使用 Jenkins 作业将 Helm 图表部署到 Kubernetes
Pet*_*zov 5 jenkins jenkins-groovy jenkins-pipeline
我想创建一个 Jenkins 作业，将 Helm Chart 部署到 Kubernetes 集群中。Helm 图表存储在 Bitbucket 存储库中。
pipeline {
agent any
stages {
stage('Download Helm Charts') {
steps {
sh "echo 'Downloading Helm Charts from Bitbucket repository...'"
git checkout http://192.168.1.30:7990/scm/jen/helm.git
// not sure do I need ot point the root folder of the Helm repository or only the single chart
}
}
stage('Test Kubernetes version') {
steps {
sh "echo 'Checking Kubernetes version..'"
// How to do remote test of kubernetes version
}
}
stage('Push Helm Charts to Kubernetes') {
steps {
sh "echo 'building..'"
// push here helm chart from Jenkins server to Kubernetes cluster
}
}
stage('Build Image') {
steps {
sh "echo 'building..'"
git checkout http://192.168.1.30:7990/scm/jen/spring-boot-microservice.git
// execute Java -jar ... and build docker image
}
}
stage('Push Image into Nexus registry') {
steps {
sh "echo 'building..'"
// push compiled docker image into Nexus repository
}
}
stage('Deploy Image from Nexus registry into Kubernetes') {
steps {
sh "echo 'building..'"
}
}
stage('Test'){
steps {
sh "echo 'Testing...'"
// implement a check here is it deployed sucessfully
}
}
}
}
我需要在这个 Jenkins 文件中添加什么配置才能从 bitbucket 下载 Heml 图表存储库并将配置应用到 Kubernetes 集群中？你能给我一个这样的 Jenkins 文件的例子吗？
假设您的 Pipeline 已位于 Helm 图表所在的 Bitbucket 存储库中。以下是存储库的示例结构。
\njenkins\n\xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 app1-charts\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 Chart.yaml\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 templates\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 app1.yml\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 _helpers.tpl\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 values.yaml\n\xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 Jenkinsfile\n根Jenkinsfile目录中将有一个简单的管道，如下所示。
jenkins\n\xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 app1-charts\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 Chart.yaml\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 templates\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x9c\xe2\x94\x80\xe2\x94\x80 app1.yml\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 _helpers.tpl\n\xe2\x94\x82\xc2\xa0\xc2\xa0 \xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 values.yaml\n\xe2\x94\x94\xe2\x94\x80\xe2\x94\x80 Jenkinsfile\n上述管道假设您在 Jenkins 代理中设置了 Helm。现在在 Jenkins 中，您可以创建一个新管道作业并选择选项Pipeline Script from SCM，然后提供 Bitbucket 配置。
确保Script Path设置为指向您的Jenkinsfile. 另外，请确保Lightweight checkout未选中。
添加配置后，这将克隆带有 Helm 图表的存储库，并在存储库中运行管道，该管道将执行 Helm 图表。
\n更新：检查 bitbucket 存储库的管道
\n检查以下管道示例。如果存储库是私有的，您可能必须生成具有必要权限的访问令牌才能签出存储库。
\npipeline {\n agent any\n stages {\n stage(\'Build1\') {\n steps { \n echo "Doing some build here if you need"\n }\n }\n \n stage(\'Applying helm charts\') {\n steps {\n echo "Running Helm"\n sh "helm upgrade --wait --timeout 60 --set image.tag=${SOME_INPUT} app1-name ./app1-charts"\n }\n }\n }\n}\n更新
\npipeline {\n agent any\n\n stages {\n stage(\'checkout\') {\n steps {\n echo \'Checking out code from bitbucket\'\n git(url: \'https://x-token-auth:REPO_ACCESS_TOKEN@bitbucket.org/ORG_NAME/your-repo.git\', branch: \'master\')\n sh """\n cd your-helm-directory\n helm install .............. Or whatever command you need\n """\n }\n }\n }\n}\n更新
\n这是如何列出图像的完整工作示例。
