Overview

Bancos de Dados Relacionais (SQL) na AWS com Amazon RDS

Repositório para o Live Coding DIO do dia 24/11/2021

Serviços utilizados

  • Amazon RDS
  • AWS Lambda
  • MySQL Workbench

Criando o banco de dados no Amazon RDS

  • AWS Console -> Amazon RDS -> Create database -> Standard create -> MySQL -> Versão padrão -> Free Tier -> DB instance identifier [dio-live-db] -> Master username [admin] -> Master password [sua_senha_forte] -> DB instance size - padrão -> Storage - configurações padrão -> Connectivity - vpc padrão -> Publicly accessible [yes] -> VPC Security - padrão -> Database authentication [password authentication] -> Create database
  • Selecionar o DB criado -> Connectivity & security -> Copiar endpoint.

No MySQL Workbench

  • MySQL Connections -> New -> Connection name [DioLive] -> Hostname - colar o endpoint copiado no passo anterior -> Username [admin] -> Teste Connection -> Password [sua_senha]

Em caso de problemas na conexão

  • Security -> VPC security groups -> Acessar o SG criado -> Inbound -> Edit -> Add rule -> type [All traffic] -> Source [Anywhere] -> Save

No MySQL Workbench

  • Selecionar a conexão criada -> Password [sua_senha_forte]

Criando queries

  • Criar um database:

    CREATE DATABASE PERMISSIONS_DB;

  • Acessar o db criado

    USE PERMISSIONS_DB;

  • Criar uma tabela de usuários

    CREATE TABLE user (
      id bigint(20) NOT NULL, 
      email varchar(40) NOT NULL,
      username varchar(15) NOT NULL,
      password varchar(100) NOT NULL,
      PRIMARY KEY (id)
    );
    
  • Criar uma tabela de carrinho de compras

    CREATE TABLE role (
      id bigint(20) NOT NULL,
      name varchar(60) NOT NULL, 
      PRIMARY KEY (id)
    );
    
  • Criar uma tabela associativa de itens em um carrinho de compras

    CREATE TABLE ITEMS (
      cart_id INT NOT NULL,
      product_id INT NOT NULL,
      quantity DECIMAL(15,2) NOT NULL,
      FOREIGN KEY (cart_id) REFERENCES CARTS (id),
      FOREIGN KEY (product_id) REFERENCES PRODUCTS (id)
    );
    
  • Descrevendo o esquema de uma tabela

    CREATE TABLE user_roles (
      user_id bigint(20) NOT NULL,
      role_id bigint(20) NOT NULL,
      FOREIGN KEY (user_id) REFERENCES user (id) ON DELETE RESTRICT ON UPDATE CASCADE,
      FOREIGN KEY (role_id) REFERENCES role (id) ON DELETE RESTRICT ON UPDATE CASCADE,
      PRIMARY KEY (user_id, role_id)
    );
    
  • Inserindo dados em tabelas

    INSERT INTO user VALUES (1, '[email protected]', 'Cassiano', 'strongpasswd');
    INSERT INTO user VALUES (2, '[email protected]', 'Joao', 'strongpasswd');
    
    INSERT INTO role VALUES (3, 'ADMIN');
    INSERT INTO role VALUES (4, 'USER');
    
    INSERT INTO user_roles VALUES (1, 3);
    INSERT INTO user_roles VALUES (1, 4);
    INSERT INTO user_roles VALUES (2, 4);
    
  • Selecionando todos os registros de uma tabela

    SELECT * FROM [table_name];
    
  • Selecionando dados da tabela associativa

    SELECT user.id, user.email, user.username, role.id AS role_id, role.name AS role_name
    FROM user 
    JOIN user_roles on (user.id=user_roles.user_id)
    JOIN role on (role.id=user_roles.role_id);
    

Realizando queries no Amazon RDS a partir de uma função no AWS Lambda

Criando a função Lambda

  • Acessar o AWS Lambda console -> Create function -> Author from scratch -> Function name [RDSQuery] -> Runtime - Python3.9 -> Create new role from AWS policy template -> Role name [RDSQueryFromLambdaRole] -> Create function

Configurando permissões de acesso ao RDS

  • Selecionar a função criada -> Configuration -> Permissions -> Selecionar a função criada e abrir no console do AWS IAM
  • Attach policies -> Pesquisar pela policy AWSLambdaVPCAccessExecutionRole -> Attach policy

Desenvolvendo o código da função Lambda

  • Editor de código da função criada -> Inserir o código disponível na pasta src deste projeto

Importando a biblioteca pymysql utilizando Lambda Layers

  • Lambda Dashboard -> Layers -> Create layer -> Name [pymysql_layer] -> Upload a .zip file - o arquivo pyton.zip está disponível na pasta src do projeto -> Compatible architectures x86_64 -> Compatible runtimes - Python 3.9 -> Create
  • Lambda Dashboard -> selecionar a função criada -> Layers -> Add a layer -> Custom layers -> selecionar o layer criado anteriormente -> Add

Testando a função criada

  • Test -> New event -> Template -> Hello World -> Name [test] -> Save changes -> Test
