Can we run parallel builds in Jenkins?

Can we run parallel builds in Jenkins?

Jenkins allows for parallel execution of builds for a Job. Job configuration page has a check box, “Execute concurrent builds if necessary”. Also, in the master node configuration set the “# of executors” field to more than 1. Once these two are done, parallel job execution is enabled.

What are stages in Jenkins pipeline?

Stage. A stage block defines a conceptually distinct subset of tasks performed through the entire Pipeline (e.g. “Build”, “Test” and “Deploy” stages), which is used by many plugins to visualize or present Jenkins Pipeline status/progress.

How do I run multiple jobs in Jenkins?

Use mulijob in the following way:

1. When creating new Jenkins jobs you will have an option to create MultiJob project.
2. In the build section, this job can define phases that contain one or more jobs.
3. All jobs that belong to one phase will be executed in parallel (if there are enough executors on the node)

How do you do parallel builds in Jenkins?

Can a stage be run in parallel in declarative pipeline?

You can now specify either steps or parallel for a stage, and within parallel, you can specify a list of stage directives to run in parallel, with all the configuration you’re used to for a stage in Declarative Pipeline. We think this will be really useful for cross-platform builds and testing, as an example.

Why are parallel stages not allowed in Jenkins?

Stashing and unstashing between each single stage causes overhead. I would rather have all stages until the manual input executed in a single workspace. But agent is only allowed in stages that contain steps. Each parallel stage blocks a single agent. So if there is only one free agent, there is no parallel execution, unlike before.

How to define multiple levels of parallel stages?

I need to define a declarative pipeline with multiple levels of parallel stages as such: First, 1 should run, then 2 should run, then all of 3.x should run in parallel and when 3.1 is done all 4.x should run in parallel. It doesn’t seem possible for two reasons: 1.

Why are parallel stages running on the same agent?

Each parallel stage blocks a single agent. So if there is only one free agent, there is no parallel execution, unlike before. I can live with (1) if it’s not possible otherwise, but parallel execution on one agent is important for me.
