What is meant by continuous integration in Jenkins?
Continuous Integration is a software development process where a code is continuously tested after a commit, to ensure there are no bugs. With continuous integration, bugs can be identified early and fixed before pushing changes to production. Any new code is integrated into one executable form, termed as a build.
What is the architecture of Jenkins?
Jenkins Architecture The Jenkins CI server checks the repository at regular intervals and pulls any newly available code. The Build Server builds the code into an executable file. In case the build fails, feedback is sent to the developers. Jenkins deploys the build application to the test server.
What is CI build in Jenkins?
Continuous integration is a process in which all development work is integrated as early as possible. The resulting artifacts are automatically created and tested. This process allows to identify errors in an early stage of the project. The Jenkins build server is a tool to provide this functionality.
What are the main ideas of continuous integration?
Continuous integration (CI) is the practice of automating the integration of code changes from multiple contributors into a single software project. It’s a primary DevOps best practice, allowing developers to frequently merge code changes into a central repository where builds and tests then run.
Why we use Jenkins as a continuous integration server?
Jenkins facilitates continuous integration and continuous delivery in software projects by automating parts related to build, test, and deployment. This makes it easy for developers to continuously work on the betterment of the product by integrating changes to the project.

What are the main components of Jenkins master?
The following are the key Jenkins master components. Jenkins Jobs: A job is a collection of steps that you can use to build your source code, test your code, run a shell script, or run an Ansible role in a remote host. There are multiple job types available to support your workflow for continuous integration & continuous delivery.
How does continuous integration work in a project?
In Continuous Integration after a code commit, the software is built and tested immediately. In a large project with many developers, commits are made many times during a day. With each commit code is built and tested. If the test is passed, build is tested for deployment. If deployment is a success, the code is pushed to production.
