**Global environments on jenkins should be outside the pipeline** ,can be initialized/used inside the scripts, and of course known by all scopes inside the pipeline:
**example**:
def internal_ip
pipeline {
agent { node { label "test" } }
stages {
stage('init') {
steps {
script {
def x
if(env.onHold.toBoolean() == true){
x=1
}else{
x=2
}
internal_ip = sh (
script: "echo 192.168.0.${x}",
returnStdout: true
).trim()
}
}
}
stage('test') {
steps {
script {
echo "my internal ip is: ${internal_ip}"
}
}
}
}
}
}
Just out of curiosity I've taken a look at what happens under the hood, and I've used [dtruss/strace][1] on each test.
