Scenario

Let's say that you have an issue on a given Jenkins agent at a given time, but you don't know which build can cause it. Here is how to find out which builds where running on that agent, at that time.

In this case, the agent is an AWS EC2 VM, with a well known instance ID (in this case, i-02d41abc1a375089d).

This works with Jenkins organization folders.

1. find all builds executed on the agent

Set of commands which are useful to clean after yourself when I tried to delete AWS Cloud Formation stacks when my infrasec role did not had all the needed permissions.

List stacks which can be deleted (DELETE_FAILED status):

aws cloudformation list-stacks | jq '.StackSummaries[] | select(.StackStatus=="DELETE_FAILED") | .StackName'

OR

List stacks which contain a specific string in their name:

aws cloudformation list-stacks | jq '.StackSummaries[] | select(.StackName | contains("bcol")) | .StackName'

Delete offline nodes

for (aSlave in hudson.model.Hudson.instance.slaves) {
    if (aSlave.getComputer().isOffline()) {
        aSlave.getComputer().setTemporarilyOffline(true,null);
        aSlave.getComputer().doDoDelete();
    }

Use case: when I go to specific AWS region, I want the UI to be styled differently (color). Avoids goofing in some places.

Install Stylus chrome extension https://add0n.com/stylus.html
Install this style: https://userstyles.org/styles/150583/aws-navbar-color-by-region

This can be tweaked / modified:

@-moz-document domain(us-east-1.console.aws.amazon.com)
{

	import base64
	import urllib
	#import tlslite
	from tlslite.utils import keyfactory
	import oauth2 as oauth

	class SignatureMethod_RSA_SHA1(oauth.SignatureMethod):
	name = 'RSA-SHA1'

	def signing_base(self, request, consumer, token):

	This CLI will convert a PEM private key from a GitHub app, so that it can be used in Jenkins, to eventually be injected in K8s values file

	```
	sed ':a;N;$!ba;s/\n/\\\\\\\\n/g' certificate.private-key.pem
