Re: Pipeline DSL, IntelliJ, and maven

[Indra Gunawan (ingunawa)]

Somehow is there other IDE that can be supported.  Can Jenkinsfile syntax 
hightlighting be supported in SublimeText and recently Visual Studio Code.

Thank you

It works for me with IntelliJ 2016.3.4.

Steps:

1. Create a new Java project with Groovy dependency.
2. Right-click 'src', New, Groovy Script, call it 'dsl' and select kind 
'GroovyDSL script'.
3. Paste in the output from Jenkins and save.
4. 'Activate back'
5. Right-click 'src', New, Groovy Script, call it 'Jenkinsfile' and select 
kind 'Groovy script'.
6. Paste in your Jenkinsfile
7. Enjoy autocompletion etc.

Re: shell execution produces "couldn't flush stdout" error

[jjackson]

I'm seeing something similar whenever I try to use pipes in a jenkins 
pipeline sh .  I've asked a similar question on SO 
http://stackoverflow.com/questions/42568201/jenkins-pipeline-sh-does-not-seem-to-respect-pipe-in-shell-command.
 
 I can't seem to get piped shell commands to work, which seriously limits 
the power of what you can do.

Re: Pipeline DSL, IntelliJ, and maven

[Justin Knowles]

Not trying to be obtuse, but are there even install instructions on that
page or directions for how to get IntelliJ to understand
GroovyDSL/Jenkinsfile? I see the "Describing GroovyDSL internal language in
its own terms" section mentioning IDEA PSI but I have no idea where it is
or how to set it up? Am I looking at the right section? This is for an
existing project, FWIW.

The instructions on

Re: Pipeline DSL, IntelliJ, and maven

[Justin Knowles]

Is there a guide on what I do with that GDSL? If I'm understanding
correctly the instructions here (
https://st-g.de/2016/08/jenkins-pipeline-autocompletion-in-intellij) say:
1. take the raw GDSL from /pipeline-syntax
2. drop it into a file called pipeline.gdsl
3. put it somehwere on the classpath

I've done that but I'm not seeing any syntax highlighting or autocompletion
in my Jenkinsfile. I'm not developing a plugin for Jenkins or anything, I
just want IntelliJ to recognize the Jenkinsfile and provide highlighting,
style fixes, etc.

There's a GDSL you can download from /pipeline-syntax that provides Pipeline 
syntax, would that work? If not, could you explain what you're asking for?

Pipeline DSL, IntelliJ, and maven

[Justin Knowles]

Has anyone integrated a plugin with IntelliJ for editing a Jenkinsfile when 
writing Jenkins pipelines? Where can I find how to do this? I'm not seeing 
any plugins in the plugin repositories or on google, and the closest thing 
I've found to a howto was using Gradle and not maven, so I'm unsure of how 
to take those instructions and apply them to my setup.

Locking from shell

[Artur Szostak]

Hello,

Does anyone know if the Lockable Resources plugin exposes a REST API or any 
other mechanism to be able to grab a lock from within a shell build step?
Is there any other locking plugin that can support this?
I need this to support dynamic resource locking. Specifically, I only know what 
subsequent resources need to be locked after the first few stages of my build 
process from the command line tools.

Alternatively, is it possible with the pipeline plugin to read in output from a 
build step on a slave and use that within the lock statement of a pipeline 
definition?

Kind regards.

Artur

Re: Problem with runnig Jenkins Slave using ssh key

['Björn Pedersen' via Jenkins Users]

Probably you need to generate new ssh keys:

[Declarative pipeline] Using Docker environment variables

[Peter Marcoen]

In my Dockerfile I install Ant and declare environment variables pointing 
to this Ant installation:

FROM openjdk:7# Install wgetRUN  apt-get update \  && apt-get install -y wget \ 
 && rm -rf /var/lib/apt/lists/*# Install antENV ANT_VERSION 1.9.6RUN cd && \
wget -q 
http://archive.apache.org/dist/ant/binaries/apache-ant-${ANT_VERSION}-bin.tar.gz
 && \tar -xzf apache-ant-${ANT_VERSION}-bin.tar.gz && \mv 
apache-ant-${ANT_VERSION} /opt/ant && \rm 
apache-ant-${ANT_VERSION}-bin.tar.gzENV ANT_HOME /opt/antENV PATH 
${PATH}:/opt/ant/bin# Create user jenkinsRUN groupadd -g 999 dockerRUN useradd 
jenkins -u 999 -g 999 --shell /bin/bash --create-homeRUN echo 'export 
ANT_HOME=/opt/ant'  >> /home/jenkins/.bashrcRUN echo 'export 
PATH=$PATH:/opt/ant/bin' >> /home/jenkins/.bashrcUSER jenkins


As you can see I do 2 things: I use the docker ENV statement which should 
set the environment variables, then additionally I add export statements to 
the jenkins' user bashrc.
However, inside my Jenkins pipeline these environment variables don't 
appear to be set, no matter what I do. 
When I echo my path I see the following:

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/opt/jenkins/bin:/usr/lib/oracle/12.1/client64/bin:/usr/lib/oracle/12.1/client64/lib


When I echo my .bashrc there are indeed the following lines:


export ANT_HOME=/opt/ant
export PATH=$PATH:/opt/ant/bin


So why is my path set incorrectly?

