Kubernetes evolved from Google's internal Borg system to become the leading open-source container orchestrator.
Containers standardize application packaging, while tools like Docker Swarm and Docker Compose address orchestration needs at different scales.
Use the kubectl command-line tool and declarative YAML manifests to manage and configure your Kubernetes cluster resources.
The master node manages the cluster's state and schedules work, while worker nodes execute the actual containerized applications.
A Pod is the smallest deployable unit in Kubernetes, acting as a logical wrapper for one or more containers.
Deployments manage ReplicaSets to ensure a specified number of pod replicas are running and to control rolling updates.
A DaemonSet ensures that a copy of a pod runs on all or a specific subset of nodes in the cluster.
Services provide stable internal networking and load balancing for pods, while Ingress manages external HTTP/S access to those services.
Decouple sensitive information and configuration from your application code using Secrets and ConfigMaps.
Persistent Volume Claims allow stateful applications like databases to request and mount durable storage that outlives the pod lifecycle.
Namespaces function as virtual clusters within a single physical cluster, allowing you to partition resources between different teams or projects.
A complete request flows from an external user through a cloud load balancer, Ingress, Service, and finally to a Pod running the application.
A real-world webshop example demonstrates how to structure microservices like APIs and databases using various Kubernetes resources.
Kubernetes acts like a postal service for your applications, where you define the destination and it handles all the complex delivery logistics.
Key questions are answered regarding Kubernetes's promise theory, self-healing capabilities, and its suitability for small versus large projects.
