Create a new instance, select Ubuntu 24.04, Instance type as t1.small (or the size which suits you) and add script to the user data section, click launch!

Here is the 'user data' script you can use

#!/bin/bash

# This is a basic setup intended for development purposes.

# Update package list and install required packages.
apt update > /dev/null 2>&1
apt-get install -y gnupg curl ufw

# Setup MongoDB repository.
curl -fsSL https://www.mongodb.org/static/pgp/server-8.0.asc | gpg -o /usr/share/keyrings/mongodb-server-8.0.gpg --dearmor
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-8.0.gpg ] https://repo.mongodb.org/apt/ubuntu $(grep '^UBUNTU_CODENAME=' /etc/os-release | cut -d'=' -f2)/mongodb-org/8.0 multiverse" | tee /etc/apt/sources.list.d/mongodb-org-8.0.list

apt update > /dev/null 2>&1
apt-get install -y mongodb-org

# Configure MongoDB to listen on all interfaces and enable authorization.
sed -i "s/bindIp: 127.0.0.1/bindIp: 0.0.0.0/g" /etc/mongod.conf
sed -i "s/#security:/security:\n  authorization: enabled/g" /etc/mongod.conf

systemctl daemon-reload
systemctl start mongod
systemctl enable mongod

# Wait for MongoDB service to be ready (max 30 seconds).
for i in {1..30}; do
  if mongosh --eval "db.adminCommand('ping')" >/dev/null 2>&1; then
    echo "MongoDB is ready"
    break
  fi
  sleep 1
done

# Create admin user.
# Replace 'PleaseChangeYourPassword' with your actual secure password once the installation is completed.
MONGODB_USERNAME="admin"
MONGODB_PASSWORD="PleaseChangeYourPassword"
mongosh --eval "db.getSiblingDB('admin').createUser({user: '$MONGODB_USERNAME', pwd: '$MONGODB_PASSWORD', roles: [ { role: 'userAdminAnyDatabase', db: 'admin' }, 'readWriteAnyDatabase' ]})"

# Enable UFW if it's inactive.
if ufw status | grep -iq "inactive"; then
    echo "y" | ufw enable
fi

# Allow incoming TCP connections on MongoDB port (27017) and SSH (22).
ufw allow 27017/tcp
ufw allow 22/tcp
ufw reload

Once your instance is up and running, You can assign a public IP to it and SSH to it .Make sure you have inbound rules defined to allow SSH for the instance and open port for Mongo in the Security Group assigned to your VM.

Associate Public IP
Allow inbound rule for SSH and Mongo

First things first. Let's change the password for Mongo. SSH to your VM and run following command with current password.

mongosh -u admin -p 'PleaseChangeYourPassword' --authenticationDatabase admin

Now switch to admin database and run password change command. Replace 'newSecurePassword' with a strong password.

use admin
db.changeUserPassword("admin", "newSecurePassword")
Change Mongod password

Finally, you may want to connect through Mongodb Compass or Studio 3T

use the following format to connect to mongo. Replace PASSWORD and IP accordingly

mongodb://admin:PASSWORD@IP:27017/?authSource=admin
