🎉 Hey Hive Rockstars! 🥳

Ready to level up your tech game, save money, and have some laughs? Grab your favorite beverage, because today we're going on an EPIC ADVENTURE to self-host a MongoDB server—powered by Cloudflare Tunnel! All with pictures, guides, and plenty of emojis! 😁✨

🚦 Prerequisites (a.k.a. What you'll need before liftoff!)

🚀 A domain (Mine: sagarkothari88.one)
☁️ Cloudflare account
🤓 Basic knowledge of Cloudflare Tunnels

Setup MongoDB Server

Okay. Let's get started. You are in for a treat for saving your costs of mongodb by self-hosting it.

🏗️ Step 1: Access Your System

SSH or use Chrome Remote Desktop (I love Chrome Remote Desktop for all my systems!)
Once you're in, you're golden! 🍀

🐳 Step 2: Install Docker

Pro-tip: Docker is like giving your MongoDB its personal luxury apartment.

For Ubuntu users — just like me! — here's the cheat code:
You can follow the official Docker docs:
Feeling lucky? Use my ready-to-copy commands below!

🎯 Docker-install-step-1: Remove any old baggage

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

🎯 Docker-install-step-2: Add Docker’s home to your address book

sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc
echo 
“deb arch=$(dpkg –print-architecture) signed-by=/etc/apt/keyrings/docker.asc https://download.docker.com/linux/ubuntu 
$(. /etc/os-release && echo “${UBUNTU_CODENAME:-$VERSION_CODENAME}”) stable” | 
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

🎯 Docker-install-step-3: Give Docker the keys!

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

🍃 Step 3: Spin Up MongoDB in Docker!

Ready? Set. GO! Swap out the username & password, then run:

sudo docker run -d \
  --name mongodb_custom \
  -p 27017:27017 \
  -e MONGO_INITDB_ROOT_USERNAME="your-mongo-db-super-admin-username-here" \
  -e MONGO_INITDB_ROOT_PASSWORD="your-mongo-db-super-admin-password-here" \
  mongo:latest

Congratulations! 🥳 Your private MongoDB server is now live.

🌩️ Setting up Cloudflare Tunnel (where security meets cool tech)

Setting up cloudflare

Wanna access your MongoDB from ANYWHERE but keep it ultra-secure? You need a Cloudflare Tunnel! 🚇🦸‍♂️

Zero Trust Magic

Open Cloudflare dashboard
Click Zero Trust (trust me, click it!)

Open Cloudflare Dashboard & click on Zero Trust

Tunnels Time!

Go to Network > Tunnels

Access Tunnel

Create a Tunnel—just like creating a secret passage!

Create a new tunnel

Give your Tunnel a cool name (I called mine `"mongodb"`)

Name your tunnel

Follow setup instructions for Ubuntu

Setup tunnel on your ubuntu

Once you see:

2025-08-03T12:32:03Z INF Using Systemd
2025-08-03T12:32:05Z INF Linux service for cloudflared installed successfully

celebrate! Your tunnel is ready 🥳

Final Step: Bind your tunnel like a pro

Bind to tcp://localhost:27017 (VERY IMPORTANT!)
Click ‘Complete setup’

Last step for cloudflare tunnel

Voilà! Your MongoDB server is world-ready, but only accessible to your secure, trusted peers. (Intruders = Bye Felicia! 👋🚫)

📨 Connecting with MongoDB Client (the fun continues!)

Time to connect to your shiny new MongoDB from another system (“mongodb-client” aka party guest system).

🔧 Install Cloudflared on the Client

For macOS users

brew install cloudflared

or you can use macPorts

sudo port install cloudflared

For Ubuntu adventurers

Add GPG & Repo:

sudo apt install curl lsb-release
curl -L https://pkg.cloudflare.com/cloudflare-main.gpg | sudo tee /usr/share/keyrings/cloudflare-archive-keyring.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/cloudflare-archive-keyring.gpg] https://pkg.cloudflare.com/cloudflared $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/cloudflared.list

Install:

sudo apt update
sudo apt install cloudflared

🛡️ Login Cloudflared

cloudflared tunnel login

This opens a browser 👨‍💻
Log into Cloudflare & authorize your domain. (Mine: sagarkothari88.one)

🌉 Start Bridge!

cloudflared access tcp --hostname mongodb.sagarkothari88.one --url localhost:27017

Bridge created! Your remote server is now accessible safely as localhost.

🥞 Connect with MongoDB!

For NodeJS:
mongodb://admin-user:admin-password@localhost:27017/
To test: use MongoDB Compass, start the bridge FIRST, then connect.

connect using compass

Whoa! You did it! 🎊 Your own self-hosted MongoDB — secure, portable, AND budget-friendly.

💬 Wrapping Up

Thanks for joining this fun ride 💙
More power to the Hive Blockchain 🐝
More power to all our community members 🙌
Until next time, Happy Coding! 💻✨
