以下代码段是Cypress提供的示例，Cypress是我正在使用的Javascript测试框架。这是Github页面的link。
pipeline {
agent {
// this image provides everything needed to run Cypress
docker {
image 'cypress/base:10'
}
}
stages {
// first stage installs node dependencies and Cypress binary
stage('build') {
steps {
// there a few default environment variables on Jenkins
// on local Jenkins machine (assuming port 8080) see
// http://localhost:8080/pipeline-syntax/globals#env
echo "Running build ${env.BUILD_ID} on ${env.JENKINS_URL}"
sh 'npm ci'
sh 'npm run cy:verify'
}
}
stage('start local server') {
steps {
// start local server in the background
// we will shut it down in "post" command block
sh 'nohup npm run start:ci &'
}
}
// this stage runs end-to-end tests, and each agent uses the workspace
// from the previous stage
stage('cypress parallel tests') {
environment {
// we will be recording test results and video on Cypress dashboard
// to record we need to set an environment variable
// we can load the record key variable from credentials store
// see https://jenkins.io/doc/book/using/using-credentials/
CYPRESS_RECORD_KEY = credentials('cypress-example-kitchensink-record-key')
// because parallel steps share the workspace they might race to delete
// screenshots and videos folders. Tell Cypress not to delete these folders
CYPRESS_trashAssetsBeforeRuns = 'false'
}
// https://jenkins.io/doc/book/pipeline/syntax/#parallel
parallel {
// start several test jobs in parallel, and they all
// will use Cypress Dashboard to load balance any found spec files
stage('tester A') {
steps {
echo "Running build ${env.BUILD_ID}"
sh "npm run e2e:record:parallel"
}
}
// second tester runs the same command
stage('tester B') {
steps {
echo "Running build ${env.BUILD_ID}"
sh "npm run e2e:record:parallel"
}
}
}
}
}
post {
// shutdown the server running in the background
always {
echo 'Stopping local server'
sh 'pkill -f http-server'
}
}
}
我的目标是要有一个与上述非常相似的Jenkinsfile，因为我想进行并行的Cypress测试，如上面的代码片段所示。在上面的示例中，Jenkins代理只是官方的 Cypress Docker镜像
cypress/base:10。 agent {
// this image provides everything needed to run Cypress
docker {
image 'cypress/base:10'
}
}
但是，要使用我自己的数据库运行所有测试，我需要启动两个单独的Docker容器。一个容器包含我的Web应用程序的前端部分，另一个容器包含我的Web应用程序的后端部分。
以下是我的前端容器的Dockerfile，该文件位于
my-app/docker/combined/Dockerfile中。FROM cypress/included:3.4.1
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 5000
RUN npm install -g history-server nodemon
RUN npm run build-test
EXPOSE 8080
以下是我的后端容器的Dockerfile，该文件位于
my-app/docker/db/Dockerfile中。它所做的就是将一些本地数据复制到Docker容器中，然后使用该数据初始化我的MongoDB数据库。FROM mongo:3.6.14-xenial
COPY ./dump/ /tmp/dump/
COPY mongo_restore.sh /docker-entrypoint-initdb.d/
RUN chmod 777 /docker-entrypoint-initdb.d/mongo_restore.sh
通常，我将使用
docker-compose和以下docker-compose.yml文件启动这两个容器。如您所见，称为“combined”的前端容器取决于称为“db”的后端容器。version: '3'
services:
db:
build:
context: .
dockerfile: ./docker/db/Dockerfile
container_name: b-db
restart: unless-stopped
volumes:
- dbdata:/data/db
ports:
- "27017:27017"
networks:
- app-network
combined:
build:
context: .
dockerfile: ./docker/combined/Dockerfile
container_name: b-combined
restart: unless-stopped
env_file: .env
ports:
- "5000:5000"
- "8080:8080"
networks:
- app-network
depends_on:
- db
以下是我将使用的docker-compose命令。
docker-compose up --build
我希望我的Jenkins代理成为
combined容器；但是，我需要将combined容器连接到需要旋转的db容器。我的问题是，如何在 Jenkins 管道中实现这一目标？我读过this documentation;但是，它没有提及使用多个Dockerfile创建Jenkins代理的任何内容。这样的事情是否可能发生，有人可以告诉我实现我的目标的Jenkinsfile应该是什么样吗？
