DevOps is a set of practices that automates the processes between software development and IT teams so they can build, test, and release software faster and more reliably.
The goal of DevOps is to shorten the software development life cycle and provide continuous delivery and integration of code changes.
Continuous Integration (CI) is a practice in which developers regularly merge their code changes into a shared code repository.
Continuous Deployment (CD) is a practice in which code changes are automatically deployed to production.
CI/CD is the combination of these two practices.
CI/CD helps to ensure that code changes are automatically tested and deployed to production with minimal manual intervention. This helps to reduce the risk of errors and improves the speed of delivery.
There are a few steps you need to take in order to set up CI/CD:
Choose a code repository (e.g. GitHub) and create a project.
Set up a continuous integration server (e.g. Jenkins) to automatically build and test code changes.
Set up a continuous deployment server (e.g. AWS Elastic Beanstalk) to automatically deploy code changes to production.
Configure your code repository and continuous integration server to work together.
Configure your continuous deployment server to pull code from your code repository.
Test your setup by making a code change and pushing it to your code repository.
CI/CD can help to improve the quality of your code and the speed of delivery.
It can also help to reduce the risk of errors and improve collaboration between development and operations teams.
CI/CD can be complex to set up and maintain.
It can also be difficult to integrate with existing systems and processes.
