We have a jenkins master-slave architecture and using the Kubernetes Jenkins plugin. The podTemplate looks as below
podTemplate(label: 'builder-pod', cloud: 'kubernetes', containers: [
containerTemplate(
name: 'jnlp',
image: "${artifact_repo}/jenkins-slave",
ttyEnabled: true,
privileged: false,
alwaysPullImage: false,
workingDir: '/var/jenkins_home',
resourceRequestCpu: '1000m',
resourceRequestMemory: '1Gi',
resourceLimitMemory: '1.1Gi',
)
], volumes: [hostPathVolume(mountPath: '/var/run', hostPath: '/var/run')], namespace: 'jenkins') { //podtemplate
node('builder-pod') {
container('jnlp') {For whatever reason the builder-pod is being created in default namespace instead of the jenkins namespace
Any idea what could be wrong? Thanks in advance.
You could always force the namespace by including that in your container definition:
containerTemplate(
name: 'jnlp',
namespace: 'jenkins',
image: "${artifact_repo}/jenkins-slave",
ttyEnabled: true,
privileged: false,
alwaysPullImage: false,
workingDir: '/var/jenkins_home',
resourceRequestCpu: '1000m',
resourceRequestMemory: '1Gi',
resourceLimitMemory: '1.1Gi',
)
As to why it isn't being loaded into the proper namespace, do you have a default kubernetes plugin config setup anywhere? There are settings for both the general namespace target and individual container template namespace targets. If you have neither, the above solution to set the namespace value may be the only way
You need to check on the Jenkins admin interface the Kubernetes plugin configuration, you are able to override some parameters from de UI.
check the name with:
kubectl config get-contextsAnd then change the context namespace before deploying your pod
kubectl config <NAME> set-context --namespace=jenkins
