Jenkins Assignment

1] Create two Jenkins pipeline in github that checkouts, test, build and deploys the java application to a tomcat server

• Using declarative pipeline with name jenkinsfile.declarative

• using scripted pipeline with name jenkinsfile.groovy

• Add the "Deploy to container" Plugin

  

  • jenkins declarative pipeline code

  • 

• 

• 

• Jenkinsfile.groovy file code

• 

2] Set up a freestyle jenkins job that builds java-app whenever changes are pushed to a git repository. Use webhook trigger

• While configuring the project, in Build Triggers, u should choose GitHub hook trigger for GITScm polling

• In the settings of the github repo, go to webhook & copy paste the url of the jenkins server:- http://<url>:8080/github-webhook/

• & whenever a commit happens in SCM, it will hit the url which we have saved in the webhook section and the build will happen automatically

3] Configure jenkins to send email notifications informing status of the job. It should include Jobname, Build no, Job url. It should be done in both Freestyle and Pipeline jobs

• go to Manage Jenkins -> System, & make the necessary email related configurations

• 

4] Setup multi-branch pipeline for a repo having 4 branches & build each branch whenever changes are found in a respective branch. Setup webhook for this

• Create a job using multibranch pipeline.

• Add the Branch Sources → Git → Project Repository and save.

• To use the webhook in Multibranch Pipeline we need to install Multibranch Scan Webhook Trigger in Manage Jenkins → Plugins.

• Add webhook to our repo on GitHub

• 

• Add webhook token to Jenkins in Scan Multibranch Pipeline Triggers → Scan by webhook → Trigger token

• 

• make some changes in a branch

• & it will trigger the build

• 

5] Write a pipeline having 4 stages with below configs

• 2 agents & run 2 stages in each

• Triggers (periodic, pollscm)

• Setup 3 env var & use in pipeline steps

• pass values dynamically for above 3 var (string,choice,boolean)

• use any 4 global var inside pipeline

• Conditionals, 3rd stage should run only after 2nd stage success & 4th stage should run only after 3rd stage successs

• also 3rd stage should run only when checkout branch is master, dev

• Credentials-- secret text, username & password

• Post actions to send mail

6] create 2 global roles, 2 item roles. Assign each item role to any 2 jobs. As well asign each global role to one user

• Install Role-based Authorization Strategy Plugin

  Manage Jenkins -> Plugins -> Available Plugins -> Role-based Authorization Strategy -> install

• Once we install the plugin, then Select Role Based Strategy under authorisation Manage Jenkins -> Security -> Authorization -> Select Role Based Strategy -> Save

• Once we select Role Based Strategy we get the new option available in manage Jenkins named “Manage and Assign Roles”

  Manage Jenkins -> Manage and Assign Roles -> Assign Roles

• 

  Assigning each item role to any 2 jobs

  Manage Jenkins -> Manage and assig Roles -> Manage Roles -> Item Roles (create item Roles)

• 

  To Assign item Roles – Manage Jenkins -> Manage and Assign Roles -> Assign Roles
