50 Kubernetes Concepts Every Devops Engineer Should Know 2021 Free Pdf

A design pattern where a secondary container runs alongside the main application container within the same Pod, sharing the same lifecycle. Part 3: Configuration & Storage

A set of rules used by the scheduler to determine where a pod can be placed based on labels on nodes. 44. Pod Affinity / Anti-Affinity

Defines the minimum number of replicas or percentage of an application that must remain up during voluntary disruptions, protecting application availability. 49. Liveness, Readiness, and Startup Probes

Manages the deployment of stateful applications. It provides guarantees about the ordering and uniqueness of pods. 16. DaemonSet A design pattern where a secondary container runs

A container running alongside the main application container. It extends or enhances its capabilities (e.g., logging, service mesh). 13. ReplicaSet

If you want, I can:

Specifications that control traffic flow at the IP block or port level, functioning as a built-in firewall for Pod communication. Pod Affinity / Anti-Affinity Defines the minimum number

The default Kubernetes service type. It exposes the service on a cluster-internal IP, making it reachable only from within the cluster. 23. NodePort

The primary resource matching your request is the book 50 Kubernetes Concepts Every DevOps Engineer Should Know by Michael Levan, published by Packt Publishing. Accessing the PDF and Resources

Networking 21. ClusterIP, NodePort, LoadBalancer — Service types. 22. Service — stable network endpoint for pods. 23. Ingress & Ingress Controller — HTTP routing into cluster. 24. NetworkPolicies — pod-level network control (ACLs). 25. CNI plugins — Container Network Interface implementations. 26. DNS (CoreDNS) — service name resolution. 27. Service Mesh (e.g., Istio) — advanced traffic, observability, security. It provides guarantees about the ordering and uniqueness

The cluster-wide DNS server. It resolves service names to internal IP addresses automatically. 27. CNI (Container Network Interface)

Provides an identity for processes that run in a Pod, controlling what permissions they have inside the Kubernetes API.

Allows Pods to consume information about themselves (such as their own IP address or namespace) without connecting directly to the Kubernetes API.

Links your cluster into your cloud provider's API, separating the components that interact with the cloud platform from components that only interact with your cluster.
