I currently have a project set up in Bamboo that has various tasks attached to it ranging from: source code checkouts, scripts and commands.
I would like to transition over to Jenkins and perform the same action and found that Pipelines may be what I am looking for.
Can anyone provide me with a basic understanding of how I can create a Pipeline or freestyle job in Jenkins with sequential tasks that are executed as part of a build? A project in Bamboo has a plan with various tasks and I would like to replicate the same thing in Jenkins.
Here is an example of what my Bamboo tasks look like:
Thanks

I am trying to understand how to best deploy an instance of Jenkins, complete with plugins, users and jobs using Chef. I am currently using the Chef Jenkins Supermarket cookbook.
I am attempting to achieve automated deployment of our Pipelines as part of the project. From what I have gathered, the best way to go about this is to have Chef configure a seed job in Jenkins initial setup and configuration.
The seed job should specify, among other things, the git repository from which to find and use a Jenkinsfile for a given job. I've found this resource by Daniel Spilker to be helpful in explaining seed jobs.
So the seed Jenkins job would be run, which would then generate the Jenkins job we have just scripted with it (in this case the seed job would be to pull the Jenkinsfile from source control and configure a new Jenkins job (our pipeline), with the details of the Jenkinsfile).
Am I understanding this correctly as the proper way to not only automate Jenkins job configuration, but also as the proper way to always have an up to date job configuration for any given job in the event the job configuration were to change?
If we used a seed job to setup our pipeline, what are some possible solutions to having the initial seed job run automatically once Jenkins is fully configured by Chef?
As for job configuration changes that may occur over time, would we need to setup the seed job to poll source control for any changes in the Jenkinsfile periodically in the event the Jenkinsfile has been modified? (It may be helpful to note that we are currently using BitBucket for source control).
Just getting started with pipeline as code. Thanks to everybody in advance for their patience and guidance.
I've mentioned this a bit in your other questions, but the least painful approach is to treat Jenkins as a database, not a web service. Have Chef do the basic install, but then configure the initial bits by hand. For DR, rely on your backups rather than Chef.
I am working with Jenkins, and we have quite a few projects that all use the same tasks, i.e. we set a few variables, change the version, restore packages, start sonarqube, build the solution, run unit/integration tests, stop sonarqube etc. The only difference would be like {Solution_Name}, everything else is exactly the same.
What my question is, is there a way to create 1 'Shared' job, that does all that work, while the job for building the project passes the variables down to that shared worker job. What i'm looking for is the ability to not have to create all the tasks for all of our services/components. It be really nice if each of our services/components could have only 2 tasks, one to set the variables, another to run the shared job.
Is this possible?
Thanks in advance.
You could potentially benefit from looking into the new pipelines as code feature.
https://jenkins.io/doc/book/pipeline/
Using this pattern, you define your build pipeline in a groovy script rather than the jenkins' UI. This script is then kept in the codebase of the project it builds in a file called Jenkinsfile.
By checking this pipeline into a git repository, you can create a minimal configuration on the jenkins' side and simply tell it to look towards a specific repo and do the things that pipeline says to do.
There's a few benefits to this approach if it works for your setup. The big one being that your build pipeline will be fully versioned just like the project it builds. And the repository becomes portable, easily able to be built on any jenkins' installation across as many jobs as long as the pipeline plugins are installed.
I am actually implementing the continuous integration pipeline of the company I am working for with the help of Jenkins.
What I have done so far is a bit basic:
Create as many jobs as stages in my pipelines and then Build a pipeline view with the jobs I created before. So far so good but just for the test pipeline I have created.
I mean, this pipeline runs over a project. If I want to apply the same 'pipeline actions' against other project, I have to create again all jobs that are within the pipeline > create the Build a pipeline view and I will have another pipeline.
I am trying to extrapolate this into the Jenkins a code concept so that my pipeline will be formed by groovy code and the only thing left to do would be change the name of the project.
What do you guys think about my approach on building Jenkins pipelines?
Cheers,

I had some jenkins standalone jobs to build, package and deploy. Now I am connecting them and making 'build' job trigger 'package' job , and 'package' job to trigger 'deploy' job and am passing the required parameters between them.I can also see them neatly in pipeline view.
My question is, can this technically be called a pipeline? Or can I call it a pipeline only if I use pipeline plugin and write groovy script?
Thanks
p.s: Please do not devote this question. It is a sincere question for which I am not able to find the right answer. I want to be technically correct.
In Jenkins context, a pipeline is a job that defines a workflow using pipeline DSL (here, based on Groovy). A pipeline aims to define a bunch of steps (e.g. build + package + deploy in your case) in a single place, allows to define a complex workflow (e.g. parallel steps, input step, try/catch instructions) that can be both replayed and versionned (because it can be saved to git). For more information you should read Jenkins official pipeline documentation that explains in details what a pipeline is.
The kind of jobs you are currently using are called freestyle jobs, and even if they do define a "flow" (by chaining jobs together), they cannot be called pipelines jobs.
In short, pipelines are jobs that use pipeline plugin and groovy script syntax to define the whole application lifecycle, and standard Jenkins 1.x jobs are called freestyle jobs.
I've just started working with the Workflow plugin.
The set-up I have currently consists of a Workflow script that uses the build step to basically define a pipeline made up of multiple downstream jobs.
This is working well but their there isn't really any link between the output of Workflow build and the output from all the downstream builds, is their a way to either,
Link from the Workflow project build output to all the corresponding downstream builds.
Capture the console output of the downstream jobs and include it in the output of the Workflow job.
I'm hoping with either of these options it will be possible to see the output from the whole pipeline via the Workflow job output.
IMO, the intention of Workflow is to replace pipelines of various Jenkins jobs with just a single job. This may be why Workflow doesn't make any significant effort to link to downstream jobs. I've been converting my "pipelines" to monolithic Workflow jobs, and really appreciating the fact that all the actions are more tightly grouped together.
Link from the Workflow project build output to all the corresponding downstream builds.
PR 218 under review as of this writing.
Capture the console output of the downstream jobs and include it in the output of the Workflow job.
