使用 kubectl 执行如下命令部署 mindoc 服务 ：

kubectl create -f skywalking-server.yaml --namespace=你的命名空间

kubectl create -f skywalking-server.yaml --namespace=bmp-prod

项目配置 skywalking

            - name: JAVA_TOOL_OPTIONS
              value: >-
                -Xms256M -Xmx512M -XX:MaxMetaspaceSize=192M
                -XX:MetaspaceSize=192M -XX:+PrintGCDetails
                -XX:+PrintGCTimeStamps -XX:GCLogFileSize=20m

                -XX:HeapDumpPath=/logs/heaperror.log -Xloggc:/logs/gcerror.log
                -javaagent:/skywalking/agent/skywalking-agent.jar
                -Dskywalking.agent.service_name=tianyin-edu-bizapi
                -Dskywalking.collector.backend_service=192.168.3.27:30400

核心是在JAVA_TOOL_OPTIONS 变量增加一下内容，其中backend_service 指向 skywalking 的服务接口：

-javaagent:/skywalking/agent/skywalking-agent.jar -Dskywalking.agent.service_name=tianyin-edu-bizapi -Dskywalking.collector.backend_service=192.168.3.27:30400
