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
