Jenkins ver. 2.60.1 (running in container on kubernetes)
Kubernetes Plugin ver. 0.11 (https://github.com/jenkinsci/kubernetes-plugin)
Pipeline test:
podTemplate(
label: 'mypod',
volumes: [
persistentVolumeClaim(claimName: 'nfs-maven', mountPath: '/mnt/', readOnly: false)],
envVars: [
containerEnvVar(key: 'FOO', value: 'BAR'),
],
containers: [
containerTemplate(name: 'golang',
image: 'golang',
ttyEnabled: true,
command: 'cat',
)]
)
{
node('mypod') {
stage('test env') {
container('golang') {
stage('build') {
sh 'echo $FOO'
sh 'sleep 3600'
}
}
}
}
}
The vars are not passed into the containers. The echo echoes nothing. echo $FOO or echo \$FOO I have tried on the pod level and container level.
When i describe the created pod i only get the following environment vars:

HOME: /home/jenkins I'm guessing a little, but I don't think envVars in podTemplate is fully functional. Like you, I haven't had luck with the podTemplate, but I've had no problem using envVars at the containerTemplate level. The easy fix is to add your envVars there instead.
podTemplate(
label: 'mypod',
volumes: [
persistentVolumeClaim(claimName: 'nfs-maven', mountPath: '/mnt/', readOnly: false)],
containers: [
containerTemplate(
name: 'golang',
image: 'golang',
ttyEnabled: true,
command: 'cat',
envVars: [containerEnvVar(key: 'FOO', value: 'BAR')]
)
]
)
{
node('mypod') {
stage('test env') {
container('golang') {
stage('build') {
sh 'echo $FOO'
sh 'sleep 3600'
}
}
}
}
}
Upgrading the kubernetes-plugin to 0.12 (29/07/2017) and restarting jenkins has fixed the issue!
