While CICD gets thrown around a lot, it actually refers to two separate practices that work together in the software development lifecycle: Continuous Integration (CI) and Continuous Delivery/Deployment (CD).
Here's a quick breakdown:

We often use Dockerfile to build Docker images. There are many basic and essential things that we should keep in mind when we write a Dockerfile. Generally, people do ignore or fail to follow the practices.
- Always use a .dockerignore file to exclude unnecessary files and directories. It helps to increase the build performance.
- We should use trusted base images only. Keep updating the images periodically to avoid any vulnerabilities.
- Don't run as a root user. Run as a Non-Root User to avoid security breaches.
- Always use specific tags over the latest tag for the image to avoid breaking changes over time and for any confusion.
- Use multi-stage builds to create smaller and more efficient images.
- Try to avoid using multiple RUN commands as it creates multiple cacheable layers which will affect the efficiency of the build process.
- Minimize the number of layers by consolidating the instructions to increase the build’s performance and time.
- Use the semantic versioning method for docker image tagging.

To demonstrate Blue-Green deployment, we’ll use AWS ECS to host our Swiggy-clone application. ECS is a highly scalable container orchestration service provided by AWS.
AWS CodePipeline is a fully managed continuous integration and continuous delivery (CI/CD) service that automates the build, test, and deployment phases of your release process. Let’s see how to set up a Blue-Green deployment pipeline using AWS CodePipeline:
