Error while obtaining Keycloak instance

Securing applications
1

Using it in Spring Boot environment the code as follows is generating the following error:

	final Keycloak keycloak = KeycloakBuilder.builder()
			.serverUrl(env.getProperty("keycloak.auth-server-url"))
			.grantType(OAuth2Constants.CLIENT_CREDENTIALS)
			.realm(env.getProperty("keycloak.realm"))
			.clientId(env.getProperty("keycloak.resource"))
			.clientSecret(env.getProperty("keycloak.credentials.secret"))
			
			.build();

I have checked propably any possible configuration parameters combinations, and in any case it does’t work. Please help

Your client setup code looks right. Have you tried running that code standalone instead of inside a Spring Boot environment? There appear to be some problems running inside containers and other environments. E.g.:

Thank you for your answer, it helped, I have figured out what was wrong. It was all about wrong configuration, specifically thet client shoul belog to the master realm. Seems easy :wink:
