Through a process of building, testing, and deploying code, Continuous Integration (CI)/Continuous Delivery (CD) pipelines will enable us to securely deploy a new version of the product. From integration and testing to delivery and deployment, it offers automation and continuous monitoring throughout the lifecycle of a software product.
Continuous Integration (CI) is the process of automating code modifications that can occur during application development, testing, or merges of the code to a shared repository.
Our ability to release the artifacts into various settings is made possible by continuous delivery (CD). In order to make sure that an application is successfully deployed to a cloud environment, we can construct automated test cases for the application. CD enables us to distribute the code to various phases through valid approvals. Every time a team member submits code changes to version control, continuous integration (CI) automatically builds and tests the updated code. A code committed to a shared repository's main, or trunk branch causes the automated build system to create, test, and validate the whole branch. By merging their modifications into the common version control repository each time, they finish a task, continuous integration (CI) encourages developers to share their code and unit tests.
Software developers frequently work alone before having to integrate their modifications into the team's overall code base. Waiting days or weeks before integrating code can result in numerous merge conflicts, difficult-to-fix issues, divergent coding practices, and redundant work. Because CI mandates that the development team's code be continually merged to the shared version control branch, it avoids these issues.
The main branch is kept current by CI. Developers can segregate their work in transitory feature branches by using contemporary version control systems like Git. The developer publishes a pull request from the feature branch to the main branch after the feature is finished. The feature branch can be deleted after the pull request is approved, at which point the modifications are merged into the main branch.
This procedure is repeated by development teams for every work item. Teams can create branch rules to guarantee the primary branch keeps the desired quality criteria.
