5.2. 自定义 Data Grid 配置

您可以将 Data Grid 配置添加到 XML、YAML 或 JSON 格式的 ConfigMap 中。

缓存模板

XML

<infinispan>
  <cache-container>
    <distributed-cache-configuration name="base-template">
      <expiration lifespan="5000"/>
    </distributed-cache-configuration>
    <distributed-cache-configuration name="extended-template"
                                     configuration="base-template">
      <encoding media-type="application/x-protostream"/>
      <expiration lifespan="10000"
                  max-idle="1000"/>
    </distributed-cache-configuration>
  </cache-container>
</infinispan>

YAML

            maxIdle: "1000"

            }
          }
        }
      }
    }
  }

日志配置

您还可以以 XML 格式包括 Apache Log4j 配置作为 ConfigMap 的一部分。

注意

使用 Infinispan CR 中的 spec.logging.categories 字段来调整 Data Grid 集群的日志级别。只有在需要高级基于文件的日志记录功能时才添加 Apache Log4j 配置。 

apiVersion: v1
kind: ConfigMap
metadata:
   name: logging-config
   namespace: rhdg-namespace
data:
   infinispan-config.xml: >
     <infinispan>
       <!-- Add custom Data Grid configuration if required. -->
       <!-- You can provide either Data Grid configuration, logging configuration, or both. -->
     </infinispan>

   log4j.xml: >
     <?xml version="1.0" encoding="UTF-8"?>
     <Configuration name="ServerConfig" monitorInterval="60" shutdownHook="disable">
         <Appenders>
             <!-- Colored output on the console -->
             <Console name="STDOUT">
                 <PatternLayout pattern="%d{HH:mm:ss,SSS} %-5p (%t) [%c] %m%throwable%n"/>
             </Console>
         </Appenders>

         <Loggers>
             <Root level="INFO">
                 <AppenderRef ref="STDOUT" level="TRACE"/>
             </Root>
             <Logger name="org.infinispan" level="TRACE"/>
         </Loggers>
     </Configuration>
