How can I receive environment params from docker-compose.yml on java?

Question

I'm doing a Java application with Spring Boot and will receive a cron scheduler from docker-compose.yml. In NetBeans, I can read the values from application.yml, but when I deploy the image on docker server, I can't receive this params.

docker-compose.yml

  integracao-spot:
    container_name: integracao-spot
    image: yuricolen13/integracaospot
    restart: always
    environment:
      jobs_produto_cron: '0 40 9 * * *'
      jobs_estoque_cron: '0 42 9 * * *'
      jobs_vendas_cron: '0 44 9 * * *'

application.yml

jobs:
  produto:
    cron: '0 33 16 * * *'
  estoque:
    cron: '0 34 16 * * *'
  vendas:
    cron: '0 35 16 * * *'

EstoqueJob.class

@Component
@EnableScheduling
public class EstoqueJob {

    public String diretorioLocal = "";
    public String diretorioBucket = "cliente/indiana/indiana/diario/";
    public String lojas = "(5,7,11,50,85)";

    @Scheduled(cron = "${jobs.estoque.cron:-}")
    public void estoqueJob() throws SQLException, IOException {
        
      System.out.println("JOB SCHEDULED");

}

Read params from docker-compose.yml

Answer 1

Try with the following application.yml

jobs:
  produto:
    cron: ${jobs_produto_cron}
  estoque:
    cron: ${jobs_estoque_cron}
  vendas:
    cron: ${jobs_vendas_cron}

Keep in mind according to best practices for naming conventions, environmental variables have to be named with upercase letters. ex JOBS_PRODUTO_CRON

Also in your docker-compose.yml you have to provide the values as list with - .

 ...
 environment:
      - jobs_produto_cron: '0 40 9 * * *'
      - jobs_estoque_cron: '0 42 9 * * *'
      - jobs_vendas_cron: '0 44 9 * * *'
