Can not fetch values from remote spring config from spring boot client in Kubernetes

问题

Here's my bootstrap.yml of my client

spring:
  cloud:
    config:
      enabled: true
      uri: http://localhost:8888
      label: master

spring.application:
    name: microservices-client

spring.profiles:
    active: dev

Here's my spring config server bootstrap.yml

spring:
  application:
    name: microservices-client

  profiles:
    active: dev

  cloud:
    config:
      uri: http://localhost:8888

And here's my spring config application.yml

server:
  port: 8888

spring:
  cloud:
    config:
      server:
        git:
          uri: ssh://git@riscm.company.com/sem/some_repo.git
          ignoreLocalSshSettings: true
          privateKey:        |

endpoints:
  health:
    sensitive: true

management:

  health:
    solr:
      enabled: false

When I run the config server locally I can pull values from spring boot client, but not when the server runs remotely as a docker image on Kubernetes.

I found one problem in client bootstrap.yml the label should be master and not Master! I went ahead and deployed the microservices to Kubernetes and now I'm getting this error from the log client on Kubernetes. I'm not getting this error when I login directly into the client container.

Please add bellow configuration to bootstrap.xml. I can fixed this issue by putting below configuration.
