3.2. Jenkins から OpenShift Pipelines へのサンプルパイプラインの移行
以下の同等の例を使用して、Jenkins から OpenShift Pipelines へのパイプラインのビルド、テスト、およびデプロイを支援できます。
3.2.1. Jenkins パイプライン
ビルド、テスト、デプロイ用に Groovy で記述された Jenkins パイプラインを検討します。
pipeline { agent any stages { stage('Build') { steps { sh 'make' } } stage('Test'){ steps { sh 'make check' junit 'reports/**/*.xml' } } stage('Deploy') { steps { sh 'make publish' } } } }
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 パイプライン
前の Jenkins パイプラインと同等のパイプラインを OpenShift Pipelines で作成するには、次の 3 つのタスクを作成します。
build
タスクの YAML 定義ファイルの例
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)
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
タスクの YAML 定義ファイルの例
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)
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
タスクの YAML 定義ファイルの例
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)
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)
3 つのタスクを順番に組み合わせて、OpenShift Pipelines でパイプラインを形成できます。
例: ビルド、テスト、およびデプロイのための OpenShift Pipelines
