Kubernetes plugin declarative pipeline can't use readFile to read yaml file

Issue Type:	Bug
Assignee:	Carlos Sanchez
Components:	kubernetes-plugin
Created:	2018-05-10 22:02
Priority:	Minor
Reporter:	Kevin Carrasco

Using the following settings declarative pipeline:

 
                                                                pipeline {
    agent {
        kubernetes {
            cloud 'OpenShift'
            label 'jenkins-agent-pod'
            yaml readFile('k8s-podspec.yaml')
        }
    }
... 
                                                            

Results in the following error from Jenkins:

 
                                                                Running in Durability level: MAX_SURVIVABILITY
[Pipeline] readFile
Required context class hudson.FilePath is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node
[Pipeline] End of Pipeline

Re: Kubernetes plugin declarative pipeline can't use readFile to read yaml file

Not a K8s plugin defect IMHO. In Declarative the workspace is not mapped before creating the first agent, hence readFile() cannot work in this section AFAIK

From where do you expect to read it? From master? or from the repo?

Re: Kubernetes plugin declarative pipeline can't use readFile to read yaml file

Oleg Nenashev is correct - we should probably add something to the kubernetes plugin's Declarative agent setup for doing a readTrusted of a YAML file for this sort of use case.

Re: Kubernetes plugin declarative pipeline can't use readFile to read yaml file

Oleg Nenashev I expect to read k8s-podspec.yaml from the repository.

Re: Kubernetes plugin declarative pipeline can't use readFile to read yaml file

[~oleg_nenashev] I expect to read k8s-podspec.yaml from the repository. We would like the yaml file to be part of the source code on a separate file. For now we're including the yaml contents in the Jenkinsfile.
