2. docker exec postgres -it /bin/bash
3. su -u postgres e psql
4. CREATE DATABASE myapp;
5. CREATE USER rocketseat WITH ENCRYPTED PASSWORD 'uBaPt2H4rJTp8T59';
6. GRANT ALL PRIVILEGES ON DATABASE myapp TO rocketseat;

Configuração da aplicação

1. Clone Masterclass SQL
2. Configurar script "start": "node src/server.js"
3. Testar aplicação
4. Configurar dotenv

NODE_ENV=development
PORT=3333

DB_HOST=localhost
DB_NAME=sqlnode
DB_USER=docker
DB_PASS=docker

5. Adiciona .env no .gitignore
6. Cria .env.example

Configuração de deploy

1. Sobe app no Github
2. Realiza clone
3. Cria .env com credenciais do banco e production
4. Executa yarn sequelize db:migrate
5. Executa app e testa no Insomnia
6. yarn global add pm2
7. export PATH="$(yarn global bin):$PATH" no .bashrc
8. source ~/.bashrc
9. pm2 start src/server.js --name myapp-server
10. pm2 startup ubuntu -u deploy
11. Executa comando retornado
12. pm2 save
13. sudo reboot

Configuração do NGINx/domínio/SSL

1. apt install nginx (como root)
2. cp /etc/nginx/sites-available/default /etc/nginx/sites-available/myapp-server

server {
  server_name nodedeploy.rocketseat.com.br;

  location / {
    proxy_pass http://127.0.0.1:4000;
    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;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_cache_bypass $http_upgrade;
  }
}

4. ln -s /etc/nginx/sites-available/myapp-server /etc/nginx/sites-enabled/
5. nginx -t e service nginx restart
6. Configura DNS e aguarda propagação
7. Acompanha em https://www.whatsmydns.net/
8. Executa certbot (https://certbot.eff.org/lets-encrypt/ubuntubionic-nginx)
