Jenkins 2.414.2
Kubernetes plugin 4029.v5712230ccb_f8
Kubernetes Client API Plugin 6.8.1-224.vd388fca_4db_3b_
Deadlock seems to happen when a jenkins kubernetes agent is trying to be created but it cannot due to some error. In this case having wrongly configured a container. Example:
podTemplate(containers: [
containerTemplate(name: 'maven', image: 'wrong_name:3.0.0', command: 'sleep', args: '99'),
]) {
retry(count: 100, conditions: [kubernetesAgent(), nonresumable()]) {
node(POD_LABEL) {
stage('Get a Maven project') {
container('maven') {
stage('Hello')
}
}
}
}
}
"wrong_name" image does not exists and then it retries 100 times.
While this pod is being created, when going to manage/configure and pushing save button; configuration is not saved and an error 504 appears in browser.
