Important Tools and Technologies

Git & GitHub

  • What: Manage and track code changes.

  • Example: Team members can work together on code easily.

Docker & Docker Swarm

  • What: Create containers to run applications.

  • Example: Ensures your app works the same on any computer.

Jenkins (CI/CD Pipelines)

  • What: Automate building, testing, and deploying code.

  • Example: Jenkins automatically tests your app and puts it online.

Kubernetes & Helm

  • What: Manage and scale containerized applications.

  • Example: Keeps your app running smoothly even if traffic increases.

Cloud Services (AWS, GCP, Azure)

  • What: Online services to run and store applications.

  • Example: Use AWS to host your app.

Infrastructure as Code (IaC)

  • What: Manage servers and infrastructure with code.

  • Tools: Use Terraform to set up servers, Ansible for configuration.

  • Example: Set up all servers with a script.

Monitoring with Grafana

  • What: Keep track of your app’s health.

  • Example: Grafana shows how your app is performing.

Real-Time Example

Imagine you are working on a shopping website:

  • Using Git: Team members save their code in a shared place.

  • Using Jenkins: Automatically test and put new features online.

  • Using Docker: App runs the same way on any computer.

  • Using Kubernetes: App scales up if many users visit the site.

  • Using AWS: Host the website online.

  • Using Grafana: Monitor how well the website is running.

By following these steps and using these tools, you can become a successful DevOps engineer.
