我是一名有用的助手,可以为您进行文本翻译。
我使用来自Docker容器的Jenkins。我想在Jenkins流水线中构建Docker镜像,但是该容器中不存在Docker(即Jenkins所在容器中没有安装Docker)。
Jenkins容器由Docker Compose部署,yml文件如下:
version: "3.3"
services:
jenkins:
image: jenkins:alpine
ports:
- 8085:8080
volumes:
- ./FOR_JENKINS:/var/jenkins_home
我们可以在Jenkins管道中构建Docker镜像。我们是否可以使用Docker部署某些Docker容器,并仅在构建Docker镜像时使用它们?还是其他方法?您如何处理这些问题? 编辑: 感谢@VonC,我检查了您的信息,但是......“权限被拒绝”。
Docker Compose文件:
version: "3.3"
services:
jenkins:
image: jenkins:alpine
ports:
- 8085:8080
volumes:
- ./FOR_JENKINS:/var/jenkins_home
# - /var/run/docker.sock:/var/run/docker.sock:rw
- /var/run:/var/run:rw
Jenkinsfile:
pipeline {
agent any
stages {
stage('Build') {
steps {
echo "Compiling..."
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt compile"
}
}
/*stage('Unit Test') {
steps {
echo "Testing..."
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt coverage 'test-only * -- -F 4'"
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt coverageReport"
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt scalastyle || true"
}
}*/
stage('DockerPublish') {
steps {
echo "Docker Stage ..."
// Generate Jenkinsfile and prepare the artifact files.
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt docker:stage"
echo "Docker Build-2 ..."
// Run the Docker tool to build the image
script {
docker.withTool('docker') {
echo "D1- ..."
//withDockerServer([credentialsId: "AWS-Jenkins-Build-Slave", uri: "tcp://192.168.0.29:2376"]) {
echo "D2- ..."
sh "printenv"
echo "D3- ..."
//sh "docker images"
echo "D4- ..."
docker.build('my-app:latest', 'target/docker/stage').inside("--volume=/var/run/docker.sock:/var/run/docker.sock")
echo "D5- ..."
//base.push("tmp-fromjenkins")
//}
}
}
}
}
}
}
结果:
[job1] Running shell script
+ docker build -t my-app:latest target/docker/stage
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.29/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&cpuquota=0&cpusetcpus=&cpusetmems=&cpushares=0&dockerfile=Dockerfile&labels=%7B%7D&memory=0&memswap=0&networkmode=default&rm=1&shmsize=0&t=my-app%3Alatest&target=&ulimits=null: dial unix /var/run/docker.sock: connect: permission denied
script returned exit code 1
编辑: "权限被拒绝" 的最后一个问题已经得到解决,方法如下:
>>sudo chmod 0777 /var/run/docker.sock

我的决心:
我在Jenkinsfile中添加了一些步骤,结果得到了:
pipeline {
agent any
//def app
stages {
stage('Build') {
steps {
echo "Compiling..."
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt compile"
}
}
stage('DockerPublish') {
steps {
echo "Docker Stage ..."
// Generate Jenkinsfile and prepare the artifact files.
sh "${tool name: 'sbt', type: 'org.jvnet.hudson.plugins.SbtPluginBuilder$SbtInstallation'}/bin/sbt docker:stage"
echo "Docker Build ..."
// Run the Docker tool to build the image
script {
docker.withTool('docker') {
echo "Environment:"
sh "printenv"
app = docker.build('ivanbuh/myservice:latest', 'target/docker/stage')
echo "Push to Docker repository ..."
docker.withRegistry('https://registry.hub.docker.com', 'docker-hub-credentials') {
app.push("${env.BUILD_NUMBER}")
app.push("latest")
}
echo "Complated ..."
}
}
