White screen when downloading plugins

[Peter Berghold]

Hi folks,

I saw mention of a "white screen of death" with some issues in the JIRA but
I'm not 100% sure this is related.

I selected a few plugins to install across the internet and when I
requested the download start I got "this page is not working" from the
browser.  I use Chrome both at home and work and my personal Jenkins server
is seeing the problem and one of the newest instances at work (version
2.164.2) are both displaying this behavior.

1) is there a good workaround to let me download and install plugins
(automating with Puppet would be the best!)

2) is this a known problem

3) is there a viable workaround to get the page "working" again?

Re: Anyone using Jenkins as a job scheduler?

[Peter Berghold]

I actually use Jenkins to perform a backup of my Git (privately hosted)
repository and ship an archive off to AWS S3.

Re: Class paths for Jenkins?

[Peter Berghold]

was kinda hoping I could solve this without the overhead of a module.  And
no there isn't as far as I can tell a module that does what I need to do.

Class paths for Jenkins?

[Peter Berghold]

Following up on a silly question from the other day I have another silly
question. Where does Jenkins look for jar files to resolve classes and
packages?

I've started writing a Java library that I want to access from a pipeline
and Jenkins can't seem to find it in spite of it being deployed to
/usr/share/java where other Java applications find their jars.

Any pointers are appreciated.

Adding java libraries to jenkins

[Peter Berghold]

How would I go about adding java libraries to jenkins?  I may not be
voicing what I'm trying to do very well so I'll go into a little detail.

I'd like to set up a library of beans such as one reflective of the
contents of a list of s3 files with the creation date, size and filename as
a structure.

Is this even possible?

Re: Shared groovy library frustration

[Peter Berghold]

Not sure if this is really what fixed the problem but here goes:

Destroyed the Docker instance running my Jenkins installation and rebuilt
it using LTS instead of the "latest and greatest bleeding edge" version.
Docker is a good thing that way. :-)

Now have a stripped down version and my simple shared library now works.
I'll move on to more complicated ones next.  Is this a problem with the
version I was using  dunno.

Re: Shared groovy library frustration

[Peter Berghold]

Interestingly enough on a Jenkins server i manage where I have working
shared libraries (multiple) I don't use the @Library form at all.  I tried
it on this other Jenkins server (the one I'm trying to *get* working) and
it didn't work.

In my first attempt I simply used:

@Library('lib3') _

which I saw in this documentation:
https://jenkins.io/doc/book/pipeline/shared-libraries/

that yielded me the following errors

ERROR: No version specified for library lib3
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: Loading libraries failed


OK fine,  I'll add a version to it which according to the cited page
above can be a branch and "master" is certainly a branch.


@Library('lib3@master') _


Using that gave me more errors

So what I'm wondering at this point, is there a plugin I'm missing?
What plugins are necessary to run Groovy pipelines including shared
libraries?


I'm stumped here... and grasping at straws.

Shared groovy library frustration

[Peter Berghold]

Here is a tree of a very simple "library" I set up:

├── build.xml
├── manifest.mf
├── nbproject
│   ├── build-impl.xml
│   ├── genfiles.properties
│   ├── groovy-build.xml
│   ├── private
│   │   ├── config.properties
│   │   ├── private.properties
│   │   └── private.xml
│   ├── project.properties
│   └── project.xml
└── src
├── net
│   └── berghold
│   └── MainTest.groovy
└── SimpleGroovyScript.groovy


Most important of which is under "src" with the class MainTest

Here is the class itself:

/*
 * To change this license header, choose License Headers in Project
Properties.
 * To change this template file, choose Tools | Templates
 * and open the template in the editor.
 */

package net.berghold

/**
 *
 * @author peter
 */
class MainTest implements Serializable {
def Object context

def void runme(){
context.sh('echo foobar')
}
}

so far nothing earth shattering.  I've set up this shared library in the
main Jenkins setup menu.   Should be groovy so far  but it isn't

Here is a simple pipeline I set up to test this:

import net.berghold.MainTest

node('master'){
step('run test'){
def MainTest mt = new MainTest(context: this)

mt.runme()
}
}

When I try to "build" this I get the following error to the console:

Running in Durability level: MAX_SURVIVABILITY
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 1: unable to resolve class net.berghold.MainTest
 @ line 1, column 1.
   import net.berghold.MainTest
   ^

1 error


to me that implies the library is not being loaded for reasons I just don't
get.

Things I tried:

I actually told it to implicitly load this library but it now complains
that it needs a version.  I told it "master" and it claims it can't find
that version.   I tried */master refs/master and a few other things I know
exist and the error came back that it could not validate the version with a
null pointer error under the details.

