Rolling-Update

Kubernetes Fundamentals: Orchestrating Containers at Scale Kubernetes helps run containers across many machines. It schedules workloads, restarts failed apps, and coordinates updates so services stay available. This makes it easier for teams to deploy modern applications, whether they run in the cloud or on premises. A cluster has two main parts: the control plane and the worker nodes. The control plane decides where to run tasks and tracks the desired state. The nodes actually run the containers, grouped into pods. Pods are the smallest deployable units and usually hold one container, but can host a few that share storage and network. Deployments manage the lifecycle of pods, while Services expose them inside the cluster or to users outside. ...

Kubernetes Deep Dive: Orchestrating Modern Apps Kubernetes helps teams run apps reliably in production by coordinating containers across many machines. It handles failures, schedules work, and scales resources as demand changes. This guide walks through the core ideas and practical patterns you can use in real projects. At a high level, Kubernetes turns a collection of containers into a managed workload. It uses a control plane to store the desired state and a data plane to run the actual containers. You define what you want with manifests, and Kubernetes figures out how to achieve it. The result is consistent deployments, easier upgrades, and faster recovery from problems. ...

Kubernetes and Orchestration Essentials Container apps run across many machines, and Kubernetes helps manage them reliably. It assigns work, scales to demand, and restarts components when needed. With Kubernetes, you express what you want in a declarative way, and the system handles the how. This guide covers the core ideas and practical steps so you can start exploring with confidence. Core concepts in Kubernetes include pods, deployments, services, and several helpers for stateful workloads. A pod is the smallest unit, usually hosting one or more containers. A deployment watches the desired number of pods and performs rolling updates when things change. A service creates a stable access point for pods, so users and other services can reach the app without knowing where each pod runs. For apps that keep state, statefulsets provide stable identities and ordered startup. Configuration data lives in ConfigMaps, while Secrets keep sensitive values out of code. Health checks, in the form of liveness and readiness probes, help the platform detect failures and route traffic only to healthy instances. ...

Containers in Production: Best Practices and Patterns Containers simplify deployment and scale, but they need careful handling to stay reliable in production. This guide highlights practical patterns you can apply across teams and environments. Start with solid foundations. Build small, purpose‑built images and use multi‑stage builds to keep runtime footprints tiny. Pin base image versions and prefer digest pins when possible. Regularly scan for vulnerabilities and rebuild after the supply chain changes. A fresh image that is missing a critical update can break your service just as quickly as a buggy code change. ...
