Kubernetes Development
Explore the world of Kubernetes for modern application development and deployment. Learn how to build, deploy, and manage containerized applications at scale.
Getting Started with Kubernetes
Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications. It groups containers that make up your application into logical units for easy management and discovery.
- Pods: The smallest deployable units of computing that can be created and managed in Kubernetes.
- Deployments: Provide declarative updates for Pods and ReplicaSets.
- Services: Abstracting application-specific logic across multiple Pods.
Developing Cloud-Native Applications
Building applications designed to run on Kubernetes requires a different approach. Embrace microservices, containerization, and CI/CD pipelines for efficient development workflows.
Example: Basic Kubernetes Deployment
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-app-deployment
spec:
replicas: 3
selector:
matchLabels:
app: my-app
template:
metadata:
labels:
app: my-app
spec:
containers:
- name: my-app-container
image: nginx:latest
ports:
- containerPort: 80
Key Concepts and Tools
Understand the core components and influential tools in the Kubernetes ecosystem:
- kubectl: The command-line tool for interacting with Kubernetes clusters.
- Helm: A package manager for Kubernetes, simplifying the deployment of complex applications.
- Prometheus & Grafana: For monitoring and visualization of your Kubernetes workloads.
- Istio: A service mesh that provides traffic management, security, and observability.
