Single Node MongoDB Instance

Deploy a single instance of MongoDB on Vultr

Deployment Instructions

Go to Vultr and Create a new Startup Script with the code below.

This script will install docker and docker-compose, clone the Mongo Files, set the Mongo Password, and set up reboot logic so Mongo starts up when the node is restarted.

**NOTE: Make sure you replace "ADD PASSWORD HERE" with your Mongo password

#!/bin/sh

snap install docker -y
apt install docker-compose -y

git clone https://github.com/StartupUtils/SingleNodeMongoDB.git

cp -r /tmp/SingleNodeMongoDB /home/
echo "MONGO_PASSWORD=ADD PASSWORD HERE" > /home/SingleNodeMongoDB/.env
cp /home/SingleNodeMongoDB/mongorun.service /etc/systemd/system/mongorun.service

systemctl daemon-reload
systemctl enable mongorun.service
systemctl start mongorun.service

Create an Ubuntu 18.04 Instance

Make sure you select the startup script script you created

Check if Mongo is Running after startup

Sometimes the startup script is not run the first time the server boots up.

SSH into the instance and run the following command.

docker ps

You should see something like this:

CONTAINER ID   IMAGE                         COMMAND                  CREATED        STATUS        PORTS                                           NAMES

If you don't see Containers running, run the following:

bash /tmp/firstboot.exec  

then run check if Mongo is running again:

docker ps 

If it is note running, try to run the following command:

systemctl start mongorun.service

**Note: Once Mongo is running, restart your server to make sure docker starts up when your server is restarted
