122-124: New debug configuration parameters added.The addition of
debug.enabled,debug.image, anddebug.resourcesenhances the chart's functionality by allowing users to configure a debug pod. It would be beneficial to include examples or further documentation on how to use these parameters effectively.

1-2: Ensure Helm conditional syntax is correct.The Helm conditional syntax used here is correct and follows best practices for conditional rendering in Helm templates. This allows the debug deployment to be enabled or disabled via the
.Values.debug.enabledflag.Tools

[error] 1-1: syntax error: expected the node content, but found '-'

3-4: Correct API version and resource kind.The
apiVersionandkindfields are correctly set for a Kubernetes deployment. This ensures that the Kubernetes cluster interprets the resource as a deployment.
6-10: Metadata and spec configuration.The metadata configuration, including the deployment name and namespace, is dynamically set using Helm values, which is a good practice for ensuring deployments are correctly named and placed within the intended namespace.
11-14: Replica and selector configuration.Setting
replicas: 1is appropriate for a debug deployment to ensure only one instance is running. The label selector is correctly configured to match the deployment's labels, ensuring that the right pods are managed under this deployment.
16-18: Template metadata labels.The labels within the pod template are consistent with the deployment's labels, which is crucial for correct pod selection and management.
20-25: Container configuration and resource limits.The container image is dynamically configured using Helm values, which is flexible and allows for easy updates. The conditional inclusion of resource limits (
resources) based on.Values.debug.resourcesis a best practice to ensure that the deployment can be configured to meet different resource requirements.
26-27: Ensure proper closure of Helm conditionals.The Helm conditionals are properly closed, which is essential to avoid rendering issues when the Helm chart is processed.

470-487: Approve the addition of the debug section and suggest verification.The new
debugsection is a valuable addition for enhancing observability and troubleshooting. Please ensure the specified imagedocker.io/greptime/greptime-tool:20240905-67eaa147is available and that the resource allocations are appropriate for the debug pod's expected usage.Run the following script to verify the image availability:
17-17: Verify the new image tag for compatibility and availability.The image tag for the initializer has been updated to
v0.1.0-alpha.29. It's crucial to ensure that this tag exists in the registry and is compatible with the system's requirements.Run the following script to verify the image tag:
Verification successful
Image tag
v0.1.0-alpha.29is available in the Docker registry.The image tag
v0.1.0-alpha.29for the initializer is confirmed to be available. Ensure that this version is compatible with your system's requirements. If compatibility checks are needed, consider performing them manually.Scripts executed

5-5: Version badge updated correctly.The version badge has been updated to
0.2.10, reflecting the new release of the Helm chart.
180-180: Initializer image tag updated correctly.The
initializer.taghas been updated tov0.1.0-alpha.29, reflecting the new version of the initializer image.

1-4: Correct use of Helm conditionals and deployment setup.The Helm conditionals are correctly used to enable or disable the debug pod based on configuration values. The
apiVersionandkindare appropriately set for a Kubernetes deployment.Tools

5-9: Well-configured metadata for the debug pod.The metadata block correctly uses Helm templating for the deployment's name and namespace, ensuring flexibility and correct placement in clusters. Labels are consistently applied, which is crucial for managing resources in Kubernetes.
10-25: Well-defined spec for the debug pod.The deployment spec is well-configured with appropriate settings for replicas, selector, and template. The use of dynamic values for the container image ensures flexibility. It's important to ensure that
.Values.debug.resourcesis well-defined in the Helm values to prevent potential resource allocation issues.Please verify that resource limits and requests are defined in the Helm chart values to ensure proper resource management.
26-27: Correct closure of Helm conditionals.The Helm conditionals are correctly closed, ensuring that the debug pod configuration is only included when enabled.
1-1: Clarification on yamllint error.The reported yamllint error is likely a false positive due to the Helm templating syntax used, which yamllint may not fully understand. This does not impact the functionality of the Helm chart.

470-487: Approve the debug pod configuration with a suggestion.The debug pod configuration is well-structured and follows best practices. However, consider the previous suggestion to rename
debugPodtodebugPodsfor better clarity.
