Chapter 56. EntityUserOperatorSpec schema reference

Used in: EntityOperatorSpec

Full list of EntityUserOperatorSpec schema properties

Configures the User Operator.

56.1. Logging
复制链接

The User Operator has its own preconfigured loggers:

Expand

Logger	Description	Default Level
`rootLogger`	Default logger for all classes	INFO
`jetty`	Logs HTTP server activity	INFO

The User Operator uses the Apache log4j2 logger implementation. Use the logging property to configure loggers and logger levels.

You can set log levels using either the inline or external logging configuration types.

Specify loggers and levels directly in the custom resource for inline configuration:

Example inline logging configuration

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
spec:
  kafka:
    # ...
  entityOperator:
    # ...
    userOperator:
      watchedNamespace: my-topic-namespace
      reconciliationIntervalMs: 60000
      logging:
        type: inline
        loggers:
          rootLogger.level: INFO
          logger.jetty.level: WARN
  # ...

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
spec:
  kafka:
    # ...
  entityOperator:
    # ...
    userOperator:
      watchedNamespace: my-topic-namespace
      reconciliationIntervalMs: 60000
      logging:
        type: inline
        loggers:
          rootLogger.level: INFO
          logger.jetty.level: WARN
  # ...

You can define additional loggers by specifying the full class or package name using logger.<name>.name. For example, to configure more detailed logging for the User Operator inline:

Example custom inline loggers

# ...
logger.uop.name: io.strimzi.operator.user 
logger.uop.level: DEBUG 
logger.abstractcache.name: io.strimzi.operator.user.operator.cache.AbstractCache 
logger.abstractcache.level: TRACE

# ...
logger.uop.name: io.strimzi.operator.user


logger.uop.level: DEBUG


logger.abstractcache.name: io.strimzi.operator.user.operator.cache.AbstractCache


logger.abstractcache.level: TRACE

1: Creates a logger for the user package.
2: Sets the logging level for the user package.
3: Creates a logger for the AbstractCache class.
4: Sets the logging level for the AbstractCache class.

Alternatively, you can reference an external ConfigMap containing a complete log4j2.properties file that defines your own log4j2 configuration, including loggers, appenders, and layout configuration:

Example external logging configuration

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
spec:
  kafka:
    # ...
  entityOperator:
    # ...
    userOperator:
      watchedNamespace: my-topic-namespace
      reconciliationIntervalMs: 60000
      logging:
        type: external
        valueFrom:
          configMapKeyRef:
            # name and key are mandatory
            name: customConfigMap
            key: log4j2.properties
   # ...

apiVersion: kafka.strimzi.io/v1beta2
kind: Kafka
metadata:
  name: my-cluster
spec:
  kafka:
    # ...
  entityOperator:
    # ...
    userOperator:
      watchedNamespace: my-topic-namespace
      reconciliationIntervalMs: 60000
      logging:
        type: external
        valueFrom:
          configMapKeyRef:
            # name and key are mandatory
            name: customConfigMap
            key: log4j2.properties
   # ...

Garbage collector (GC)

Garbage collector logging can also be enabled (or disabled) using the jvmOptions property.

Property	Property type	Description
watchedNamespace	string	The namespace the User Operator should watch.
image	string	The image to use for the User Operator.
reconciliationIntervalSeconds	integer	The `reconciliationIntervalSeconds` property has been deprecated, and should now be configured using `.spec.entityOperator.userOperator.reconciliationIntervalMs`. Interval between periodic reconciliations in seconds. Ignored if reconciliationIntervalMs is set.
reconciliationIntervalMs	integer	Interval between periodic reconciliations in milliseconds.
zookeeperSessionTimeoutSeconds	integer	The `zookeeperSessionTimeoutSeconds` property has been deprecated. This property has been deprecated because ZooKeeper is not used anymore by the User Operator. Timeout for the ZooKeeper session.
secretPrefix	string	The prefix that will be added to the KafkaUser name to be used as the Secret name.
livenessProbe	`Probe`	Pod liveness checking.
readinessProbe	`Probe`	Pod readiness checking.
resources	ResourceRequirements	CPU and memory resources to reserve.
logging	`InlineLogging`, `ExternalLogging`	Logging configuration.
jvmOptions	`JvmOptions`	JVM Options for pods.
