I have a pipeline job running in Jenkins and I want to know the name of the node it's running on. Is there a way to get the node name from within the job's Groovy script?
I have tried the below code:
print currentBuild.getBuiltOn().getNodeName() the error is:
org.jenkinsci.plugins.scriptsecurity.sandbox.RejectedAccessException: unclassified method org.jenkinsci.plugins.workflow.job.WorkflowRun getBuiltOn I also tried this:
def build = currentBuild.build() print build.getExecutor().getOwner().getNode().getNodeName() but the result is ''.

As part of the terminology cleanup effort, the built-in node was renamed from "master node" to "built-in node" in Jenkins 2.307 and in Jenkins 2.319.
Click on Manage Jenkins in the left corner on the Jenkins dashboard. Click on Manage Nodes. Select New Node and enter the name of the node in the Node Name field.
When creating a new slave node, Jenkins allows us to tag a slave node with a label. Labels represent a way of naming one or more slaves. We leverage this labeling system to tie the execution of a job directly to one or more slave nodes.
By default, Jenkins employs the algorithm known as consistent hashing to make this decision. More specifically, it hashes the name of the node, in numbers proportional to the number of available executors, then hashes the job name to create a probe point for the consistent hash.
There is an environment variable 'NODE_NAME' which has this.
You can access it like this:
echo "NODE_NAME = ${env.NODE_NAME}" When you are editing a pipeline job, you can find all the available environment variables by going to the "pipeline syntax" help link (left of page) then look for the "Global Variables" section and click through to the "Global Variables Reference". There is a section "env" that lists the environment variables available.
