bom dia pessoal! criei uma maquina virtual na amazonAWS e estou tentando configurar meu projeto spring boot com uma base de dados postgress por lá, estou acessando a maquina linux, ja clonei meu projeto springboot lá e criei uma base dados dentro da amazon, ja consigo inclusive acessar essa base de dados aqui da minha maquina local, e o meu projeto tambem roda com perfeição aqui na minha maquina, mas ao rodar o comando java -jar biblioteca-api-0.0.1-SNAPSHOT.jar obtenho o erro abaixo

vejam que consigo acessar minha base de dados na amazon sem problema

Solucao aceita

Jonathan_Medeiros 17 de dez. de 2022

Pela documentação, você teria que configurar os security groups com as permissões de acesso e associar sua ec2 com o rds através da mesma vpc para que seja possível haver comunicação entre ambos recursos.

Veja: Connecting an EC2 instance and an RDS database automatically - Amazon Relational Database Service