Has this functionality been broken?

Running Jenkins 2.147.   This all used to work.  This example is a pared
down version and the original shared libs that worked no longer work and
I'm a bit concerned.

Load balanced Jenkins?

[Peter Berghold]

I've been messing about a bit with Docker on Digital Ocean and was going to
branch next onto  Docker Swarm stuff.  I was wondering about deploying
Jenkins into a swarm and using a load balancer to switch between instances.

Is anybody aware of way of having multiple instances of Jenkins using the
same configurations other than possibly using slaves?

In other words it in my mind would be kinda useful if I logged into
"jenkins.some.domain" and let the load balancer direct my request between
multiple instances and have them look the same.

Templating inside a Groovy pipeline?

[Peter Berghold]

Is there a text templating solution that *works* inside a Groovy pipeline?

I tried both SimpleTemplate and StreamingTemplate and both error out with
an exception somewhere in the bowels of the class.  Am perhaps stuck with
using a callout to a Perl script to get this to work?

Security Access Violation?

It is rejecting access to a class constructor that doesn't look a
whole lot different than others.

(Pipelines) String split; why isn't this working?

[Peter Berghold]

Given an input of:
/data/ci/jenkins/workspace/PeterBLaboratory/Test-unittestlibobjs-10/somesubdir/somefile.txt

I have a function:


def basename(path){
def pieces

pieces = path.split("/")

context.sh 'echo first element: ' + pieces[0]
context.sh 'echo path: ' + path
context.sh 'echo parts: ' + pieces.size

def idx
idx = pieces.size - 1

return pieces[idx]
}

and I expect it to return the last element in a split array based on the
character '/'

What I'm seeing instead is:

groovy.lang.MissingPropertyException: Exception evaluating property
'size' for java.util.Arrays$ArrayList, Reason:
groovy.lang.MissingPropertyException: No such property: size for
class: java.lang.String


what the heck is going on here?

It also looks like path.split is not behaving as I'd expect and returning
an array of strings based on the delimiter. Thoughts folks?

Re: RejectedAccessException

[Peter Berghold]

OK:
After deciding to put this project aside and not look at it for a while I
came back to it and found out that I was being stupid. :-(

The constructor for the Notification class has two parameters not one and
in the heat of battle so to speak I forgot about the other one.  Once I got
that straight the job has started working again..   well... at least isn't
having that issue any more. :-)

SO apparently unclassified applies to a difference in method signatures.

RejectedAccessException

What does this mean and how do I fix it?

org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException:

somewhere in this:

} catch (Throwable e) {
currentBuild.result = "FAILURE"

notify= new Notifications(this)

notify.notifyFailed()
}
workrepo.cleanup()
throw e


seems to be the issue.

It is laid out as

}
unstable {

in a Groovy pipleline?

Define a class inside a groovy pipeline?

[Peter Berghold]

So I was playing around and tried something.   Here's a class I defined:

class MyClass implements Serializable {

  MyClass() {
  }

  def bark(){
 sh 'echo WOOF!'
 }
}

and so I instantiate it

def mc = new MyClass()

and I access my method

mc.bark()

and I get

hudson.remoting.ProxyException: groovy.lang.MissingMethodException: No
signature of method: MyClass.sh() is applicable for argument types:
(java.lang.String) values: [echo WOOF!]


So my question is: if I want to access what I perceive as normal
pipeline functions from inside a class how do I do it?  What magic foo
do I have to use?

Environmental values from a Groovy Pipeline.

[Peter Berghold]

I am most interested in using the "WORKSPACE" value in the enviromental
values. within my pipeline..  I use it as a base to create a staging
directory from so I have a value defined such as:

def outrepo="${env.WORKSPACE}/shipping-${env.BUILD_NUMBER}"

what I am getting back from that is not what I'm expecting at all.

OUTREPO: null/shipping-152


Looks like env.WORKSPACE is being resolved as a "null" instead of the
full path to the job's workspace.


Is there a different form of this I should be using?  I clearly see
WORKSPACE as being defined when within a shell I see that value
running the shell command "env."


I could hard code it I supposed, but that kind defeats the purpose a bit

Book recommendation: Mastering Jenkins

[Peter Berghold]

Hi folks,

What I'm looking for in a new book to add to my digital bookshelf is
something that will expand my knowledge (very sketchy at the moment) of
Pipelines in Jenkins.  In particular creating libraries to extend
Pipelines.

I've run into few things that I just cannot figure out by reading what's on
line for this subject.

