Windows CloudFormation Script, MetaData commands are not running - windows

Question

Below is my CloudFormation template for creating a windows EC2 instance with Java and Tomcat installed on it. However, the nothing from the MetaData is being executed. I login to the created EC2 instance, and none of the specified folders in the metadata can be found. What is my CloudFormation script missing?
Thank you

Answer 1

There are 2 things you need to check:
Check if those scripts are getting created on location C:\cfn\scripts
--IF not then check where is the issue
If these scripts are created there, then call separately the step "commands" in configSets (line no. 33-34). I suspect that is the problem where the actual scripts are not getting called.

Answer 2

Instead of using "setup" block, try something like this. This is how I have been using.

Super old... but anywho!
cfn-init is never called. Typically this will be done once via UserData
UserData:
Fn::Base64:
!Sub |
<PowerShell>
cfn-init.exe -v -s ${AWS::StackName} -r <resourceref> --configsets MyConfigSet --region ${AWS::Region}
</PowerShell>
Then within your init you'd also configure the cfn-hup service to monitor a couple configuration files.
AWS::CloudFormation::Init:
configSets:
MyConfigSet:
- configureCfn
configureCfn:
files:
c:\\cfn\\cfn-hup.conf:
content: !Sub |
[main]
stack=${AWS::StackName}
region=${AWS::Region}
c:\\cfn\\hooks.d\\cfn-auto-reloader.conf:
content: !Sub |
[cfn-auto-reloader-hook]
triggers=post.update
path=Resources.UiPathRobot.Metadata.AWS::CloudFormation::Init
action=cfn-init.exe -v -s ${AWS::StackName} -r <resourceref> --configsets MyConfigSet --region ${AWS::Region}
services:
windows:
cfn-hup:
enabled: true
ensureRunning: true
files:
- c:\cfn\cfn-hup.conf
- c:\cfn\hook.d\cfn-auto-reloader.conf
