CI/CD
CI/CD means making small code changes often. After each change, Jenkins automatically runs tests. If the tests pass, Jenkins releases the new code. This is better than releasing big code changes. Big changes take longer to test and fix. Small changes can be tested and released faster.
CI/CD pipelines automate the software delivery process. They help developers build, test, and deploy code changes faster and more reliably. Developers make changes to the source code in a version control system like Git. This code repository acts like a shared document. Whenever a change is made, the pipeline kicks off a pre-defined set of steps automatically:
First, an automated build compiles the code and runs tests immediately. If the tests fail, the changes are rejected. This catches errors early. Next is continuous integration. Developers frequently merge their code changes into the main branch. With each merge, builds and tests are run to ensure nothing breaks.
Then comes continuous delivery. The changes are deployed to testing/staging servers. This is like a dress rehearsal before the actual release. Finally, in continuous deployment, the changes are deployed directly to production with little manual intervention. This enables quick delivery of features to users.
In summary, CI/CD pipelines are assembly lines for software delivery. They automate the building, testing, and releasing of code changes rapidly and reliably. Developers get fast feedback if they break things. Companies can release features faster without sacrificing quality.
Understanding Jenkins CI/CD Pipeline And Its Stages
Jenkins is an open-source automation server that enables developers to reliably build, test, and deploy applications. It supports continuous integration and continuous delivery (CI/CD) workflows that allow teams to frequently deliver high-quality software. Jenkins is extremely popular, with over 100,000 installations worldwide.
At its core, Jenkins provides an automation engine with an extensive plugin ecosystem that offers integrations for practically any DevOps toolchain. This allows Jenkins to fit into diverse infrastructure setups and support all types of development processes.
