Pipeline supports two syntaxes, Declarative (introduced in Pipeline 2.5) and Scripted Pipeline *** Pipeline Vocabulary: Steps, Nodes, and Stages - A step, also known as a "build step", is a single task that we want Jenkins to execute.

  • A "node", within the contexts of a pipeline, refers to a step that does two things.

First, it schedules the defined steps so that it'll run as soon as an executor is available. Second, it creates a temporary workspace which is removed once all steps have completed.

  • And lastly, we have "Stages". Stages are for setting up logical divisions within pipelines. The Jenkins Pipeline visualization plugin will display each stage as a separate segment. Because of this, teams tend to name stages for each phase of the development process, such as "Dev, Test, Stage, and Production". *** Jenkins pipeline is durable from Jenkins master restart #+BEGIN_EXAMPLE
  • One huge benefit of using a pipeline is that the job itself is durable. A Pipeline job is able to survive planned or even unplanned restarts of the Jenkins master. If you need to survive slave failures as well, you'll have to use checkpoints.

  • Unfortunately, the checkpoints plugin is only available for the enterprise edition of Jenkins. Pipelines are also pausable.

Stefan Jansson [4:49 PM] the jenkins-plugin is called build monitor plugin:

[4:50] a competitor is radiator: - i'd use radiator once getting over a certain amount of jobs to monitor, since it has an option to only display failing jobs

[4:54] You could even call it "continuous testing in production" to make it an even stronger trend buzzword... "continuous testing" and "testing in production" are buzzwords that traditional testers do shrug from, but something I believe strongly in for the future, for devops teams, and teams running a continuous delivery process, and bigger organisations where you depend on other teams/products

Denny Zhang [4:54 PM] Yes, we have Jenkins monitor plugin enabled

[4:55] Don't quite understand its value though

Stefan Jansson [4:57 PM] what is it that you don't understand?

Denny Zhang [4:57 PM] It gives me an overview. But what I can get from it?

new messages Stefan Jansson [5:05 PM] my example works like an extra layer of monitoring, to discover even faster if you got a problem in production, if your data-logging, alarms etc might not be as fast with, or as obvious.. it won't even catch everything, that a test can.

for example, my teams builds a booking-flow for the nordics biggest travel-company.. if you cannot book a seat on a plane, simply because an API somewhere doesn't respond, or are having slow timeouts so it doesn't even display the option for the customer... the error-code monitoring and larms might go up, but it takes a while until the larms sets off, or that the error count get's to a suspicious amount so that you take a look at it.. but the TEST that runs making a booking, will fail immidiatly and give you a RED-flag on the monitor ** TODO Jenkins SCM Sync configuration plugin *** SCM Sync configuration plugin *** jenkinsfile: groovy script *** Manage Jenkins Jobs with YAML ** TODO configure pipeline status in a better way ** TODO jenkins pipeline: can't abort it ** TODO Jenkins group stage: 5 groups Romain B.

Denny Zhang (Github . Blogger) [10:43 AM] Let's say above 2 Jenkins instances serve the service.

As we know Jenkins have local $JENKINS_HOME folder.

So how these 2 instances work together to serve HA?

Any thoughts? @Pradipta Dash @Stefan Jansson (QA in Continuous Delivery) @Jonathan.McAllister @Keef Baker

Jonathan McAllister [10:43 AM] joined #jenkins by invitation from Denny Zhang (Github . Blogger).

Philip Schwartz [11:20 AM] @Denny Zhang (Github . Blogger) are those suppose to be 2 jenkins masters running in ecs with a load balancer infront of them?

Denny Zhang (Github . Blogger) [11:20 AM] yes

Philip Schwartz [11:20 AM] Jenkins doesn't work that way. You can't drop a load balance infront of masters as they don't cross communicate

[11:22] If they are cloudbees instances you can use the HA plugin to allow promotion on single master failure. But it is still not the same and requires shared file systems between them

Denny Zhang (Github . Blogger) [11:22 AM] How we can avoid Jenkins SPOF, Philip?

*** TODO Jenkins HA


Puneeth [12:48 PM] @Denny Zhang (Github . Blogger) jenkins master HA is essentially jenkins master in an asg with efs volume for jenkins home

[12:49] @Denny Zhang (Github . Blogger) there is a white paper from aws on jenkins HA

[12:49] jenkins slaves ha is again via asg and spot fleet

[12:49] at least that's our approach

Puneeth [12:54 PM] @Denny Zhang (Github . Blogger) there can only be one master unless unless unless you move the main job queues from the jenkins master. and use an external job queue :) In this case there can be multi master jenkins confg spread across many regions or within the same region. this is a super advanced approach. this approach is used by openstack . we used it too in our previous company

Please Note that "Filter merge request by label" is optional. If you add any label, this job will be triggered only when the MR contains these labels Generate Secret toke by clicking "Generate" button. (Please make note of the token, we need to enter same value in the GitLab hook in Step 3) Configure your Pipeline job location. (Jenkins Job will scan the git-repo that you configure for "Jenkinsfile" file)

Credentials : You can use whoever have atleast "developer" permission on this project. Branches to build: "${gitlabSourceRepoName}/${gitlabSourceBranch}" Script path: This is the path to the Jenkinsfile in your repo. Save your pipeline job. Now, its time to configure the webhook in GitLab repo to trigger this job on MR. Go to your repo in GitLab → Settings → Integrations

Enter the token that you generated in your Jenkins pipeline job and enable all appropriate checkboxes for your project. Add GitLab logger in Jenkins Go to Jenkins -> Manage Jenkins -> System Log Add new log recorder Enter 'Gitlab plugin' or whatever you want for the name On the next page, enter 'com.dabsquared.gitlabjenkins' for Logger, set log level to FINEST, and save Then click on your Gitlab plugin log, click 'Clear this log' if necessary, and then use GitLab to trigger some actions Refresh the log page and you should see output Go back to the Integration page in the GitLab, click on "Test" button to see if your webhook is triggering the Jenkins job. you can just see the log in the Jenkins under the logger you just created in previous step Send a Dummy MR to the branch (Make sure you add the "labels" if you enabled any filtering in your job) and see if the pipeline is getting triggered, if not, check the logs in the Jenkins and Gitlab (by editing the hook, you can see the Recent Deliveries) More info: More info on writing pipeline stages with GitLab:
