# Unresponsive node cleanup for Puppet Enterprise 2016.2 | |
# | |
# When our system scales down, we often have many unresponsive nodes. These | |
# nodes count towards our overall license count. Future scaling events will | |
# keep stacking these unused licenses. This is a simple method to purge the | |
# unresponsive nodes. | |
# | |
# This script can be run periodically on the puppet master to clean up | |
# unresponsive nodes. | |
# | |
# To access the puppet api from the command line, you'll need to generate an | |
# access token. In puppet console, create a user who is part of the admin | |
# group. Follow this to create a token. | |
# https://docs.puppet.com/pe/latest/rbac_token_auth.html#setting-a-token-specific-lifetime | |
# $ puppet-access login --lifetime 0 | |
# Location for Ubuntu 14.04.5 LTS | |
token = `cat /home/ubuntu/.puppetlabs/token` | |
# query used to determine unresponive nodes (nodes that haven't reported in | |
# over an hour. using 2 hours.) | |
query = ["<", "report_timestamp", (Time.now - 7200).utc.iso8601].to_json | |
url = "http://localhost:8080/pdb/query/v4/nodes?query=#{query}" | |
# | |
response = HTTParty.get(url, headers: {"X-Authentication" => token}, verify: false) | |
# unresponsvie node certs | |
certs = response.collect{|x| x["certname"]} | |
# https://docs.puppet.com/pe/latest/node_deactivation.html | |
puts "purging old node certs..." | |
result = false | |
certs.each do |cert| | |
# returns true if successfully executed | |
result = system( "sudo puppet node purge #{cert}") | |
end | |
# if we purged nodes, we'll need to run puppet agent and restart puppet server | |
if result | |
puts "run puppet agent..." | |
system( "sudo puppet agent -t" ) | |
puts "restart puppet server...(this may take a few minutes)" | |
system( "sudo service pe-puppetserver restart" ) | |
else | |
puts "no unresponsive nodes" | |
end | |
puts "done!" |
