[CSHieuV]

Description of Changes:

Code to create Bootstrap container to run on a Bottlerocket host.

Testing Done:

• A user can create the Bottlerocket instance and validate that changes specified in the user script have been applied successfully

Some user data used for testing can be seen below:

#!/usr/bin/env sh
set -euo pipefail
# Create the directory
mkdir -p /var/lib/my_directory
# Set API client configurations
apiclient set --json '{"settings": {"oci-defaults": {"resource-limits": {"max-open-files": {"soft-limit": 4294967296, "hard-limit": 8589934592}}}}}'
# Load kernel module
if command -v modprobe > /dev/null 2>&1; then
  modprobe dummy
fi
echo "User-data script executed."
