QUESTION
Today during a code review of my CI/CD scripts, I came up agst. the following issues with my peer.
- Was using a docker file which I then installed sdkman and then used sdkman to get the correct version of java and maven for my legacy project. I then used the docker-dind service to build my image using a gitlab runner. It is an oft used pattern documented within Gitlab as best practice. I was using an official image and amending it so that maven could run and build my WAR file. It has all worked fine. I also installed sdkman - so I can use this image for other flavours of maven+legacy-jdk7.
None of this was original stuff but adapted from a blog by Szymon Stepniak [https://e.printstacktrace.blog/using-sdkman-as-a-docker-image-for-jenkins-pipeline-a-step-by-step-guide/]
Essentially I had an image with Maven 3.5.4 & Java 7.x.x-zulu, instead. I also set it up with a non-root user. With an .m2 folder + settings.xml which is needed for Maven. It does my building of this legacy WAR file.
But, I was told to drop the idea of creating my slightly amended docker image and to use one that is already made up namely maven:3.2.5-jdk-7u65
Ques 1. I was using an offical image namely debian:stretch-slim and amending it slightly. Atleast, my Dockerfile will say what is happening to my image. So, all of it's provenance is all well known. So, why is that practice being frowned upon ?
Ques 2. I cannot find this image maven:3.2.5-jdk-7u65 on docker hub as a SAFE & OFFICIAL image to use ?
Ques 3. When I use the maven:3.2.5-jdk-7u65 , it complains that this image is deprecated, but continues, it also complains about some public gpg keys being out of use, but continues, and the Maven build fails. The POM directives I am using basically are not covered by maven:3.2.5
What should I do and how should I approach this task ? What is best practice ? Why can't I find many official legacy maven + legacy jdk6,7 images ?
...ANSWER
Answered 2022-Apr-08 at 00:58There's a lot of "it depends", and one of the things it may depend on is your local legal compliance requirements. I would suggest either:
- Use a current version of a Docker Hub image, if it's allowed; or else
- Build an image based on a known and allowed distribution base image
One thing to be conscious of with the Docker Hub images is that there's a specific set of versions they support, and versions other than this aren't rebuilt at all. Consider the maven
image: there are various variations on maven:3.8.5
out there. If you build your image FROM maven:3
and you docker build --pull
then you will get updates on this, both in Maven and the underlying Linux distribution image. If you name a super-specific FROM maven:3.8.3
then it will never be rebuilt, even if the underlying Linux distribution or JVM has a critical security update.
You're probably seeing some of this with the maven:3.2.5-jdk-7u65
image you've found. The image exists on Docker Hub but it hasn't been rebuilt in a long time. (For that matter, even the oldest openjdk
image is based on Java 8.) So you probably could use it, if you really wanted to, but I wouldn't treat it as reliable or maintained.
So if you really need a very very old version of Java (which will be end-of-lifed in just a couple of months) I'd suggest the approach you have now is the best one: start FROM
a reasonably current Linux distribution that gets security updates, download the newest version you can (it looks like Java 7u80 is publicly available and 7u331 with a paid subscription) and rebuild it occasionally. It will be on you to take updates as they're released and as the base Linux image gets updates, but this will be more updates than the unmaintained image you found gets.
QUESTION
I have a Jenkins pipeline that I'd like to run on either a params-specified agent or master
. The pipeline code that implements this is:
ANSWER
Answered 2022-Mar-30 at 01:47h pipeline/job has a trusted agent list, more job succeed on the agent, the agent sit in the top on the list, pipeline/agent will pick top agent from list.
If your pipeline already run on master for several times and all succeed, even you give another agent to choose, pipeline always pick the most trusted agent firstly

I'm setting up a jenkins job which will be triggered whenever a artifact is deployed in jfrog. I have followed the steps present in the below documentation and i was able to trigger the job.But unfortunately, i'm not able to get the variables values.I'm not sure how to see the payload which we are receiving on the jenkins side to pull the required variables.Guide me

QUESTION
So I have a groovy script called "deployer.groovy" that is in a git repository called "jenkins-pipeline-library". (https://github.com/xyzDev/jenkins-pipeline-library) there is nothing else in this repository just this groovy file in the main branch.
Also, I have a Jenkinsfile that is in a different git repository. I cannot put both of these file in a same Git repository.
(because im not allowed to, the idea is to be able to run this deployer.groovy by using Jenkinsfile so that people dont see the content of the deployer.groovy but be able to use it)
I am trying to load this deployer.groovy in my Jenkinsfile and then run it.
Is there any way to do this? Please any suggestions would be highly appreciated.
...ANSWER
Answered 2022-Feb-02 at 18:56There are several ways to achive this.
Git SubmoduleYour jenkins-pipeline-library
could be git-submodule in other repositories.
QUESTION
It seems like it's really difficult to be able to store a bunch of variables for use in shared code in Jenkins/Groovy scripted pipelines. I've tried a bunch of methods and none of them seem to give the desired result.
This method looked the most promising, but the values all came back as null in the calling pipeline. Get Global Variables in jenkins pipeline.
My codes is something lie
...ANSWER
Answered 2022-Jan-21 at 17:37In general, env
is only available once the pipeline has started, but groovy scripts are resolved much earlier.
I'm using static class members as global variables. Applied to your code sample, it would look like this:
JobHelper.groovy
QUESTION
I opened an old ticket without answers : How to send attachments through jenkins pipeline using mail
Do you know if it's possible to send an email attachment with mail
. I know that it's possible to send it with emailext
but it's not installed on our Jenkins and the team doesn't want to install it.
Please let me know if it's atleast possible because if it's not, it's a good reason to pressure the IT team in charge of the Jenkins :)
Thanks in advance
...ANSWER
Answered 2022-Jan-07 at 14:44No you cannot send attachments with the built-in mail
steps.
Its parameters are quite limited https://www.jenkins.io/doc/pipeline/steps/workflow-basic-steps/#mail-mail
You would need email-ext
for this.
e.g. How to send email with attachment in jenkinsfile (Groovy Script)?

Answered 2021-Dec-29 at 15:40First, I would highly recommend you to upgrade to the latest version is your current version is "rather old". Version 6.0 was just released few days ago. I don't any open bug related to that, except this bug that been solved many releases ago. You can try importing using a zip file, in a single request (which is more efficient btw). Maybe this approach implicitly addresses your problem, in the version in that you have.
Example:
QUESTION
For my ETL scripts I am using a continuous development infrastructure: if the test workflow is successful, it means that it can be pushed into production and then be run during the night, if the test is not successful then the changes are not pushed but the production scripts still run.
So far I am manually rebasing my test branch to my master branch every time I make a successful change. I would like to automate this so that, once the test pipeline job is complete and successful, Jenkins automatically rebase the master branch on the test branch and push it on the remote repository.
Here's my current jenkins pipeline code mock-up (Jenkinsfile_test):

With Jenkins Declarative Pipelines you can loop over a map to run stages for each element:

Install jenkins-pipeline
You can use jenkins-pipeline like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the jenkins-pipeline component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
