I'm setting up a Jenkins pipeline with Kubernetes, there is an option to set environment variables for a container in containerTemplate. Is there some option to override those values in container i.e.:
container(
name: 'my-container',
envVars: [
envVar(key: $KEY, value: $VALUE)
]) {
...
}
because some variables are derived during build stages and cannot be set up in podTemplate. The example above unfortunately does not work.
Note that as of this writing as per the docs:
The container statement allows to execute commands directly into each container. This feature is considered ALPHA as there are still some problems with concurrent execution and pipeline resumption
I believe there is not an option. However, you can try setting the variables in the sh command. For example:
def label = "mypod-${UUID.randomUUID().toString()}"
podTemplate(label: label, containers: [
containerTemplate(name: 'maven', image: 'maven:3.3.9-jdk-8-alpine', ttyEnabled: true, command: 'cat'),
containerTemplate(name: 'golang', image: 'golang:1.8.0', ttyEnabled: true, command: 'cat')
]) {
node(label) {
stage('Get a Maven project') {
git 'https://github.com/jenkinsci/kubernetes-plugin.git'
container('maven') {
stage('Build a Maven project') {
sh 'MYENV1=value1 MYEVN2=value2 mvn -B clean install'
}
}
}
stage('Get a Golang project') {
git url: 'https://github.com/hashicorp/terraform.git'
container('golang') {
stage('Build a Go project') {
sh """
mkdir -p /go/src/github.com/hashicorp
ln -s `pwd` /go/src/github.com/hashicorp/terraform
MYENV1=value1 MYEVN2=value2 cd /go/src/github.com/hashicorp/terraform && make core-dev
"""
}
}
}
}
}
