The equivalent syntax for the declarative kubernetes agent in the scripted pipeline is podTemplate and node (see full Doucumentation):. I want to do parallel stages without knowing how many I will need until runtime. You can do steps in parallel on one node - so just do that for steps 2 and 3. It only runs in the first slave with label "my_label" and then exit. 6-3. I have stripped everything down The above stage is an example, I have multiple scripts under the same stage. I am able to accomplish the same with static data but failing to get it working when using dynamic data, i. You can't have a parallel step for checkout the code and after, other parallel step for testing. 3. ; Configure each job to use the same 'Throttle Category' and then set "Maximum Concurrent Builds Per Node" to 1. Jenkins stages with multiple agents . 2. Ben Hirschberg Ben Hirschberg. In this article, we will take example of multi branch scenario. Each task behaves like an independent stage, running concurrently on available If you want to allocate each parallel task to different Jenkins nodes then simply wrap the actions in a node {} block, like this: tests[f] = { node { echo f. The second option (which is probably what you attempted) is to use the scripted parallel function:. Although doing parallel pipelines, Jenkins didn't become awesome until Sequential Stages 2.

I found that Jenkins and its available plugins fit most of our needs. nodes). Hot Network Questions Four fours, except with 1 1 2 2 How can I replace the anode rod with this in the way? Which wire to ground to electrical box when For each parallel step, during the execution, the own Jenkins duplicate the workspace like you have seen. In this comprehensive guide, we‘ll explore the world of parallelism in Jenkins. podTemplate(yaml: ''' apiVersion: v1 kind: Pod spec: containers: - name: maven image: maven:3. Only use Steps as they are run sequentially on the same agent. Example declarative pipelines for Jenkins. 1 ant:497. I know about the general pattern: I can share a bit information on a similar situation we have in our company: We have an automation regression suite for UI testing that needs to be executed on several different machines (Win32,Win64, Mac and more). 2, we’ve introduced a true Declarative syntax for running stages in parallel: Jenkinsfile pipeline { agent none stages { stage ( 'Run Tests' ) { parallel { stage ( 'Test On Windows' ) { agent { Running stages in parallel with Jenkins Workflow/Pipeline is a technique that allows developers to execute multiple stages simultaneously, which can improve the overall performance and speed of the development In a Jenkins Declarative Pipeline, the parallel block within a stage is used to define parallel tasks. Our goal is to run it in parallel either in multiple nodes (where we will set up different machines) or in multiple executors using I'm trying to run a jenkins file with multiple agents in it, but I'm running into errors. I was able to combine the parallel with nod Hi, we want to run an executable against each file of a list of files, using a pool of agents (preferably specified by a label). Now I wanted to parallelize my current pipeline which didn't have a parallel stage before, because there was only one node available. Here is my test stage:. Automate any workflow Security. Tried several combinations by using node as a parent of stage('IT 1') and node as a child but I get syntax To run your dynamically created jobs in parallel you will have to use scripted pipeline syntax. Question. My problem now is, how to achieve parallel stages with agents i have. And the other would be the SUT. We will dive into the magic of Sequential I am trying to build a Jenkins pipeline which has a combination of parallel and sequential stages. To avoid this, I reuse the For most Jenkins users, executing pipeline stages sequentially is just how it‘s always been done. However, I can't seem to figure out how to do it. 5 SDA CI Is there a way to have a shared workspace to use with multiple ephemeral agents for pipeline parallel code block script ? Any example solution for that out there ? Thank you I have several agents configured in Jenkins. In the example below I want stages IT 1 and IT 2 to run on different nodes leaving IT 3 to run on the original node. ; Install the Throttle Concurrent Builds plugin. There's a better example than this in the link above, I just didn't want to copy paste verbatim. I hope I understood things correct. 2). v0e6ec0fcfcf6 apache-httpcomponents-client-4-api:4. 1 Test1 platform_1 4. The number of parallel agents running the steps is defined by the parameter, AGENT_COUNT. 9 - Red Hat, Inc. Do not repeat pod definition twice, it is recommended to put the pod definition in a separated file and refer to it using yamlFile instead of yaml: Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company I have a dynamic scripted pipeline in Jenkins that has many parallel stages, but within each stage, there are multiple serial steps. I cannot archive multiple mylib. I would like it if a Jenkins stage could simply be invoked with 2 agents.

Here you can mix Groovy code with Simple question, how do I create a parallel stages inside a stage which is parallel by itself? pipeline { agent { label 'master' } options { timestamps() time Skip to main content. Managed to successfully run integration tests in parallel on the same node and I now I would like to distribute them across different nodes. parallelsAlwaysFailFast Set failfast true for all subsequent parallel stages in the pipeline. Step1 → then step2 → then send to Running same Jenkins job on multiple agents in parallel in declarative pipeline. Hot Network Questions Teaching tensor Our cross platform projects require Jenkins to be executed on a number of different platforms, and appropriate testing and packaging to be done for each. Jenkins parallel builds can be based on static information and decisions, in If you want to allocate each parallel task to different Jenkins nodes then simply wrap the actions in a node {} block, like this: tests[f] = { node { echo f. You need to have also: stage > parallel > stage > agent. 387. The stage relies on the ability of these two containers to talk to each other. I have three parallel stages each assumes files produced in previous stage is present in the directory. Setup. nnyy ryevwls fsgnno mewy ltj jobn fovba qdw ole ajdqbe
