I am working on micro-service base Jenkins pipeline. There is similar code pattern / structure in Bitbucket repository for Java and angular based code. Can I manage multiple repositories with single pipeline with dynamic approach which can provide filter option (like AJAX in java) in drop down like I can get more than one repositories in drop down option and I can select any repository, based on this repository, I can get branches from this repository in next drop down and I can execute Jenkins pipeline.
Do we have any Jenkins plugin which can provides filter option for Bitbucket repositories in Jenkins.
Presently I am using Git parameter option in Jenkins pipeline (Build with parameter) and then created several pipelines.
Are you saying that you want a job in which you can select a repository and then select a branch from that repository and hit GO and build that branch of that repo? If this is the case then the answer is no.
You would have one Job per repository, and if that job is a multibranch pipeline then you would be able to select the branch to build from there.
You can enable all the repos and branches to use the "same" pipeline that you then submit parameters to using a Shared Library

I'm currently trying to set up a build job connected to multiple (3) svn repositories with single pipeline, with Poll SCM scheme. All the contents from the repositories build into a single artifact. Repositories are, e.g., say:
https://myrepo.com/mainSrc/main
https://myrepo.com/libs/library1
https://myrepo.com/libs/library2
When I set all this repos inside Pipeline configuration, the build job successfully checkouts all the paths to the workspace.
However, the point is, I need to track which repository started the build job, to write some conditional steps. Is there a solution for this? I googled for it, there are some ways to obtain svn revision for a path, however it's not what I'm looking for.
I have multiple repositories which require a cd pipeline and all the repositories have their own jenkinsfile with same name. I have configured one jenkins pipeline for all the repositories by adding multiple repositories in "pipeline script from SCM" section.
When any of the repository is updated the pipeline triggers but it uses jenkinsfile of the first repository mentioned in the list of repos.
Is their anyway we can change this behaviour and make the Jenkins job run Jenkinsfile from a repository which triggered the build.
This can be done by shared library https://www.jenkins.io/doc/book/pipeline/shared-libraries/
https://www.tutorialworks.com/jenkins-shared-library/
You can define various logic and functions to manage multiple repositories and their variables.
Also, try to make generic script which can behave based on the supplied parameters.
I have 2 separate projects in AzDo, project-1 contains repo to build docker image and tag it accordingly like 1.0.0 , 1.0.1 etc. and in another projects-2 there are 2 separate repos which uses these tags. currently this is manual in repos#project-2.
My question is how can I automate the process in AzDo, that means if there is a new tag for docker in repo#project1 then it will automatically build the repos in project-2 with this new docker tag.
e.g. currently project-1 has image:1.0.0 and this is used in 2 repos in project-2 manually referring to 1.0.0.
Now I build a fresh tag in project-1 with tag 2.0.0, so how can I automatically build 2 repos#project-2 with this new 2.0.0 . Is there any link/signal from one build/release pipeline to another pipeline/project?
Any advice is greatly appreciated.
The easiest way it will be to use pipeline triggers which allow you to trigger one pipeline after another. You may have an issue fetching docket image tag but simply you may resolve this by hitting your container registry.
Please check out also stages filter, maybe they will provide a value for your case.
In this sprint, we added support for 'stages' as a filter for pipeline resources in YAML. With this filter, you don't need to wait for the entire CI pipeline to be completed to trigger your CD pipeline. You can now choose to trigger your CD pipeline upon completion of a specific stage in your CI pipeline.
Another option will be to use webhook when your image is pushed to container registry and trigger another pipeline over REST API.
According to your description, seems you are talking about two different team project.
Is there any link/signal from one build/release pipeline to another pipeline/project?
You want to trigger a pipeline in another team project.
In the classic editor, pipeline triggers are called build completion triggers. You can select any other build in the same project to be the triggering pipeline.
Thus you have to specify pipeline triggers directly within the YAML file instead of configuring build completion triggers in the UI.
# this is being defined in app-ci pipeline
resources:
pipelines:
- pipeline: securitylib # Name of the pipeline resource
source: security-lib-ci # Name of the pipeline referenced by the pipeline resource
trigger:
branches:
- releases/*
- master
To trigger a pipeline upon the completion of another, specify the triggering pipeline as a pipeline resource.
