Jenkins / JENKINS-58497 Jenkins picks a random agent if agent is 'null' Issue Type: Bug Assignee: Unassigned Attachments: image-2019-07-15-11-32-00-541.png Components: core Created: 2019-07-15 15:32 Priority: Minor Reporter: hemil patel Jenkins picks a random agent if agent is 'null' How to reproduce Create a pipeline job with following script  pipeline { agent none stages { stage ('This stage should not run anywhere.') { agent { label env.NODE_THAT_DOES_NOT_EXIST } steps { echo "Agent is : " + env.NODE_THAT_DOES_NOT_EXIST echo 'Test' } } } } Results The way I expect this to work is if the node does not exist, the Jenkins pipeline should fail saying the "The node does not exist" instead of picking up a random agent from available agents. Acceptance criteria Fail the pipeline if the agent is null . Add Comment

Re: Jenkins picks a random agent if agent is 'null' Looks like "As designed", will defer to the Pipeline team. CC Liam Newman

Re: Jenkins picks a random agent if agent is 'null'

Hmm, If this is as designed, I can see this being potentially destructive. For eg.

pipeline { agent none stages { stage ('This stage should not run anywhere.') { agent { label env.NODE_THAT_DOES_NOT_EXIST } steps { echo "Agent is : "

+ env.NODE_THAT_DOES_NOT_EXIST echo 'Do a destructive action' killServer() } } } } def killServer() { //kill server code here } For such a small mistake, user should not have to suffer potentially catastrophic damage.
