Spring Metrics Collector Configuration with Spring cloud data flow docker-compose

Question

I have the following docker-compose.yml I have data flow server running, kafka, zookeeper, mysql, metrics collector.

Configuration: (I provide only the dataflow-server (1.5.2 release), metrics collector) metrics-collector: image: springcloud/metrics-collector-kafka-10 environment: - spring.security.user.name=spring - spring.security.user.password=cloud - spring.cloud.stream.kafka.binder.brokers=kafka:9092 - spring.cloud.stream.kafka.binder.zkNodes=zookeeper:2181 ports: - "8080:8080"

depends_on:
  - kafka

dataflow-server: image: springcloud/spring-cloud-dataflow-server-local:${DATAFLOW_VERSION} container_name: dataflow-server ports: - "9393:9393" environment: - spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.kafka.binder.brokers=kafka:9092 - spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.kafka.binder.zkNodes=zookeeper:2181 - spring_datasource_url=jdbc:mysql://mysql:3306/dataflow - spring_datasource_username=root - spring_datasource_password=rootpw - spring_datasource_driver-class-name=org.mariadb.jdbc.Driver - spring.cloud.dataflow.metrics.collector.uri=http://172.24.173.136:8080 - spring.cloud.dataflow.metrics.collector.username=spring - spring.cloud.dataflow.metrics.collector.password=cloud

However I am getting the following error: dataflow-server | 2018-10-01 23:15:41.370 WARN 1 --- [x-MetricStore-1] o.s.c.d.s.c.support.MetricStore : Failure while requesting metrics from url 'http://172.24.173.136:8080/collector/metrics/streams': '401 '. Unauthorized, please provide valid credentials.

I am following this documentation link : https://github.com/spring-cloud/spring-cloud-dataflow-metrics-collector

What else is missing in the configuration. The only thing that I think is might be for scdf 2.x version then are there equivalent properties in scdf 1.x - spring.security.user.name=spring - spring.security.user.password=cloud

Answer 1

You're using the metrics-collector-kafka-10 Docker image and that's on Spring Boot 1.5.x. In that Boot baseline, the security properties are different.

Please follow the 1.x version of Metrics Collector README for the compatible k/v pairs.

The master branch of the Metrics Collector defaults to Spring Boot 2.x compatibility. If you'd like to use the 2.x version of the Metrics Collector, we have a different Docker image for it, and in that release, you'd supply the creds via spring.security.user.name and spring.security.user.password properties. This change is driven by Spring Boot itself.
