Environment:Jenkins 2.85
Kubernetes plugin 1.1 / 1.1.2
We updated the kubernetes plugin to 1.1 and Jenkins to 2.85 yesterday.
When you create the pod with a node block inside a podTemplate, it will create 2 pods now instead of 1. The second one seems to be create 10 seconds after the first 1 is created.
debian-lfxb0-8s18k 2/2 Running 0 5s
debian-lfxb0-d53mq 2/2 Running 0 15s
Simplified test case
podTemplate(
name: "debian",
label: "debian",
instanceCap: 1,
containers: [
containerTemplate(
name: 'debian',
image: "debian",
ttyEnabled: true,
command: "cat"
)
]
) {
node("debian") {
sleep 99999
}
}
Edit: It seems to be some change in 1.1, kubernetes plugin 1.0 seems to only start one pod.