Note: If the triggering pipeline is in another Azure DevOps project, you must specify the project name using project: OtherProjectName.
More detail sample and limitation refer: https://stackoverflow.com/a/61398607/5391065
For Classic editor, you need to use some 3rd-paty extension such as this one--Trigger Azure DevOps Pipeline, it's able to select other project where the pipeline resides.
We are currently using Windows \ Jenkins 2.107.1 (no pipeline), and I am researching going to pipeline. We have a nightly build job, that fetches from repositories, and submits and waits on other jobs. I see 9 jobs running on the same Master node (we only have a master), at the same time. I am not clear on if we should have one Jenkinsfile or multiple Jenkinsfiles. It will not be a multibranch pipeline, as we do not create test branches and then merge back to a master. In the repository we have product1.0 branch, product2.0 branch etc, and build only one branch (the latest one). While I do like the Blue Ocean editor, it is only for MultiBranch pipelines.
Do I combine all the jobs into one Jenkinsfile, or create multiple jenkins files for each of the existing jobs (Jenkinsfilestart, JenkinsfileFetchCVs, JenkinsFileFetchGit, Jenkinsfilenextjob,etc., and have one call the other)?. Do I create all the old jobs as Jenkinsfiles, or scripts executed by the one master Jenkinsfile? Do I do this in Declarative or script ?
Have set up Jenkins pipeline on test VM, but not clear on which way to go yet.
Looking for directions and\or examples. Is there documentation on how to convert existing Jenkins non-pipeline systems?
I found this after doing the initial post...https://wiki.jenkins.io/display/JENKINS/Convert+To+Pipeline+Plugin.
It does help a little in that it gives you some converted steps, but cannot convert all the steps, and will give comments in the pipeline script "//Unable to convert a build step referring to...please verify and convert manually if required." There is an option "Recursively convert downstream jobs if any" and if you select that, it appears to add all the downstream jobs to the same pipeline script, and really confuses the job parameters. There is also an option to "Commit JenkinsFile". I will play with this some more, but it is not the be all and end all of converting to pipeline, and I still am not sure of whether I should be have one or more scripts.

Let’s see if I have my research to date correct…
A Declarative pipeline (Pipeline Script from SCM), is stored in a Jenkinsfile in the repository. Every time that this Jenkins job is executed, a fetch from the repository is done (to get the latest version of the Jenkinsfile).
A Pipeline script is stored as part of the config.xml file in the Jenkins\Jobs folder (it is not stored in the repository, or in a separate Jenkinsfile in the jobs folder). There is a fetch from the repository only if the job requires it (you do not need to do a repository fetch to get the Pipeline script).
Besides our nightly product build, we also have other jobs. I could create a separate Declarative Jenkinsfile for each of them (JenkinsfileA, JenkinsfileB, etc.) for each of the other jobs and store then in the repository also (in the same branch as the main Jenkinsfile), but that would mean that every one of those additional jobs, to get the particular Jenkinsfile for that job, would also need to do a repository fetch (basically fetching\cloning the repository branch for each job, and have multiple versions of the repository branch unnecessarily downloaded to the workspace of each job).
That does not make sense to me (unless my understanding of things to date is incorrect). Because the main product build does require a fetch every time it is run (to get any possible developer check-ins), I do not see a problem doing Declarative Jenkinsfile for that job. For the other jobs (if we do not leave then for the time being in the classic (non-pipeline) format)), they will be Pipeline scripts.
Is there any way of (or plans for), being able to do Declarative pipeline without having to store in the repository and doing a fetch every time (lessening the need to become a Groovy developer)? The Blue Ocean script editor appears to be an easier tool to use to create pipeline scripts, but it is only for MultiBranch pipelines (which we don’t do).
Serialization (restarting a job), is that only for when a node goes down, or can you restart a pipeline job (Declarative or Scripted), from any point if it fails?
I see that there are places to look to see what Jenkins plugin’s have been ported to pipeline, but is there anything that can be run to take a look at the classic jobs that you have, to determine up front which jobs are going to have problems being converted to pipeline?

Studying and playing with pipelines. I see that you can use Declarative in the Pipeline Scrip window, but it still stores it in the config.xml file. And I have played with the combination of both Declarative and non Declarative in the same script.
