17327-17375: The Deployment configuration looks good with one suggestion.The greptimedb-operator Deployment configuration looks good overall:
- Leader election is enabled which is a good practice.
- Liveness and readiness probes are set up.
- Resource requests and limits are defined.
- The greptimedb-operator ServiceAccount is used.
One suggestion would be to use a specific tag for the operator image instead of
latest. Using a specific version tag makes the deployment more deterministic and reproducible.image: greptime/greptimedb-operator:v1.0.0

21-26: LGTM! The logging configuration provides valuable customization options.The introduced
loggingsection underspecoffers a structured way to configure the application's logging behavior. The chosen default values are sensible and align with common logging practices:
format: textis a widely used log format that balances readability and parsability.level: infostrikes a good balance between verbosity and performance for default logging.logsDir: /data/greptimedb/logsfollows a clear and standard naming convention for log storage.onlyLogToStdout: falseensures logs are written to files for persistence, in addition to stdout.persistentWithData: falseseparates log persistence from application data persistence, providing flexibility.These configuration options enhance the logging capabilities of the application while allowing for further customization if needed. The changes are consistent with the PR objective of introducing a comprehensive logging system.
apis/v1alpha1/testdata/greptimedbcluster/test00/expect.yaml (3)
22-27: LGTM!The logging configuration for the
frontendcomponent looks good. It provides a balanced setup with readable text format, reasonable info level, standard logs directory, and separation of logs from data persistence.
39-44: Looks good!The logging configuration for the
metacomponent is identical to thefrontendcomponent's configuration, which has already been reviewed and approved. Maintaining consistent logging configurations across components is a good practice for maintainability and uniformity.
59-64: Great job maintaining consistency!The logging configuration for the
datanodecomponent is identical to the configurations for thefrontendandmetacomponents, which have already been reviewed and approved. Keeping the logging configurations consistent across all components is excellent for maintainability, uniformity, and ease of understanding.pkg/dbconfig/frontend_config.go (2)
25-27: LGTM!The addition of the
LoggingConfigfield to theFrontendConfigstruct, along with thetomlmapping:",inline"annotation, is a good way to integrate logging configuration into the frontend settings. This change aligns with the PR objective and the provided summary.
40-41: Verify theConfigureLoggingmethod.The addition of the
c.ConfigureLogging(cluster.GetFrontend().GetLogging())call in theConfigureByClustermethod is a good way to ensure that the frontend's logging configuration is set up during the cluster configuration process. This change aligns with the PR objective and the provided summary.However, please ensure that the
ConfigureLoggingmethod handles the logging configuration correctly to avoid any potential issues.Run the following script to verify the
ConfigureLoggingmethod:Verification successful
Logging configuration is correctly implemented and used.
The
ConfigureLoggingmethod is properly implemented in theLoggingConfigstruct (pkg/dbconfig/common.go) and is consistently used across different components, including the Frontend. TheGetLogging()method is correctly defined in the API types, and the logging configuration is appropriately utilized throughout the codebase.Key observations:
- The
ConfigureLoggingmethod is likely inherited or composed intoFrontendConfigfromLoggingConfig.- Consistent usage of
GetLogging()andConfigureLoggingacross Frontend, Meta, Datanode, Flownode, and Standalone components.- Proper handling of logging configuration in various deployer files.
The implementation aligns with the changes made in the PR and appears to be correct and well-structured.

33-35: LGTM!The addition of the
LoggingConfigfield to theStandaloneConfigstruct is consistent with the PR objective to introduce a logging configuration system. Thetomlmapping:",inline"tag is used correctly to ensure the field is serialized inline in the TOML mapping.
73-74: Verify theConfigureLoggingmethod implementation.The change to call the
ConfigureLoggingmethod with the logging configuration obtained from thestandaloneparameter is correct and aligns with the PR objective to integrate logging configuration into the standalone configuration process.Please ensure that the
ConfigureLoggingmethod handles the logging configuration correctly. You can use the following script to search for the method implementation and review its logic:Verification successful
Verified: ConfigureLogging method is correctly implemented and used
The
ConfigureLoggingmethod is implemented for theLoggingConfigstruct, which is embedded in theStandaloneConfigstruct. This design allows theStandaloneConfigto inherit theConfigureLoggingmethod through Go's method promotion feature.The usage in the reviewed code
c.ConfigureLogging(standalone.GetLogging())is correct because:
StandaloneConfigembedsLoggingConfig, inheriting its methods.- The
ConfigureLoggingmethod is available onStandaloneConfiginstances.- The
ConfigureByStandalonemethod inStandaloneConfigis where this configuration is being set up.This implementation ensures that logging configuration is properly handled for standalone instances.

ConfigureLogging method verified, but note the structural difference
The
ConfigureLoggingmethod is correctly implemented and used, but it's important to note that it's not a method ofDatanodeConfigas initially assumed. Instead, it's defined for theLoggingConfigstruct inpkg/dbconfig/common.go:func (c *LoggingConfig) ConfigureLogging(spec *v1alpha1.LoggingSpec) {This method is used consistently across various components, including the datanode:
// in pkg/dbconfig/datanode_config.go c.ConfigureLogging(cluster.GetDatanode().GetLogging())This structure suggests that
DatanodeConfiglikely embeds or has a field of typeLoggingConfig, allowing it to call theConfigureLoggingmethod. This approach promotes code reuse for logging configuration across different components.The implementation and usage are correct, ensuring proper integration of logging settings into the datanode configuration.

