我已经用jenkins指令建造了一个Jenkins码头工具:
docker run -u root --rm -d -p 8080:8080 -p 50000:50000 -v /root/.ssh/id_rsa:/root/.ssh/id_rsa -v jenkins-home:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkinsci/blueocean
它符合我的预期。
然后我设置了一个新的Pipeline作业,Jenkinsfile就像这样简单:
pipeline {
agent {
docker {
image 'maven:3-alpine'
args '-v /root/.m2:/root/.m2'
}
}
stages {
stage('Build') {
steps {
sh 'mvn -B -DskipTests clean package'
}
}
stage('Test') {
steps {
echo "Testing!"
}
}
stage('Deploy') {
steps {
sh "ssh docker@192.168.99.101 rm -rf /home/docker/wildfly_deployments/*"
sh "scp target/test-docker-app-1.0.war docker@192.168.99.101:/home/docker/wildfly_deployments/"
}
}
}
}
当我在“Deploy”阶段运行此作业时,它会显示此错误消息
[test-docker-app] Running shell script
+ ssh docker@192.168.99.101 rm -rf /home/docker/wildfly_deployments/*
/var/jenkins_home/workspace/test-docker-app@tmp/durable-4cd12dd8/script.sh: line 1: ssh: not found
script returned exit code 127
我确定Jenkins容器可以执行ssh和scp,因为我试图在Jenkins容器中运行相同的命令,我工作了。
你知道我在Jenkinsfile中的错误吗?请帮忙
感谢。
===============================
我在jenkinsfile中发现了这个问题,应该是:
pipeline {
agent any
stages {
stage('Build') {
agent {
docker {
image 'maven:3-alpine'
args '-v m2_repos:/root/.m2'
}
}
steps {
sh 'mvn -B -DskipTests clean package'
}
}
stage('Test') {
steps {
echo "Testing!"
}
}
stage('Deploy') {
steps {
sh "ssh docker@192.168.99.101 rm -rf /home/docker/wildfly_deployments/*"
sh "scp target/test-docker-app-1.0.war docker@192.168.99.101:/home/docker/wildfly_deployments/"
/*sh 'bash ./deploy.sh'*/
}
}
}
}
答案 0 :(得分:0)
对我来说,理解的关键是名为“ Master”的构建执行器是blueocean jenkinsci FROM jenkinsci / blueocean映像的运行时“ Agent”上下文
在Jenkinsfile中,代理{标签'master'}表示在Master上运行步骤,代理{标签'Dockerfile'}表示在项目docker容器中运行步骤。
您需要一个多代理程序管道,因此从agent none
开始,并在针对其代理程序环境的每个阶段添加一个代理程序。在这种情况下,agent { label 'master' }
从jenkinsci/blueocean
容器
太明显了,任何人都无法解释...!
您将需要SSH代理插件来创建证书,并复制一个私密ssh密钥。它将为您提供一个ID,供您在Jenkinsfile DSL脚本中使用
pipeline {
agent none
stages {
stage('Hello Docker') {
agent { dockerfile {filename 'Dockerfile'}}
steps {
echo 'Hello Docker'
}
}
stage('Make useful SSH connections') {
agent { label 'master' }
steps{
//Your in the in Master Container
sh 'hostname'
//In this working directory
sh 'pwd'
//You provide SSH credentails via the SSHagent
sshagent(credentials : ['<ID OF THE SSH AGENT CREDENTIAL>']) {
//Connect to hostip/s with ssh, run scripts, go wild!
sh 'ssh -o StrictHostKeyChecking=no user@hostip uptime'
//and SCP
sh 'scp ./source/filename user@hostip:/remotehost/target
}
}
}
Jenkins节点由代理标签cool :)
