Jenkins ver. 2.107.3 with kubernetes-plugin
Description
Simplified version of my declarative pipeline looks like this:
pipeline {
agent {
kubernetes {
cloud 'kube-cloud'
label 'kube'
yaml """
apiVersion: v1
kind: Pod
metadata:
name: kube
spec:
containers:
- name: jnlp
image: jenkins/jnlp-slave
"""
}
}
stages {
stage('step-in-kubernetes') {
steps {
sh 'echo inKubernetes'
}
}
stage('step-in-agent') {
agent {
label 'agentX'
}
steps {
sh 'echo inAgent'
}
}
}
}
In this case pipeline fails on stage 'step-in-agent' as following:
Running in Durability level: MAX_SURVIVABILITY

All nodes of label ‘kube’ are offline

In my real pipeline, I must run a few steps in parallel on kubernetes containers, and after this I must run some steps on other agent which cannot be in kubernetes container. I know that it is possible to do something like this in scripted pipeline, but it is possible to achieve this in declarative pipeline ?

same here. I wanted to have a default k8s agent, and in the sub-stage I want to allocate a node for isolating the tests. However, it shows "can not cd into {workspace}" error.

added a comment - We are also suffering this issue on jenkins 2.176.2 with kubernetes plugin 1.18.1

added a comment - We are also suffering this issue on jenkins 2.176.2 with kubernetes plugin 1.18.1 I don't think it can be fixed by the plugin. It is just a syntax limitation which can't be overcome.
I think this is a combination of a limitation in the kubernetes plugin (you can't run a node block inside a container block) and a limitation in Declarative (per-stage agents run within the top-level agent block). You may want to investigate sequential stages (https://jenkins.io/blog/2018/07/02/whats-new-declarative-piepline-13x-sequential-stages/) - you could have a top level agent none, then a parent stage with the kubernetes agent and a stages block of all the stages that need to run on that kubernetes agent, and finally, outside of that parent stage, the stage that needs to run on a different agent.