I am trying to understand the Blue Ocean interface, the word "MultiBranch" is throwing me a little. We do not create test branches, and them merge them back into the master. In the repository, we have branches for each release of the product, and we rarely go back to previous branches\versions. So, if I am working on branchV9 right now, do I also need a Jenkinsfile in the Master branch, or any other of the previous version branches?
I have been playing with Blue Ocean (which only does MultiBranch pipelines). I am on a Windows system, Jenkins 2.176.2, and have all the latest Blue Ocean plugins as of today (1.18.0). I am accessing a local Git repository (not GitHub), and am running into the following...
If I try to use use “c:\GitRepos\Pipelines1.git”, i get "not a valid name"...
Why does it do this?
If you have a single job that you would be executed on multiple branches (with possibly optional stages, depending on the branch name or tag or other) then you still could utilize multi branch pipeline.
In general I would say that paradigm shift focuses mainly on converting the old jobs to stages in order to automate your build process. If you would have semi/fully automated CI/CD flow this could look like
Multibranch pipeline project (all branches) with the following stages (1st jenkinsfile)
build (all branches)
unit tests (all branches) publish report
publish artifacts (master and release branches)
build and publish docker (master and release branches)
deploy to test (master and release branches)
run integration tests (master and release branches)
deploy to staging (master and release branches) possibly ending with manual step if result of deployment was as expected
deploy to production (release branches)
Pipeline job for nightly tests (other jenkinsfile), what's the result here? Would it break CI/CD flow?
I am currently using Cloudbees Jenkins Coreas my Jenkins solution.
I am using Jenkins Pipelines to write our Jenkins job configuration. These pipelines are stored in GitHub repositories. Each Jenkins job when created is connected to a GitHub Repository where the source code is pulled from, and that's where the Jenkinsfile is stored and Jenkins reads from.
Below are some high-level photos for how our Jenkins jobs are configured.
The advantage of the way these jobs are configured is the Jenkinsfile is always read from the master branch. Meaning if a rouge developer tries to remove stages from the Jenkinsfile from within there own branch, it doesn't matter because the Jenkinsfile is always read from the master branch (which is always protected).
However, the one massive drawback to this - is how do teams and developers who are devops engineerings make changes to the Jenkinsfile? For example, let's say a developer creates a branch called feature-jenkins-search and they edit the Jenkinsfile adding a new stage in the pipeline. Whenever they push these changes to GitHub to test - they can't test as it's always read from the master branch? Meaning devops engineerings have to work directly on the master branch? Surely this is not the best way to go and there is a better configuration to set?
We do want to still provide the security that if a developer is rougue and
You should really look into the Jenkins multi-branch pipeline feature. The Jenkins multi-branch pipeline allows to create a single configuration item in Jenkins (a bit like a folder) that can detect all the branches and pull requests in a GitHub repository with a Jenkinsfile and build them using automatically created jobs. Inside this multi-branch pipeline object when it is configured in Jenkins, you will find a number of jobs to build the various branches and pull-requests in the GitHub repository.
So your developers should maintain a Jenkinsfile in every branch they work on in GitHub to build that branch in your Jenkins server.
It is possible to make the Jenkinsfile do branch specific handling if required with conditional stages / when conditions in the Jenkinsfile pipelines in each branch.
You can lock down the master branch so that code and Jenkinsfile changes from other branches can only be merged with an approved PR (pull request). There is good integration between Jenkins and GitHub such that you can configure the master branch to only allow a PR to be merged if the PR is buildable in Jenkins. So if developers add new stages / processing to a Jenkinsfile on a branch being merged to master, it should be validated so that builds of your master branch are not broken.
There is a lot of configurability in the Jenkins multi-branch pipeline object for detection and handling of branches and it may be necessary to experiment to get it right for what you need with your team. If you cannot find this feature in Jenkins, it is probably because the correct Jenkins pipeline and GitHub related plugins are not installed.
You could also have a look at a similar Jenkins feature called the Jenkins GitHub Organization Folder which allows to detect and build all repos and branches at a GitHub Organization level. But when starting out, I would suggest to look into the multi-branch pipeline at the single repo level first.
These features are discussed in the Jenkins pipeline documentation. We use these features with our internal GitHub and Jenkins server and it works very well.
I think you will find the idea of using a single Jenkinsfile in the master branch to be used for building all branches is unworkable, as you have seen!
