This course provides a practical introduction to Continuous Integration and Continuous Deployment (CI/CD), guiding learners through building automated pipelines, integrating testing, and deploying applications seamlessly using modern DevOps tools.🚀 CI/CD Course SummaryIntroduction to CI/CD – Understanding Continuous Integration (automatic testing & validation) and Continuous Deployment/Delivery (automated deployments).Benefits of CI/CD – Faster releases, reduced errors, improved collaboration, and reliable delivery.CI/CD Pipelines – Detailed breakdown of pipeline stages (build, test, deploy, monitor).Project Setup – Hands-on with EC2:Production: running services directly.Staging: containerized setup using Docker.Code management with GitHub (main & staging branches).GitHub Actions –Storing credentials securely in GitHub Secrets.Workflow setup in .github/workflows.Main branch pipeline: auto-deploy code to EC2.Staging pipeline: build Docker image → push to Docker Hub → pull & run on EC2.Covered deployments via bastion host integration.Jenkins –Installation & configuration (local and EC2).GitHub webhooks for auto triggers.Ngrok for exposing local Jenkins.Different job types: Freestyle, Multibranch, and Pipeline projects.Multibranch pipelines for branch-specific builds.Secure credential management.Deployments from bastion to private EC2 using ProxyCommand, SSH config, or double SSH.Testing, rollbacks, and pipeline notifications (Slack/Google Chat).Use of Shared Libraries, Agents, and scripting best practices.Enforcing production deployment rules (only after merge).Bitbucket Pipelines – CI/CD workflows using Bitbucket Cloud pipelines.Best Practices – Abstraction with scripts, shared libraries, staged pipelines, secure credential storage, and structured deployment flows.
