The Basics of CD/CI Pipelines
Modern software development requires Continuous Integration (CI) and Continuous Deployment (CD), which allow teams to release code updates more regularly and consistently. These practices are commonly implemented using CI/CD pipelines, which automate software development and deployment processes.
Continuous Integration (CI)
Code is routinely integrated into a shared repository by developers who use the continuous integration development practice—ideally several times daily. Building the project and comparing it to the build allows automated tests to be run against each integration. This approach will reduce the time required to validate and release new software updates, improve software quality, and quickly identify and fix integration errors.
Continuous Deployment (CD)
Continuous Deployment builds on Continuous Integration by automatically deploying all code changes to a testing or production environment following the build stage. Teams can provide users with new features, updates, and fixes faster by ensuring the software can be deployed whenever needed. By reducing manual intervention, CD speeds up and improves the reliability of the deployment process.
Common Tools and Platforms Used for CI/CD
Here are some common tools and platforms used for CI / CD –
- Jenkins: This open-source automation server helps with project development, deployment, and automation. It has hundreds of plugins. Jenkins’ large plugin ecosystem makes it customizable and popular.
- GitLab CI/CD: GitLab’s source control and issue tracking features create a seamless CI/CD pipeline experience. It is known for its GitLab integration and usability.
- GitHub Actions: Build, test, and deployment cycles in GitHub repositories are automated by this CI/CD feature. Teams using GitHub for version control will find GitHub Actions easy to use, with support for numerous languages and frameworks.
