Jenkins 与 skaffold 示例

概述

准备操作

配置 webhook

配置 Jenkins Pipeline 自动 clone 代码并获取 Jenkinsfile 文件

代码示例

Jenkinsfile

skaffold.yaml

main.go

Dockerfile

k8s-pod.yaml

运行结果：

准备操作

配置 webhook

从 jenkins 项目中，获取 webhook 的 URL 和 TOKEN，填到 gitlab 指定项目的 webhooks 中。

Jenkins 项目的 TOKEN 需要在构建触发器栏目中，点击 高级，然后点击 Generate 来生成。

在 GitLab 中填写 URL 和 TOKEN ，并点击 Add Webhook 即可，添加完成后，可以在最下方点击 Test 来测试连通性。

配置 Jenkins Pipeline 自动 clone 代码并获取 Jenkinsfile 文件

使用如下配置，开始构建前，让 Jenkins 自动获取代码仓库中的 Jenkinsfile 文件，并根据该文件执行 pipeline

在流水线类型的任务中，进行如下配置

代码示例

Jenkinsfile

pipeline {
  agent any
  stages {
    stage('build') {
      steps {
        sh 'export TAG=1.0 && skaffold run'
      }
    }
  }
}

skaffold.yaml

apiVersion: skaffold/v2alpha1
kind: Config
build:
  artifacts:
  - image: 172.38.40.180/test/pipeline-test
  tagPolicy:
    envTemplate:
      template: "{{.TAG}}"
  local:
    push: true
deploy:
  kubectl:
    manifests:
      - k8s-*

main.go

package main
import (
  "fmt"
  "time"
)
func main() {
  for {
    fmt.Println("Hello Jenkins,Skafflod!")
    time.Sleep(time.Second * 5)
  }
}

Dockerfile

FROM golang:1.14.7
WORKDIR /src
COPY main.go .
RUN go build main.go
FROM ubuntu
COPY --from=0 /src/main .
CMD ["./main"]

k8s-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: getting-started
spec:
  containers:
  - name: getting-started
    image: 172.38.40.180/test/pipeline-test:1.0

运行结果：
