In this article, we will get to know about the CI-CD pipeline and how pipelines do not just help developers make code easier to manage and deploy but also saves DevOps professionals a huge amount of time.

Nowadays, almost all professionals frequently work with pipelines. Pipelines automatically build and test code projects to make them available to others and work with just about any programming language or project type.

CI/CD is one of the best practices for DevOps teams to implement. It is also an Agile methodology best practice, as it enables software development teams to focus on meeting business requirements, code quality, and security because deployment steps are automated.

Let’s discuss more this.

What does CI and CD means?

CI, short for Continuous Integration, is a software development practice in which all developers merge code changes in a central repository multiple times a day.

Due to the scale of requirements and the number of steps involved, this process is automated to ensure that teams can build, test, and package their applications in a reliable and repeatable way. CI helps streamline code changes, thereby increasing time for developers to make changes and contribute to improved software. The entire CI feedback loop should run in less than 10 minutes.

CD stands for Continuous Delivery, which on top of Continuous Integration adds the practice of automating the entire software release process.

It picks up where continuous integration ends. CD automates the delivery of applications to selected infrastructure environments. Most teams work with multiple environments other than the production, such as development and testing environments (Staging), and CD ensures there is an automated way to push code changes to them.

Why is CI/CD important?

  • CI/CD allows organizations to ship software quickly and efficiently.
  • The pipelines are designed for businesses that want to improve applications frequently and require a reliable delivery process.
  • CI/CD facilitates an effective process for getting products to market faster than ever before, continuously delivering code into production, and ensuring an ongoing flow of new features and bug fixes via the most efficient delivery method.

What are the elements of CI/CD?

A CI-CD pipeline may look like overhead, but it’s not. It is essentially a runnable specification of the steps that every developer needs to perform to deliver the new releases of the software or product. Without the automated pipelines, developers used to follow the manual process of the deployment, this seems to be less productive.

Failure in each stage typically triggers a notification — via email, Slack, etc. — to let the responsible developers know about the cause. Otherwise, the whole team receives a notification after each successful deployment to production.

A CI-CD pipeline is split into a set of different stages. These are generally a set of tasks that have a related function. Here are a few main pipeline stages:-

Source Stage:

A pipeline runs when we triggered or push the code to the main branch, where the automated pipeline starts to build the process. This happens due to a code change that triggers a notification to the CI/CD tool, which runs the corresponding pipeline.

Build Stage:

So here, we combine the source code and its dependencies to build a runnable instance of our product that we can probably ship to our end users. It doesn’t depend on language, a few languages which need to be compiled, such as Java, C++, Go. Other languages do not require this step.

If your product is cloud-native then this would be deployed using a Docker container.

If something is broken in the code, then the failure notification will trigger at the time of build. So, it would be easy to find the issue and fix it immediately.

Test Stage:

In this stage, we run the automated test to validate the accuracy and the behavior of our product code. It will help development teams know whether a software build passes or fails.

Deploy Stage:

So, we have already built the package and run the test cases. If all the stages are passed, then we are ready to deploy it. And the new release will be deployed in multiple environments such as Development, Staging environments for the Dev and QA purpose. It is also deployed in the production environment for the end-users.
