based networking and advanced DNS policies to persistent volumes and filesystem security.
With a sharp focus on real-world relevance, "Containerd in Practice" covers advanced topics such as security hardening (leveraging seccomp, AppArmor, SELinux), compliance for regulated environments, and strategies for supply chain security. The book further addresses integration with Kubernetes, CI/CD workflows, and production tuning, while also providing expert guidance on troubleshooting, disaster recovery, and extending containerd through plugins and programmatic APIs. Featuring case studies and best practices for orchestrator integration, edge deployments, and custom ecosystem extensions, this resource is indispensable for engineers, SREs, and architects committed to mastering containerd in production environments.
