GitFlow — What It Is and How to Use It GitFlow is a popular branching model for Git that defines a clear structure for feature development, releases, and hotfixes. It’s often used in DevOps and software teams to organize parallel development, testing, and deployment. 🧩 Core Idea GitFlow defines specific branches for different stages of the software lifecycle. Each branch has a clear purpose, which helps maintain stability in production while allowing parallel feature development. ...

Deploying applications to Kubernetes? Follow these best practices to avoid downtime, improve scalability, and simplify operations. 1. Use Readiness and Liveness Probes Probes help Kubernetes know when your app is healthy and ready to serve traffic. livenessProbe: httpGet: path: /healthz port: 8080 initialDelaySeconds: 5 periodSeconds: 10 readinessProbe: httpGet: path: /ready port: 8080 initialDelaySeconds: 5 periodSeconds: 10 2. Configure Resource Requests and Limits Avoid over/under-scheduling: ...

How to Distribute Load Effectively in Kubernetes Managing and distributing load in a Kubernetes cluster is key to ensuring system performance and reliability. Kubernetes offers several native features that help balance traffic and workload across nodes and pods. Why Load Distribution Matters Evenly distributed load improves: System responsiveness Resource utilization Cluster stability Cost-efficiency 1. Horizontal Pod Autoscaler (HPA) HPA automatically scales pods based on CPU/memory or custom metrics. kubectl autoscale deployment myapp --cpu-percent=50 --min=2 --max=10 Ensure metrics-server is installed for HPA to function. ...

Why Dockerfile Best Practices Matter Poorly written Dockerfiles lead to large, insecure, and hard-to-maintain container images. Following best practices ensures faster builds, smaller images, better security, and improved maintainability. 1. Use Official or Minimal Base Images Choose minimal or well-maintained base images like: FROM alpine:3.19 # or FROM python:3.11-slim 2. Pin Versions Explicitly Avoid surprises by pinning versions of dependencies and packages: RUN apt-get install -y curl=7.68.0-1ubuntu2.6 3. Combine RUN Commands Reduce layers by chaining commands: ...
