Deploying Bridge.Watch

Container Microservices

There are three container microservices deployed on a digital ocean droplet. To build and push the latest changes to the droplet, run:

cd bridge.watch
source ./build_services.sh

Frontend

The frontend is simply built as a static site and all built files as pushed up to the droplet:

cd bridge.watch/react 
npm run build 
scp -r ./public/* root@${digital_ocean_droplet}:/var/www/bridge.watch/html

NGINX Conf

Once the microservices have been rebuilt and pushed, they need to be pulled down and restarted.

ssh root@${digital_ocean_droplet}
cd nbi
docker pull registry.digitalocean.com/${registry}/db-prod:latest
docker pull registry.digitalocean.com/${registry}/express-prod:latest
docker pull registry.digitalocean.com/${registry}/web-prod:latest
docker-compose down -v
docker-compose up -d

Once they have been restarted, the nginx conf needs to be adjusted to use the correct internal IP address.

docker network inspect ${network_name}
[0].Containers["express"].IPv4Address

nano /etc/nginx/sites-available/bridge.watch

Edit this block:

upstream backend {
    server ${express_server}
}

Check config and restart

sudo nginx -t
sudo systemctl restart nginx

How to clear the NGINX Cache

/data/nginx/cache/
rm -rf .
