[Jenkins] Jobs will be created automatically by Jenkins Job Builder

Bạn cũng đã thấy việc tạo các job trên jenkins thì khá là phức tạo và nếu bạn không có 1 công cụ (tool) thì bạn cần chỉnh sửa rất nhiều và công việc thì lập đi lập lại.

Bằng các sử dụng jenkins builder thì công việc sẽ as Code hơn và auto hơn!

1) Install Jenkins Job buidler

sudo apt-get update
sudo apt-get install jenkins-job-builder

Tạo 1 file là jenkins_jobs.ini

[job_builder]
allow_duplicates=False
update=all

[jenkins]

2.Creating a job with Jenkins job builder

2.1) single job

chúng ta sẽ có singlejob.yaml với nội dung như sau:
singlejob.yaml — Creates the job as per the configurations in the yaml

- job:
    scm:
      - Simple-Test-Job
    builders:
      - shell: |
          TIME=`date`
          echo "It is ${TIME}"
    parameters:
      - string:
          name: BRANCH
          default: '{branch|master}'
    name: simple-test-job
    project-type: freestyle
    defaults: global
    description: 'Do not edit this job through the web!'
    disabled: false
    display-name: 'Fancy Test Job name'
    concurrent: true
    quiet-period: 5
    block-downstream: false
    block-upstream: false
    retry-count: 3
    build-discarder:
      daysToKeep: 3
      numToKeep: 20
      artifactDaysToKeep: -1
      artifactNumToKeep: -1

- scm:
    name: Simple-Test-Job
    scm:
      - git:
          url: https://github.com/etowett/apisim.git
          branches:
            - main

Bây giờ bạn thực hiện tạo job thông qua command và template của jenkins job builder.

root@work-space-u20:~/mylab-helm-chart/jenkins-job-builder# jenkins-jobs --conf jenkins_jobs.ini update singlejob.yaml 
INFO:jenkins_jobs.cli.subcommand.update:Updating jobs in ['singlejob.yaml'] ([])
INFO:root:Caching type parameters of parameters = jenkins_jobs.modules.parameters:Parameters
INFO:root:Caching type scm of scm = jenkins_jobs.modules.scm:SCM
INFO:root:Caching type builders of builders = jenkins_jobs.modules.builders:Builders
INFO:jenkins_jobs.builder:Number of jobs generated:  1

INFO:jenkins_jobs.cli.subcommand.update:Number of jobs updated: 1

Đây là hỉnh anh trên jenkins

2.2) multiple jobs

Creates multiple jobs all having the same configuration as per the job template. All the jobs will be created at one go.

multiplejobtemplate.yaml

- project:
    name: Test-Job-Template-Temp
    jobs:
      - 'Test-Job-Template-{num}':
          num: 1
      - 'Test-Job-Template-{num}':
          num: 2
      - 'Test-Job-Template-{num}':
          num: 3

- job-template:
    disabled_var:
    command: df
    type: freestyle
    scm:
      - Test-Job-Template
    builders:
      - shell: |
          TIME=`date`
          echo "{num} It is $TIME"
          echo "Job-Name Test-Job-Template-{num}"
    parameters:
      - string:
          name: BRANCH
          default: '{branch|master}'
    name: 'Test-Job-Template-{num}'
    id: 'Test-Job-Template-{num}'
    project-type: freestyle
    defaults: global
    description: 'Do not edit this job through the web!'
    disabled: false
    display-name: 'Fancy Test Job name {num}'
    concurrent: true
    quiet-period: 5
    block-downstream: false
    block-upstream: false
    retry-count: 3
    build-discarder:
      daysToKeep: 3
      numToKeep: 20
      artifactDaysToKeep: -1
      artifactNumToKeep: -1

- scm:
    name: Test-Job-Template
    scm:
      - git:
          url: https://github.com/etowett/apisim.git
          branches:
            - main

Oke giờ bạn sẽ tự phát triên

3) How to create Jenkins Job Builder from any pipeline or any XML

Mình cũng đã đặt 1 câu hỏi là làm thể nào tạo ra 1 template jenkins job builder 1 cách dễ dàng?
Có thể convert từ XML jobs to YAML của job builder không?
