Cannot disable Spring Cloud Config via spring.cloud.config.enabled:false


Let me preface this by saying that I'm not using Spring Cloud Config directly, it is transitive via Spring Cloud Hystrix starter.

When only using @EnableHystrix, Spring Cloud also tries to locate a configuration server, expectedly unsuccessfully, since I'm not using one. The application works just fine, as far as I can tell, but the problem is in the status checks. Health shows DOWN because there is no config server.

Browsing the source of the project, I'd expect spring.cloud.config.enabled=false to disable this functionality chain, however this is not what I'm seeing.

After upgrading to 1.0.0.RC1 (which adds this property) and using @EnableCircuitBreaker:

{
    status: "DOWN",
    discovery: {
        status: "DOWN",
        discoveryClient: {
            status: "DOWN",
            error: "org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.cloud.client.discovery.DiscoveryClient] is defined"
        }
    },
    diskSpace: {
        status: "UP",
        free: 358479622144,
        threshold: 10485760
    },
    hystrix: {
        status: "UP"
    },
    configServer: {
        status: "DOWN",
        error: "org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http: //localhost: 8888/bootstrap/default/master":Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect"
    }
}

After checking the configprops endpoint, it seems that my properties are being overridden. Note that the parent has the configClient enabled.

parent: {
    configClientProperties: {
        prefix: "spring.cloud.config",
        properties: {
            password: null,
            discovery: {
                enabled: false,
                serviceId: "CONFIGSERVER"
            },
            name: "bootstrap",
            label: "master",
            env: "default",
            uri: "http://localhost:8888",
            enabled: true,
            failFast: false,
            username: null
        }
    }
},
configClientProperties: {
    prefix: "spring.cloud.config",
    properties: {
        password: null,
        discovery: {
            enabled: false,
            serviceId: "CONFIGSERVER"
        },
        name: "bootstrap",
        label: "master",
        env: "default",
        uri: "http://localhost:8888",
        enabled: false,
        failFast: false,
        username: null
    }
}

Any direction would be appreciated, if it seems I'm not doing this correctly.


Solution

  • The config server is needed during bootstrap, and that's where the parent property sources come from. It looks like all you need to do is move your spring.cloud.config.enabled property to bootstrap.yml (or .properties).
