🚀 Container Orchestration

Kubernetes: Master Cluster Management

Automate deployments, scale applications, and optimize container operations in cloud-native environments.

Kubernetes Core Concepts

Pods

The smallest deployable units in Kubernetes, containing one or more containers.

Deployments

Manage application rollouts and updates with declarative configuration.

Services

Expose applications to internal and external networks with load balancing.

Namespaces

Isolate resources for multi-team environments or multiple clusters in a single physical cluster.

Why Kubernetes?

Scalability

Automatically scale applications based on resource usage or custom metrics.

  • Auto-scaling based on metrics
  • Horizontal Pod Autoscaler

Reliability

Self-healing features ensure your applications stay available during failures.

  • Auto-restart failed containers
  • Rollout rolling updates
  • Zero-downtime updates

Portability

Run on any infrastructure - on-prem, cloud, or hybrid environments.

  • Deploy to any provider (AWS, GCP, Azure)
  • Consistent deployment across environments

Getting Started with Kubernetes

Install Kubernetes

Choose your deployment method:

Minikube

For local development on any platform.

$ curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube_OS.ARCH
$ install minikube /usr/local/bin/
$ minikube start
                        

Kubeadm

For multi-node clusters in production.

$ apt-get update
$ apt-get install -y kubelet kubeadm kubectl
$ kubeadm init
                        

First Deployment

Create a deployment YAML file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 80
