Jenkins Contd

  • We use Jenkins to create CI/CD pipelines which generally starts from the version control system like git.
  • We need to clone the code and start building a package.
  • Building a package depends on the language of your application.
  • Cloning the code from git
    • git url
    • credentials (username/password or ssh key)
    • branch
  • Lets consider the following two java opensource applications

    • spring pet clinic:
      • developed in java
      • requires jdk 11
      • repo url: Refer Here
      • Lets clone
    • Open MRS:
      • developed in Java
      • This is open medical record system
      • repo url: Refer Here
  • Jenkins will provide User Interfaces to help us increase the pace of creating cicd pipelines. These User Interfaces are added to jenkins by a concept called as plugins.
  • While installing jenkins we have executed install plugins
  • The UI below is from a plugin called as git plugin
  • Lets clone openmrs
  • Lets consider the following .net opensource application and clone it
  • nop commerce
  • default branch: develop
  • Create a new jenkins job to clone the code Refer Here for repo url
  • Clone the odoo Refer Here with default branch as v15.0
  • As discussed in the session, We can clone code from git repo (public or private).
  • Now we should be able
    • to create the package/build from the cloned code.
    • unit test the code and show the test results
  • The above steps change from technology (java, .net, python, nodejs)
  • To understand the build system and the unit test lets start by learning a tool called as maven, which helps in build a package for java based languages.
