Musare

MusareNode

This is a rewrite of the original Musare in NodeJS, Express, SocketIO and VueJS. Everything is ran in it's own docker container.

Our Stack

• NodeJS
• MongoDB
• Redis
• Nginx
• VueJS

Frontend

The frontend is a vue-cli generated, vue-loader single page app, that's served over Nginx. The Nginx server not only serves the frontend, but also serves as a load balancer for requests going to the backend.

Backend

The backend is a scalable NodeJS / Redis / MongoDB app. Each backend server handles a group of SocketIO connections. User sessions are stored in a central Redis server. All data is stored in a central MongoDB server. The Redis and MongoDB servers are replicated to several secondary nodes, which can become the primary node if the current primary node goes down.

Requirements

• Docker

Getting Started

Once you've installed the required tools:

1. git clone https://github.com/MusareNode/MusareNode.git

2. cd MusareNode

3. cp backend/config/template.json backend/config/default.json

The secret key can be whatever. It's used by express's session module. The apis.youtube.key value can be obtained by setting up a YouTube API Key.

1. Build the backend and frontend Docker images

docker-compose build

1. Start the databases and tools in the background, as we usually don't need to monitor these for errors

docker-compose up -d mongo mongoclient redis

1. Start the backend and frontend in the foreground, so we can watch for errors during development

docker-compose up backend frontend

1. You should now be able to begin development! The backend is auto reloaded when you make changes and the frontend is auto compiled and live reloaded by webpack when you make changes. You should be able to access Musare in your local browser at http://<docker-machine-ip>:8080/ where <docker-machine-ip> can be found below:

   • Docker for Windows / Mac: This is just localhost

   • Docker ToolBox: The output of docker-machine ip default

Extra

Below is a list of helpful tips / solutions we've collected while developing MusareNode.

Mounting a non-standard directory in Docker Toolbox on Windows

Docker Toolbox usually only gives VirtualBox access to C:/Users of your local machine. So if your code is located elsewere on your machine, you'll need to tell Docker Toolbox how to find it. You can use variations of the following commands to give Docker Toolbox access to those files.

1. First lets ensure the machine isn't running

docker-machine stop default

1. Next we'll want to tell the machine about the folder we want to share.

"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" sharedfolder add default --name "d/Projects/MusareNode" --hostpath "D:\Projects\MusareNode" --automount

1. Now start the machine back up and ssh into it

docker-machine start default && docker-machine ssh default

1. Tell boot2docker to mount our volume at startup, by appending to its startup script

   sudo tee -a /mnt/sda1/var/lib/boot2docker/profile >/dev/null <<EOF
   
   mkdir -p /d/Projects/MusareNode
   mount -t vboxsf -o uid=1000,gid=50 d/Projects/MusareNode /d/Projects/MusareNode
   EOF

1. Restart the docker machine so that it uses the new shared folder

docker-machine restart default

1. You should now be good to go!

Fixing the "couldn't connect to docker daemon" error

Some people have had issues while trying to execute the docker-compose command. To fix this, you will have to run docker-machine env default. This command will print various variables. At the bottom, it will say something similar to @FOR /f "tokens=*" %i IN ('docker-machine env default') DO @%i. Run this command in your shell. You will have to do this command for every shell you want to run docker-compose in, every session.