52-53: LGTM!The constant is named appropriately and follows the naming convention. The value is constructed correctly by appending "/logs" to the
DefaultDataHomeconstant.pkg/dbconfig/dbconfig_test.go (1)
76-78: LGTM!The changes to the
TestFromClusterForDatanodeConfigWithExtraConfigfunction look good:
- The
extraConfigvariable is updated to include a new[extra]section for testing extra configuration.- The
DatanodeSpecnow includes aLoggingspecification to allow configuring logging settings for the datanode component.- The expected
testConfigstring is updated to match the new[extra]and[logging]sections in the generated configuration.The test case ensures that the
FromClusterfunction correctly generates the datanode configuration with the extra configuration and logging settings.Also applies to: 97-101, 108-115
controllers/greptimedbcluster/deployers/common.go (1)
110-123: LGTM!The
AddLogsVolumefunction is a great addition to theCommonBuilder. It provides a clean and convenient way to configure log sharing between containers in a Pod. The implementation is straightforward and follows the idiomatic Go style.Some key observations:
- The function creates a shared volume named "logs" using
EmptyDirvolume type, which is suitable for ephemeral log storage.- It mounts the volume to the main container at the specified mount path, enabling log sharing.
- The function name and code comments clearly describe the purpose and functionality, making it easy to understand and use.
Overall, this change enhances the functionality of the
CommonBuilderwithout introducing any breaking changes or compatibility issues. Great work!pkg/dbconfig/common.go (2)
145-154: LGTM!The
LoggingConfigstruct provides a clear and structured way to manage logging configuration. The use of pointers for the fields allows distinguishing between unset values and empty strings. Thetomlmappingtags enable easy mapping between the struct fields and configuration keys.
157-170: LGTM!The
ConfigureLoggingmethod provides a clean way to configure theLoggingConfigbased on an externalLoggingSpec. It handles various cases correctly:
- Returns early if
LoggingSpecisnil, preventing unintended changes.- Respects the
IsOnlyLogToStdoutflag by settingDirtonil, ensuring logs are not written to files in this case.- Uses
LogsDirfromLoggingSpecto set theDirfield, allowing customization of the log directory.- Sets
LevelandLogFormatfields based on the corresponding fields inLoggingSpec, ensuring consistency.The method implementation looks good!

controllers/greptimedbcluster/deployers/frontend.go (1)
276-278: LGTM! The conditional log volume addition is a valuable enhancement.The added code segment intelligently checks if the frontend has a logging configuration that is not limited to stdout. If so, it leverages the
AddLogsVolumemethod to mount a volume for persisting logs at the specified directory.This change offers several benefits:
- Enables log retention and analysis beyond the pod's lifecycle.
- Provides flexibility for users to specify a custom logs directory.
- Ensures that the volume is added only when necessary, based on the logging configuration.
Great work on implementing this conditional log volume addition!
controllers/greptimedbcluster/deployers/meta.go (1)
328-330: LGTM!The conditional block correctly adds a logs volume to the pod template spec based on the cluster's logging configuration. It ensures that the volume is mounted only when necessary, i.e., when logging is not set to stdout only. This allows for flexible log handling and facilitates log aggregation and analysis.
controllers/greptimedbcluster/deployers/flownode.go (1)
256-258: LGTM!The conditional block correctly adds a logs volume to the pod template specification when the logging configuration for the flownode is present and not set to only log to stdout. This allows the flownode to write logs to a persistent volume, enabling log aggregation and analysis.

GetLoggingmethod is correctly implemented for theFlownodeSpecstruct, safely returning theLoggingconfiguration or nil based on the instance check.controllers/greptimedbstandalone/deployer.go (1)
460-473: LGTM!The new conditional block correctly adds an
EmptyDirvolume and corresponding mount to the pod template when the specified logging conditions are met. This enables the application to store logs in a pod-level temporary directory, which is automatically cleaned up when the pod is terminated. The changes align with the ephemeral nature of pod-level logging and provide a suitable mechanism for persisting logs within the pod's lifecycle when logging is configured appropriately.controllers/greptimedbcluster/deployers/datanode.go (1)
470-473: LGTM!The conditional block correctly checks for the specific logging configuration scenario and adds the logs volume to the pod template specification when the conditions are met. This change aligns with the PR objective of introducing a comprehensive logging configuration system.

examples/cluster/configure-logging/cluster.yaml (1)
6-10: Logging configuration looks good, but consider the following recommendations:
The debug log level may generate a large volume of logs and impact performance in production environments. Consider using a less verbose log level, such as info or warn, in production.
Ensure that the
/data/greptimedb/logsdirectory exists and has the proper permissions for the GreptimeDB process to write logs.examples/README.md (1)
18-18: LGTM!The new entry for configuring logging in a GreptimeDB cluster is a valuable addition to the examples section. It follows the existing format and structure, and the description accurately summarizes the purpose of the linked example.
