[英]To pass variables set in jenkins pipeline to shell script
I want to send few parameters to one of my shell scripts written in linux server from a jenkins job.我想从 jenkins 作业向我在 linux 服务器中编写的 shell 脚本之一发送一些参数。 Below is my jenkins pipeline job:
下面是我的 jenkins 管道作业:
def MY_VAR
def BUILD_NUMBER
pipeline {
agent any
stages {
stage('Stage One') {
steps {
script {
BUILD_NUMBER={currentBuild.number}
MY_VAR ='abc'
}
}
}
stage('Stage Two') {
steps {
sh '''
cd /scripts/
./my_scripts.sh $BUILD_NUMBER $MY_VAR'''
}
}
}
}
Here I am able to send the value of BUILD_NUMBER
but not of MY_VAR
.在这里,我可以发送
BUILD_NUMBER
的值,但不能发送MY_VAR
的值。 It seems to me that since MY_VAR
is set into pipeline that is why it is happening.在我看来,由于
MY_VAR
被设置为管道,这就是它发生的原因。 Can anybody please help with the solution有人可以帮忙解决吗
If you want to interpolate $MY_VAR
when executing sh
step, you need to replace single quotes with the double-quotes.如果要在执行
sh
步骤时插入$MY_VAR
,则需要将单引号替换为双引号。
def MY_VAR
def BUILD_NUMBER
pipeline {
agent any
stages {
stage('Stage One') {
steps {
script {
BUILD_NUMBER={currentBuild.number}
MY_VAR ='abc'
}
}
}
stage('Stage Two') {
steps {
sh """
cd /scripts/
./my_scripts.sh $BUILD_NUMBER $MY_VAR"""
}
}
}
}
The $BUILD_NUMBER
worked, because pipeline exposes env.BUILD_NUMBER
and this variable can be accessed inside the shell step as bash's $BUILD_NUMBER
env variable. $BUILD_NUMBER
起作用了,因为管道公开env.BUILD_NUMBER
,并且可以在 shell 步骤中作为 bash 的$BUILD_NUMBER
env 变量访问此变量。 Alternatively, you could set MY_VAR
as an environment variable and keep single quotes in the sh
step.或者,您可以将
MY_VAR
设置为环境变量并在sh
步骤中保留单引号。 Something like this should do the trick:这样的事情应该可以解决问题:
pipeline {
agent any
stages {
stage('Stage One') {
steps {
script {
//you can remove BUILD_NUMBER assignment - env.BUILD_NUMBER is already created.
//BUILD_NUMBER={currentBuild.number}
env.MY_VAR ='abc'
}
}
}
stage('Stage Two') {
steps {
sh '''
cd /scripts/
./my_scripts.sh $BUILD_NUMBER $MY_VAR'''
}
}
}
}
