Add sudo commands to init script through user data

Hello Geeks I’m trying to create an init script for my droplet creation. So I’m setting Droplet meta data using User Data feature. I successfully install git and added new non root sudo user to the system. But when I try to install docker it’s not getting installed. My guess is because it’s a sudo command. Below is my script.

#!/bin/bash
set -euo pipefail

USERNAME=test

COPY_AUTHORIZED_KEYS_FROM_ROOT=true

OTHER_PUBLIC_KEYS_TO_ADD=()

useradd --create-home --shell "/bin/bash" --groups sudo "${USERNAME}"
usermod -aG sudo "${USERNAME}"

encrypted_root_pw="$(grep root /etc/shadow | cut --delimiter=: --fields=2)"

if [ "${encrypted_root_pw}" != "*" ]; then
    echo "${USERNAME}:${encrypted_root_pw}" | chpasswd --encrypted
    passwd --lock root
else
    passwd --delete "${USERNAME}"
fi

chage --lastday 0 "${USERNAME}"

home_directory="$(eval echo ~${USERNAME})"
mkdir --parents "${home_directory}/.ssh"

if [ "${COPY_AUTHORIZED_KEYS_FROM_ROOT}" = true ]; then
    cp /root/.ssh/authorized_keys "${home_directory}/.ssh"
fi

for pub_key in "${OTHER_PUBLIC_KEYS_TO_ADD[@]}"; do
    echo "${pub_key}" >> "${home_directory}/.ssh/authorized_keys"
done

chmod 0700 "${home_directory}/.ssh"
chmod 0600 "${home_directory}/.ssh/authorized_keys"
chown --recursive "${USERNAME}":"${USERNAME}" "${home_directory}/.ssh"

sed --in-place 's/^PermitRootLogin.*/PermitRootLogin prohibit-password/g' /etc/ssh/sshd_config
if sshd -t -q; then
    systemctl restart sshd
fi
