Image Builder places files in /tmp folder and tries to execute them

Question

1. As part of Image hardening we add noexec option to /tmp partition as part of the build step.  
  
2. After that when Imagebuilder runs tests by launching the hardened image it is unable to initiate since it places executable files in /tmp.  
  
Error Message:  
/tmp/**/TaskOrchestratorAndExecutor/bootstrap.sh: Permission denied  
  
Is there a workaround for this ? (we need the noexec option to build a compliant image)

Answer

Found the solution in the docs  
https://docs.aws.amazon.com/imagebuilder/latest/userguide/image-builder-troubleshooting.html  
Solution:  
Possible cause: The /tmp directory is classified as noexec, which can cause Image Builder to fail.  
  
Resolution: Choose a different location to use as the working directory in the workingDirectory field of the image recipe. For more information, see the ImageRecipe data type description.
