添加凭证

Pipeline script

pipeline {

agent any

stages {

stage('withCredentials 使用凭证') {

steps {

withCredentials([usernamePassword(credentialsId: 'DockerServer', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {

// available as an env variable, but will be masked if you try to print it out any which way

// note: single quotes prevent Groovy interpolation; expansion is by Bourne Shell, which is what you want

bat 'echo ${USERNAME}' //Linux 下 sh 'echo $USERNAME'，TODO Windows 上怎么写，

// also available as a Groovy variable

echo USERNAME

// or inside double quotes for string interpolation

echo "username is $USERNAME"

}

echo 'Credentials SUCCESS'

}

}

//指定 Docker 服务器节点。用于编译、上传镜像，指定K8S节点，用于升级程序

stage('指定节点中使用凭证') {

agent { label 'DockerAgent' }

steps {

withCredentials([usernamePassword(credentialsId: 'DockerServer', usernameVariable: 'USERNAME', passwordVariable: 'PASSWORD')]) {

sh 'docker --version'

sh "echo 'docker login -u ${USERNAME} -p ${PASSWORD} image_url'"

}

echo 'Credentials SUCCESS'

}

}

}

}
