How do I prevent two pipeline jenkins jobs of the same type to run in parallel on the same node?

Question

I do not want to allow two jobs of the same type (same repository) to run in parallel on the same node.

How can I do this using groovy inside Jenkinsfile ?

Answer 1

I think there are more than just one approach to this problem.

Pipeline

• Use latest version of Lockable Resources Plugin and its lock step, as suggested in other answer.
• If building the same project:
  • Uncheck Execute concurrent builds if necessary.
• If building different projects:
  • Set different node or label for each project.

Jenkins

• Limit number of node's executors to 1?

Plug-ins

• Build Blocker Plugin - supposedly supports Pipeline projects
• Throttle Concurrent Builds Plugin - not compatible with Pipeline projects