I suspect the reason is that Jenkins overwrites the path when running docker, 
and I can kinda see this in the console output of Jenkins:


docker run -t -d -u 999:999 -w /opt/jenkins/workspace/testws -v 
/opt/jenkins/workspace/testws :/opt/jenkins/workspace/testws :rw -v 
/opt/jenkins/workspace/testws @tmp:/opt/jenkins/workspace/testws@tmp:rw -e 
 -e  -e  -e  -e  -e  -e 
 -e  -e  -e  -e  -e  -e 
 -e  -e  -e  -e  -e  -e 
 -e  -e  -e  -e  -e  
--entrypoint cat 4b4e7722d454ad10aec20f95d2bb1c1ce527c880


And if I look in the documentation it even says how to set environment 
variables: 
https://github.com/jenkinsci/pipeline-model-definition-plugin/wiki/Environment-variables

But this doesn't make sense to me. Isn't the whole point of using Docker that 
your environment will consistently be the same? So why would I want to use 
environment settings or tools from jenkins if I'm using docker? Then the 
environment is also not defined in a file anymore.


Is there any way around this? Or am I looking at it all wrong?


This is the Jenkinsfile that I use:


pipeline {agent {dockerfile {
label "docker"}}stages {
stage("build") {steps {
sh 'echo $PATH'sh 'cat ~/.bashrc'   
 }}}}

Re: Security question

[Mark Waite]

Jenkins executes processes on agents.  Since you're allowing a process to
compile code and execute tests on an agent, you're accepting that the agent
is at risk from that compilation and execution.

One of the way to reduce that risk is to never execute build jobs on the
master agent.  That also help scalability, since the master agent generally
has plenty of work to do being the master of all the other agents.

Another way to reduce that risk is to create and destroy an agent for each
build process.  Then the damage which the build and test process can do is
limited to the agent running the build.  There are plugins which will
create and destroy virtual machines from Jenkins.  There are plugins which
will create and destroy Docker instances from Jenkins.

Security question

[andrew . lucas]

 

Hi,

We have a Jenkins installation running under windows, pulling from SVN, 
that is building some VS2010/VS2015 projects.

Those projects are using google test for automated testing.

How does one prevent those google test projects from accessing the build 
server from outside of the build workspace?

That seems to be a big security hole. You seem to be able to impact the 
whole build server from a google test project.

Google test is not something that is installed. They are just libraries 
included with the project.

Am I missing a security setting in Jenkins somewhere? How do I resolve this?

Thanks

SCM initiated builds with scripted/imperative pipeline

[Gardell, Steven]

I am trying to get parallel builds to run as described in several different 
places including:

https://www.cloudbees.com/blog/parallelism-and-distributed-builds-jenkins
https://jenkins.io/blog/2016/10/16/stage-lock-milestone/

What I find is that this mechanism (basically "lock(...) { milestone() { 
do-build }}") works at the scripting level when I invoke the build manually but 
not for SCM (in my case Perforce) initiated builds. This is true with both 'SCM 
polling' and 'Perforce triggered' builds. It seems that this SCM initiation 
simply doesn't run if the job is currently running. This same build is being 
triggered by SCM polling when it is not currently running, so I am by that 
minor challenge.

Any suggestions?

Re: Is there any way for a jenkins project to use the Gitlab plugin but only be built periodically and not when a change is pushed?

[suresh kumar]

Could you share the full config of Job and Check the Gitlab hooks.

Re: User input in declarative pipeline

[Bill Dennis]

I've seen it used in a 'when' condition - in this example online: 
https://github.com/sta-szek/pojo-tester/blob/master/Jenkinsfile

Here is an extract from that:

when {
expression {
boolean publish = false
if (env.DEPLOYPAGES == "true") {
return true
}
try {
timeout(time: 1, unit: 'MINUTES') {
input 'Deploy pages?'
publish = true
}
} catch (final ignore) {
publish = false
}
return publish
}
}


But is doesn't seem to usable as a 'first class' step in a steps section 
without dropping into script.

Bill
