docker-compose install

• apt update to bring current packages to server
• apt install to add docker requirements on server
• usermod to allow docker commands without sudo
• reboot EC2 after these steps

sudo apt update
sudo apt install docker-compose -y
sudo usermod -aG docker ${USER}

clone github repo

• git to obtain a local copy of project

$ git clone https://github.com/Trystan-Schmits/Multiplayer.git

start server

• cd to navigate to server directory
• cp to have default docker-compose.yml in directory
• docker-compose to build and run websocket application
• docker to validate process

cd /home/ubuntu/Multiplayer/node_backend
cp Docker-compose.yml  docker-compose.yml
docker-compose up -d --build
docker ps

internet access for websocket server

setup domain

use AWS route 53 to domain authority

• match nginx server_name for Record name
• match public IP from EC2 server for Value

Record name: platformer.nighthawkcodingsociety.com
Record type: A
Value: 18.220.83.242
Alias: No
TTL (seconds): 300
Routing policy: Simple

install nginx

use nginx as reverse proxy service

• apt install to add nginx service

sudo apt install nginx

install certbot

use certbot as certificate authority for https

• snap install core to add snap package manager
• snap install to add certbot serverice

sudo snap install core; sudo snap refresh core
sudo snap install --classic certbot

setup reverse proxy configuration file

• use editor like nano platformer or vi platformer to make reverse proxy configuration
• copy and paste template below into file
• match route 53 Record name for server_name
• match docker-compose exposed port of proxy_pass port
• save file and exit

server {
    server_name platformer.nighthawkcodingsociety.com;

    location / {
        proxy_pass http://localhost:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

activate nginx

activate platformer configuration and sign

• ln makes nginx platformer configuration active
• certbot applies https certificate to nginx server_name

sudo ln -s /etc/nginx/sites-available/platformer /etc/nginx/sites-enabled/
sudo certbot --nginx

docker-compose update

the steps to update are focussed on stopping, updating, and rebuilding node backend service

• cd navigates to node_backend source
• pull updates project to lates
• docker-compose down stops service
• docker-compose build forces rebuild of node_backend
• docker-compose up starts service

cd ~/Multiplayer/node_backend
git pull
docker-compose down
docker-compose build --no-cache
docker-compose up -d
