Lionel Orellana created an issue   Jenkins / JENKINS-42184 All pod templates in the pipeline are assumed to be nested Issue Type: Bug Assignee: Carlos Sanchez Components: kubernetes-plugin Created: 2017/Feb/20 5:51 AM Environment: Jenkins v2.44 Kubernetes Plugin v0.10 Openshift v1.3.0 Priority: Major Reporter: Lionel Orellana Creating multiple podTemplates with different labels allows you to create pods in parallel. However the plugin treats all podTemplates in a Run as nested even when they are not. Every podTemplate in the pipeline effectively inherits from previously declared templates. Consider the following pipeline. stage ('Compile') { podTemplate(label: 'node-0', containers: [containerTemplate(name: 'maven', ...)]) { node('node-0') { container('maven') { sleep(1) } } } } stage ('Tests') { parallel ( "A": { podTemplate(label: 'node-a', containers: [containerTemplate(name: 'maven', ...)])) { node('node-a') { container('maven') { sleep (15) } } } }, "B": { podTemplate(label: 'node-b', containers: [containerTemplate(name: 'maven', ...)])) { node('node-b') { container('maven') { sleep (15) } } } } ) } This creates a template for node-a that inherits from node-0 and a template for node-b that inherits from both node-a and node-0. Keep adding pod templates and they keep nesting in weird way. Depending on the nesting rules and the names used on each template some containers get created while others don't. The behaviour becomes quite erratic. e.g. I'm seeing the HOME var of one container being set to the start-up command of another (HOME='/bin/sh -c'). In any case the intention of the pipeline developer here cleary isn't to nest temmplates. The hacky workaround to stop this is to clear all previously stacked template names from the Run before creating a new template. Call this function before any occurrence of podTemplate: @NonCPS def clearTemplateNames() { def r = script.currentBuild.rawBuild def action = ""> if(action) { action.names.clear() } } Add Comment   This message was sent by Atlassian JIRA (v7.1.7#71011-sha1:2526d7c) -- You received this message because you are subscribed to the Google Groups "Jenkins Issues" group.
