    Study Notes

    DevOps

    Continuous Integration (CI)

    • Definition: A development practice where code changes are automatically built, tested, and verified
    • Goals:
      • Reduce integration problems
      • Improve code quality
      • Reduce time-to-market
    • Key practices:
      • Automate the build process
      • Run automated tests
      • Use continuous integration tools (e.g., Jenkins, Travis CI)
    • Benefits:
      • Faster feedback loop
      • Improved collaboration
      • Reduced errors and bugs

    Containerization

    • Definition: A lightweight and portable way to deploy applications
    • Key concepts:
      • Containers: Isolated, ephemeral, and portable environments
      • Images: Templates for creating containers
      • Volumes: Persistent storage for data
    • Containerization tools:
      • Docker: Most popular containerization platform
      • Kubernetes: Container orchestration system
    • Benefits:
      • Isolation and portability
      • Efficient use of resources
      • Simplified deployment and scaling

    Git

    • Definition: A version control system for tracking changes in code
    • Key concepts:
      • Repositories (repos): Centralized storage for code
      • Commits: Snapshots of code changes
      • Branches: Isolated lines of development
    • Git workflow:
      1. Create a local repository
      2. Make changes and commit them
      3. Push changes to a remote repository
    • Git benefits:
      • Version control and tracking
      • Collaboration and branching
      • Flexibility and scalability

    DevOps

    Continuous Integration (CI)

    • Code changes are automatically built, tested, and verified to reduce integration problems and improve code quality.
    • Goals of CI include reducing time-to-market and improving collaboration.
    • Automating the build process, running automated tests, and using continuous integration tools like Jenkins and Travis CI are key practices.
    • CI provides a faster feedback loop, improves collaboration, and reduces errors and bugs.

    Containerization

    • Containerization is a lightweight and portable way to deploy applications, providing isolated, ephemeral, and portable environments.
    • Key concepts include containers, images, and volumes, with Docker being the most popular containerization platform.
    • Kubernetes is a container orchestration system, providing efficient use of resources, isolation, and portability.
    • Benefits of containerization include simplified deployment and scaling.

    Git

    • Git is a version control system for tracking changes in code, with repositories (repos) serving as centralized storage for code.
    • Key concepts include commits, which are snapshots of code changes, and branches, which are isolated lines of development.
    • The Git workflow involves creating a local repository, making changes and committing them, and pushing changes to a remote repository.
    • Git benefits include version control and tracking, collaboration and branching, and flexibility and scalability.
