I have a problem about creating user through Keycloak in my Spring Cloud example which runs on Docker.

When I make a request through this url http://localhost:8600/api/v1/users/signup (from api gateway to user service), I got this issue on the console.

Here is the error shown below.

    2022-08-24 10:45:22.610  INFO 1 --- [nio-9000-exec-1] c.s.u.controller.UserController          : UserController | signUpUser is started

    javax.ws.rs.NotAuthorizedException: HTTP 401 Unauthorized

Here is the keycloak configuration class defined in user service.

    @Configuration
    public class KeycloakConfig {
    
        public final static String serverUrl = "http://keycloak:8080";
        public final static String realm = "master";
        public final static String clientId = "spring-boot-microservice-keycloak";
        public final static String clientSecret = "ZDyqUYwec1qUeTdxiM2Ym99KiPE73vzU";
        final static String userName = "admin";
        final static String password = "admin";
    
        @Bean
        public KeycloakConfigResolver keycloakConfigResolver(){
            return new KeycloakSpringBootConfigResolver();
        }
    
        @Bean
        public Keycloak keycloak(){
              return Keycloak.getInstance(serverUrl,
                    realm,
                    userName,
                    password,
                    clientId,
                    clientSecret);
        }
    }

Here is the keycloak part of docker-compose.yml

    keycloak:
        image: quay.io/keycloak/keycloak:18.0.2
        environment:
          - KEYCLOAK_ADMIN=admin
          - KEYCLOAK_ADMIN_PASSWORD=admin
        ports:
          - "8181:8080"
        networks:
          - backend
        command:
          - start-dev

Hi, The problem with your code is that you forgot to put the grant-type: "password" when you are creating the instance of keycloak. like that it should work