How well does "Mastering Jenkins" by Jonathan McAllister cover those two
topics above?

try/catch in a pipeline?

[Peter Berghold]

I've noticed some "non-deterministic behavior" in my first few pipelines
and I was wondering if there i some sort of try/catch structure I could use
to catch errors.  It would sort of look like this:

try {
  sh 'some_unix_command'
} catch {
 send_mail('Step foo failed on some_unix_command')
}

Jenkins Pipelines and Puppet Code RSPEC testing

[Peter Berghold]

Hi folks,

I've been considering creating Jenkins files inside all of my Puppet
modules and converting from the way I'm dealing with our Puppet code today
to using pipelines.

A thumbnail of what I'm doing today with Jenkins is every Puppet module is
"tested" within a Jenkins job which is a mix of shell callouts and rake
callouts.   The critical steps are as follows:

bundle exec install
bundle exec rake spec_clean
bundle exec rake validate
bundle exec rake lint
bundle exec rake spec

This is all done the "Jenkins" way using the rake invocation job item with
"bundle exec" checked except for the very first step which is indeed a
shell callout

Moving to a pipeline I not only want to do the above but I'd like to
generate report especially for the rake spec step.

I get the impression that to invoke the spec steps I'd have to do so as a
"sh" step, is that true or is there some much more pipeline-ish way of
doing this?   How do I generate and publish reports from a pipeline?

Hints and nudging me in the right direction appreciated.

Weird failure in a build job (Python egg -> RPM)

[Peter Berghold]

I have a Python egg that I'm trying to repackage into an RPM for a custom
installation path. When the build is run manually it goes off without a
hitch.

When the build is run within Jenkins (which is my preferred method) the
build fails with a oddball Unicode error.

I know this is not a Python forum, but I'm in hopes someone in the Jenkins
community has seen this and has a fix for it

Re: Installing / maintaining Jenkins on a Linux host machine

[Peter Berghold]

I migrated my Jenkins installation over to Ubuntu from RHEL and haven't
looked back.  My drivers may be different than yours and my reason was I am
using Jenkins to perform CI on my Puppet environment.  Part of that is
running some tests on the Puppet code before it is deployed and this works
*much* better on Ubuntu that Red Hat which was getting rather McGiverish
given all the hacks I did to get it to work.

So I guess YMMV depending on what you are trying to accomplish.   If you
are doing this in a corporate environment make sure with the powers that be
whatever solution you pick meets with your list of acceptable solutions.

Re: SSH Slave crashing immediately after start

[Peter Berghold]

Okay I guess I'm going to have to investigate how to get the newer version
of Java on Redhat. Redhat 6 at that. Thanks for the pointers.

RHEL slave

Crafting a plugin for Jenkins

[Peter Berghold]

One of the tasks I've assigned to Jenkins is managing packages for release
to the test environment and to the production environment (two tasks?).  I
do this by creating two file trees for the packages to live in called "qa"
and "released" with their purpose being rather intuitive.   If the package
tree is being sent to the testing environment qa and released are merged
and then RSync'ed to the test environment and for production releases just
the released tree is tar-ed up and made available to operations.

I say all that to say this:  I know how to write Java code to handle file
uploads and subsequent storage in a file tree.  I've looked at a few
tutorials on writing Jenkins plugins.  What I haven't seen in my random
wanderings around is an example that would become a menu item in the left
had menu bar and manage the UI.

Is there something in github or elsewhere that I could look at that would
do something similar to what I'm after?   From a decent starting place I
can figure out the rest.

Re: Slave Jenkins on an RHEL box

[Peter Berghold]

wish that were the case.  Nope:  running the same command from the command
line yields the results I'm after.  Since the script runs as tomcat8 and
tomcat8 is trusted between the hosts I'm at a complete loss as to why this
is happening.

Slave Jenkins on an RHEL box

[Peter Berghold]

I have Jenkins running merrily on an Ubuntu box and want to set up a slave
on an RHEL box.

Created a script on the RHEL box that essentially launches a script that in
turn launches the slave.jar.  Trying to invoke it over SSH and there's
where things take a turn for the worse.

I'm getting this:

[11/14/16 16:22:37] Launching agent
$ /usr/share/tomcat8/startSlave0
Host key verification failed.
ERROR: Unable to launch the agent for java.io.EOFException

That first line is a script on the master that does the SSH.What
I'm not sure about is exactly what is complaining about Host key
verification.  Given I can run that script by hand and it starts the
jar file I'm a bit confused about what's going on here.

