Jenkins 管道和共享库之间的区别

Question

I wanted to get a clear understanding of the difference between Jenkins pipeline and Shared library concept. If someone using it can you kindly clarify. Thanks!

Answer 1

I found this documentation for the Shared library. Hope this might help https://jenkins.io/doc/book/pipeline/shared-libraries/

Here is an example for the same: https://tomd.xyz/jenkins-shared-library/

Answer 2

A Jenkins Pipeline is usually one of many configurations that Jenkins has. A Pipeline is a very generic term for logic that is executed on a git repository for example.

On the other hand a shared library is like the name says a library that contains a specific function or logic. This specific function can be imported for multiple Jenkins Pipelines. A use case would be to prevent duplicate code.

An example would be you have a function that prints Hello World . Instead of writing the function 4 times for 4 Jenkins Pipelines - You create a shared library and import the function in each Pipeline. Basically just the base concept of libraries for programming languages.

The official documentation describes it pretty well too:

As Pipeline is adopted for more and more projects in an organization, common patterns are likely to emerge. Oftentimes it is useful to share parts of Pipelines between various projects to reduce redundancies and keep code "DRY".
