There is a method to setup an EC2 machine to execute Kafka starting script on startup? I use also java Aws SDK, so I accept both solution for a program java that run command on EC2 instance and solutions for a bash script mode that run kafka script at startup.
A script can be passed in the User Data property.
If you are using the Amazon Linux AMI, and the first line of the script begins with #!, then the script will be executed the first time that the instance is started.
For details, see: Running Commands on Your Linux Instance at Launch
What is the OS of EC2 instance?
You could use userdata script at instance launch time. Remember this is just 1time activity
If your requirement is to start the script everytime you reboot EC2 instance then you could make use of
rc.localfile on Linux instances which is loaded at OS boot time.
If you are running a windows EC2 you'll want to read: https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/ec2-windows-user-data.html
Example:
<script>
echo Current date and time >> %SystemRoot%\Temp\test.log
echo %DATE% %TIME% >> %SystemRoot%\Temp\test.log
</script>