Building RPMS from Jenkins job

[Peter Berghold]

I wonder if anybody else has had the experience that I've had.  I have
several jobs running in Jenkins right now that create an RPM file and
deliver it to a repository. What I've observed is the rpmbuild command can
error out and the build still get marked successful.

Anybody else running into this?  Any thoughts?

Rake invocation broke -- fixed it already

[Peter Berghold]

Using the Rake plugin with Jenkins got me into a bit of trouble this
morning.  Seems it got broken somewhere along the way issuing the following
error:

/usr/lib/ruby/site_ruby/1.8/rubygems/dependency.rb:319:in `to_specs':
Could not find 'rake' (>= 0) among 11 total gem(s) (Gem::LoadError)
Checked in 
'GEM_PATH=file:/usr/share/tomcat6/webapps/jenkins/plugins/ruby-runtime/WEB-INF/lib/stapler-jruby-1.209.jar!/gem:/usr/lib64/ruby/gems/1.8',
execute `gem env` for more information
from /usr/lib/ruby/site_ruby/1.8/rubygems/dependency.rb:328:in `to_spec'
from /usr/lib/ruby/site_ruby/1.8/rubygems/core_ext/kernel_gem.rb:65:in 
`gem'


After running the rake invocation from the command line I deduced that
the issue was all about the GEM_PATH variable which I then set
globally in the Jenkins settings.


Not complaining, just posting this so I might be able to save others
some time troubleshooting.

cpan2rpm as part of a Jenkins job

[Peter Berghold]

Hi there,

I'm trying to run the CPAN application cpan2rpm to run as part of a Jenkins
job.  It isn't working and causes failed builds.

When I log in as the Jenkins user (tomcat in this case) and manually run
the cpan2rpm command from the command line exactly as it looks in the job
it runs fine.

Run as a job it exits without any sort of error which of course makes it
difficult to figure out why it is failing.

I've also asked about this over on PerlMonks and so far no insight.
Anybody out there creating RPMs for Perl modules with Jenkins?

Publishing to MediaWiki

[Peter Berghold]

Nope.  There's a single war file in /var/lib/tomcat6/webapps named

war file into.

Dead Parrots (threads)

[Peter Berghold]

I have a rather busy build flow that invokes other builds sometimes in
parallel and other things serially.  What I've been observing is thread on
the subordinate jobs dying with an error saying "Build XXX already exists"
and interestingly enough those build numbers don't show up in the build
history.

I'm running version 1.633 which I just upgraded to two weeks ago. That, by
the way, was a flaming disaster causing me to lose all my old job
definitions, but that's another story.

SO:  what is causing the threads to die and what do I do about it?   It's
becoming ridiculous...

Global environmental variables

[Peter Berghold]

Riddle me this Batman.

Is there a way in Jenkins to set a global value that build jobs can access
in a shell?

Reason I ask is I'm about to create a build job that sets up files for
release by gathering a host of modules, staging them and then creating not
one but two tarballs for distribution.   I need to designate what the build
tag is to help name the tarballs.

modules-{TAG}-{SEMANTIC VERSION}-release.tar.gz

I'd like the to set the TAG and SEMANTIC VERSION in one place and have it
carry everywhere

anonymous user?

[Peter Berghold]

I really don't want an anonymous user, but none-the-less it's there.  I'm
in the process of re-installing Jenkins in my own personal environment and
when I enable security and save my changes Jenkins abends and complains
that

anonymous is missing the Overall/Administer permission

Correct me if I'm wrong here, but isn't that a huge security hole?

Re: Automated deployment process through Jenkins

Not much to go on htere, but my builds I've implemented in Jenkins look a
lot like shell scripts using the same techniques I'd use manually.

For instance I'll build a .war file for a web application and then just
send it to the appropriate directory on the target server using scp.  Make
sure you have SSL certs in place making Jenkins trusted in the landing zone.

Introduction

[Peter Berghold]

Hi folks, 

Thought I'd drop a line introducing myself.  I'm the sole developer for the 
group I work for that is doing a Puppet infrastructure deployment.  As part 
of that project I'm writing Puppet modules and plan to use Jenkins to 
automate testing of the modules (syntax, code coverage, etc) as well as 
promoting modules to the test environment and later bundling up tarfiles to 
release to production.

A bit overwhelmed right now trying to sort out just where to start and it 
looks like Jenkins is going to exceed my requirements. 

Will mostly be lurking for the time being but hope to be able to contribute 
once I've some experience with this tool.

Re: How can i install jenkins server on rhel 7 machine ? Have anyone done it earlier ?

[Peter Berghold]

My favorite way is to use the WAR file and stick it into 
${CATALINA_HOME}/webapps and let tomcat do the rest.
