Setup Jenkins in MacOS and Build your first Jenkins job.
What is Jenkins?
Jenkins is an open source automation server. It helps automate the parts of software development related to building, testing, and deploying, facilitating continuous integration and continuous delivery.
It’s an automation server used to build and deliver software projects.
Benefits of using Jenkins
A major benefit of using Jenkins is that it has a lot of plugins available. There is easier to use CI software available, but Jenkins is open-source, free, and it is still very popular.
Why we use Jenkins for CI/CD?
Jenkins can really help you to release software in short cycles and then ensure its reliability because we are going to test and build the software over and over again. In practice, CI and CD means that we are going to verify and publish work by triggering automated builds and tests. And Jenkins is a tool that we can use for that. We are going to do these automated builds and tests.
