Here’s another way to add startup scripts to your instance during creation.
UserData:
Fn::Base64: !Sub |
#cloud-config
repo_upgrade: none
runcmd:
# Cloud init startup script
- "bash /root/setup.sh"
write_files:
# Cloud init startup script
- owner: root:root
permissions: '0644'
path: /root/setup.sh
content: |
#! /bin/bash -x
write_files:
# Cloud init startup script
- owner: root:root
permissions: '0644'
path: /root/setup.sh
content: |
#! /bin/bash -x
# run your bash commands here
date > log.txt
uptime >> log.txt |
The above script creates a file setup.sh and executes it during instance creation. The output is dumped to log.txt file.
