Jenkins / JENKINS-49581 Pipeline with syntax error hung forever Issue Type: Bug Assignee: Carlos Sanchez Components: kubernetes-plugin Created: 2018-02-15 15:41 Environment: Jenkins 2.101 Priority: Minor Reporter: Witold Konior Hi, Take this example: podTemplate( label: 'postgres', containers: [ containerTemplate( name: 'postgres', image: 'postgres/latest', privileged: false, alwaysPullImage: true, ) ], node('validate'){ container('datamodel') { stage("Pull") { checkout scm } } } ) In my opinion there is syntax error here, didn't find any reference to `node` field in `podTemplate`. However this will wait forever for `pod` in k8s cluster while it's never created. After changing this into proper syntax, it works ofc.   Add Comment

Change By: Witold Konior Hi, Take this example: {code:java}

podTemplate(     label: 'postgres',     containers: [         containerTemplate(             name: 'postgres',             image: 'postgres/latest',             privileged: false,             alwaysPullImage: true,         )     ],

node(' validate postgres '){         container(' datamodel postgres ') {

stage("Pull") {                 checkout scm             }         }     } )

{code}

In my opinion there is syntax error here, didn't find any reference to `node` field in `podTemplate`. However this will wait forever for `pod` in k8s cluster while it's never created. After changing this into proper syntax, it works ofc.

Hi, Take this example: {code:java} podTemplate(     label: 'postgres',     containers: [         containerTemplate(             name: 'postgres',             image: 'postgres/latest',             privileged: false,             alwaysPullImage: true,         )     ],

node('postgres'){         container('postgres') {

stage("Pull") {                 checkout scm             }         }     } ) {code}

In my opinion there is syntax error here, didn't find any reference to `node` field in `podTemplate`. However this will wait forever for `pod` in k8s cluster while it's never created. After changing this into proper syntax, it works ofc.

And this is what I see from console logs: !image-2018-02-15-16-44-13-193.png! Seems like vary common info, while it's waiting for `POD` creation.

Re: Pipeline with syntax error hung forever can you provide jenkins logs? https://github.com/jenkinsci/kubernetes-plugin/#debugging

Re: Pipeline with syntax error hung forever

I'm afraid that there is no logs at all. Other piplines generate a lot of output to  this logger `org.csanchez.jenkins.plugins.kubernetes` however not UUT one. In "main" logger I get notification only after I abort job otherwise it's no mentioned , but I think it's not relevant, or ?

Re: Pipeline with syntax error hung forever ok, so it's a pipeline issue, not k8s plugin

Actually, this'd be in kubernetes-plugin - something about podTemplate must be executing that node block. Change By: Andrew Bayer Component/s: kubernetes-plugin Component/s: pipeline

Re: Pipeline with syntax error hung forever What I think is happening is the following. Given the lazy evaluation of actual arguments intrinsic to Groovy, the groovy interpreter first tries to obtain all the actual arguments before calling the function. As part of that process it runs the node() step. Since podTemplate(label: 'postgres', ...) hasn't been called yet, there is no node with that label, and the node() step blocks indefinitely trying to get hold of such a node. Notice the interpreter can't detect the wrong argument type in the call to podTemplate() since it first needs to evaluate the node() step. This kind of issues are catched by the compiler in a type-safe language. If the node() step gave up and returned, the interpreter would catch the wrong argument type and the call to podTemplate() would fail.
