Windows CloudFormation 脚本、元数据命令未运行

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:

1. Check if those scripts are getting created on location C:\\cfn\\scripts --IF not then check where is the issue

2. 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.

Answer 3

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:
