k8s 中部署skywalking，并使用kafka传输agent数据

核心配置文件 oap-configMap

创建文件 OAP-ConfigMap.yml

apiVersion: v1
kind: ConfigMap
metadata:
  name: skywalking-oap-cm
data:
  # 存储器类型
  STORAGE: 'elasticsearch7'
  # 存储器地址
  STORAGE_ES_CLUSTER_NODES: 'elasticsearch-client-service.ns-elasticsearch:9200'
  # grpc端口
  CORE_GRPC_PORT: '11800'
  # ui 界面端口
  CORE_REST_PORT: '12800'
  # 使用kafka传输数据
  KAFKA_FETCHER: 'default'
  # kafka地址和端口
  KAFKA_FETCHER_SERVERS: '10.81.58.14:9093'
  # 分片 1
  KAFKA_FETCHER_PARTITIONS_FACTOR: "1"
