π Understanding CI/CD: Continuous Integration & Continuous Deployment
Hello, everyone! π
Today, I'm sharing a simplified guide to CI/CD, covering the essentials of Continuous Integration
and Continuous Deployment
. But, there's more to CD than meets the eye - we'll also touch on the often-overlooked aspect of Continuous Delivery
. Whether you're new to the concept or looking to brush up, this post will help you understand CI/CD in an easy-to-grasp way. Let's get started! π
π€ Continuous Integration (CI)
Imagine a Library π:
- Multiple authors (
developers
) write books (code
) and submit them to the library (repository
). - A librarian (
CI tool
) collects all the books, checks for errors, and ensures they are properly formatted. - If a book has errors, the librarian sends it back to the author for corrections.
- Once all books are error-free, the librarian creates a master copy (
build
) and stores it in the library.
Key Takeaway: CI
ensures that individual code changes are integrated into a central repository, and automated processes verify that the code is correct and functional.
π Continuous Deployment (CD)
Imagine a Restaurant π½οΈ:
- Chefs (
developers
) prepare dishes (code
) and pass them to the kitchen staff (CD tool
). - The kitchen staff checks the dishes for quality and presentation and then serves them directly to customers (
production
). - If a dish is not up to standard, the kitchen staff sends it back to the chef for rework.
- Once a dish is approved, it's immediately served to customers.
Key Takeaway: CD
automates the deployment of code changes to production, ensuring that only validated and tested code reaches the end-users.
π Continuous Delivery (CD)
Imagine a Factory π:
- Workers (
developers
) build components (code
) and pass them to the quality control team (CD tool
). - The quality control team checks the components, assembles them into a final product, and packages it for delivery.
- The packaged product is then stored in a warehouse (
repository
) until it's ready to be shipped to customers (production
). - When the product is shipped, the factory receives feedback from customers, which is used to improve the production process.
Key Takeaway: CD
ensures that code changes are built, tested, and packaged into a releasable product, which can be deployed to production at any time. It's a bridge between CI and CD.
π Conclusion
I hope these analogies have helped you understand the basics of CI/CD
. My goal is to make complex concepts simple and easy to grasp. π
