User_data scripts have many derivatives depends on operating system, and following do parse the script:
- Linux - uses cloud_init
- Windows 2012 - ec2config
- Windows 2016< - ec2launch
Ec2launch
Configuration file
C:\ProgramData\Amazon\EC2-Windows\Launch\Config\LaunchConfig.json
Log files are in C:\ProgramData\Amazon\EC2-Windows\Launch\Log
*Ec2Launch.txt - the app itself logs *UserDataExecution.txt - contains parsing details and the script output *WallpaperSetup.txt -
Script parsing sections:
<script>cmd://batch commands</script> #always is parsed 1st <powershell></powershell> #2nd <persist>true</persist> #by default is false, true will run on each reboot <runAsLocalSystem></runAsLocalSystem> <powershellArguments></powershellArguments>
Example user_data.tpl script that will initialise 1st attached volume
<powershell> $file = @" select disk 1 attributes disk clear readonly online disk convert mbr create partition primary format quick fs=ntfs label="log" assign letter="d" "@ Set-Content -Path ${env:TEMP}\diskpart -Value $file diskpart.exe /s ${env:TEMP}\diskpart </powershell>
