1. What is DevOps and why is it important?
- DevOps is a set of practices that automates and integrates processes between software development and IT teams to enhance collaboration and efficiency. Itโs important because it shortens development cycles, increases deployment frequency, and delivers reliable software faster.
2. Explain the difference between DevOps and Agile.
- Agile focuses on iterative development and collaboration between teams (developers, QA, etc.) within the development cycle, while DevOps extends that collaboration to include operations, with an emphasis on continuous integration and continuous delivery (CI/CD).
3. What are the key benefits of implementing DevOps?
- Faster delivery of features, improved collaboration between teams, more reliable and frequent releases, better infrastructure management, and faster detection and resolution of issues.
4. What are the main components of a DevOps pipeline?
- Source control, build automation, testing, deployment, and monitoring.
5. What is the role of CI/CD in DevOps?
- CI/CD automates the process of integrating and deploying code changes. It enables teams to continuously integrate code into a shared repository (CI) and deploy that code to production or other environments (CD).
6. How do you approach infrastructure as code (IaC)?
- IaC involves managing and provisioning infrastructure through code, making it repeatable, versioned, and testable. Tools like Terraform, AWS CloudFormation, and Ansible are used for implementing IaC.
7. What are some common DevOps tools and their uses?
- Jenkins (CI/CD), Docker (containerization), Kubernetes (orchestration), Terraform (IaC), Ansible (automation), Git (version control).
8. Explain the concept of "Shift Left" in DevOps.
- "Shift Left" means incorporating testing, security, and other checks earlier in the development process to identify and fix issues faster.
9. What is the difference between CI & CD?
- CI (Continuous Integration) involves automating the integration of code changes into a shared repository. CD (Continuous Delivery/Deployment) automates the deployment of changes to production or other environments.
10. How do you handle version control in a DevOps environment?
- Use tools like Git to maintain version control, ensuring all code changes are tracked, branched, and merged effectively, while adhering to branching strategies like GitFlow.
11. What is a CI/CD pipeline?
- A CI/CD pipeline automates the process of building, testing, and deploying code, ensuring faster and more reliable delivery of applications.
12. How do you implement a CI/CD pipeline from scratch?
- Set up a version control system (e.g., Git), choose a CI/CD tool (e.g., Jenkins, GitLab CI), define build and test steps, automate deployments, and integrate monitoring.
13. What are the common stages of a CI/CD pipeline?
- Source, build, test, deploy, and monitor.
14. How do you manage secrets in a CI/CD pipeline?
- Use tools like HashiCorp Vault, AWS Secrets Manager, or Kubernetes secrets to securely store and manage secrets.
15. Explain the importance of automated testing in CI/CD.
- Automated testing ensures code quality by identifying bugs early, reducing manual intervention, and speeding up the release process.
16. How do you ensure that deployments are zero-downtime?
- Use techniques like blue-green deployment, canary releases, or rolling updates.
17. What tools do you use for CI/CD?
- Jenkins, GitLab CI, CircleCI, Travis CI, AWS CodePipeline.
18. How do you handle rollbacks in CI/CD?
- Implement automated rollback mechanisms, maintain versioned artifacts, and use strategies like blue-green deployment to roll back easily.
19. What is the purpose of artifact repositories in CI/CD?
- Artifact repositories (e.g., Nexus, Artifactory) store and manage binary files and other artifacts generated during the build process.
