Question

Is there any way I can extract node labels from jenkins API? The standard:

{base_url}/computer/{node}/api

did not seem to have any label information. Is it in some other place?

Answer 1

Apparently, node labels are part of node configuration, so they live in

{base_url}/computer/{node_str}/config.xml

Here is my hack to access that through python jenkinsapi (similar to job configuration), from node_str

import xml.etree.ElementTree as ET
from jenkinsapi.jenkins import Jenkins

j = Jenkins(...)
n = j.get_node(node_str)
response = n.jenkins.requester.get_and_confirm_status( "%(baseurl)s/config.xml" % n.__dict__)
_element_tree = ET.fromstring(response.text)
node_labels = _element_tree.find('label').text
