3.2. 将示例管道从 Jenkins 迁移到 OpenShift Pipelines
您可以使用以下等同的示例来帮助将构建、测试和部署管道从 Jenkins 迁移到 OpenShift Pipelines。
3.2.1. Jenkins 管道
考虑在 Groovy 中编写的 Jenkins 管道，用于构建、测试和部署：
pipeline {
agent any
stages {
stage('Build') {
steps {
sh 'make'
}
}
stage('Test'){
steps {
sh 'make check'
junit 'reports/**/*.xml'
}
}
stage('Deploy') {
steps {
sh 'make publish'
}
}
}
}3.2.2. OpenShift Pipelines 管道
要在 OpenShift Pipelines 中创建相当于前面的 Jenkins 管道的管道，您需要创建以下三个任务：
build 任务 YAML 定义文件示例
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: myproject-build
spec:
workspaces:
- name: source
steps:
- image: my-ci-image
command: ["make"]
workingDir: $(workspaces.source.path)
test 任务 YAML 定义文件示例
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: myproject-test
spec:
workspaces:
- name: source
steps:
- image: my-ci-image
command: ["make check"]
workingDir: $(workspaces.source.path)
- image: junit-report-image
script: |
#!/usr/bin/env bash
junit-report reports/**/*.xml
workingDir: $(workspaces.source.path)
deploy 任务 YAML 定义文件示例
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: myprojectd-deploy
spec:
workspaces:
- name: source
steps:
- image: my-deploy-image
command: ["make deploy"]
workingDir: $(workspaces.source.path)
您可以按顺序组合三个任务以在 OpenShift Pipelines 中组成管道：
示例：用于构建、测试和部署的 OpenShift Pipelines 管道
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: myproject-pipeline
spec:
workspaces:
- name: shared-dir
tasks:
- name: build
taskRef:
name: myproject-build
workspaces:
- name: source
workspace: shared-dir
- name: test
taskRef:
name: myproject-test
workspaces:
- name: source
workspace: shared-dir
- name: deploy
taskRef:
name: myproject-deploy
workspaces:
- name: source
workspace: shared-dir
