tools/kubeblocks_helm/pika-master-slave-cluster/templates/serviceaccount.yaml (1)
1-7: LGTM!The ServiceAccount resource is correctly defined with the necessary fields. The use of Helm template functions for generating the name, namespace, and labels is a good practice that enhances the deployment's configurability and maintainability.
tools/kubeblocks_helm/pika-master-slave/templates/script.yaml (1)
1-10: LGTM!The ConfigMap resource is well-structured and follows best practices. It effectively manages the
admin.shscript for the Pika master-slave setup.Key points:
- The metadata section correctly sets the name, namespace, and labels for the ConfigMap.
- The data section retrieves the script content from the specified file path.
- The script content is properly indented for YAML formatting.
Regarding the yamllint error on line 7, it is a false positive. The syntax
{{- include "pika.labels" . | nindent 4 }}is valid in Helm templates and does not require any changes.Tools

tools/kubeblocks_helm/pika-master-slave-cluster/templates/role.yaml (1)
1-14: LGTM!The Kubernetes Role is correctly defined with the following observations:
- The
apiVersionandkindfields are accurately specified for a Role resource.- The
metadatasection correctly sets the Role name and namespace using template functions, which allows for dynamic naming based on the cluster.- The
rulessection appropriately grants thecreateverb on theeventsresource in the core API group, enabling the application to create Kubernetes events for logging and monitoring purposes.- The labels are set using a template function, which is a good practice for maintaining consistency across resources.
The permissions are properly scoped to a specific namespace and resource, ensuring the principle of least privilege.
tools/kubeblocks_helm/pika-master-slave/values.yaml (4)
1-2: LGTM!The Pika version is specified correctly.
3-12: LGTM!The Docker image specifications for Pika and Redis are correct:
- The registry is set to docker.io.
- The repository is set to pikadb/pika for Pika and redis for Redis.
- The tag matches the Pika version specified in the
pikasection.- The pull policy is set to IfNotPresent.
13-17: LGTM!The
roleProbeconfiguration for Pika looks good:
- The
failureThresholdis set to 2, which is a reasonable value for marking the container as unhealthy after consecutive failures.- The
periodSecondsis set to 1, ensuring frequent health checks.- The
timeoutSecondsis set to 1, providing a reasonable timeout for the health check response.
18-20: LGTM!The configuration variables are set correctly:
- The
nameOverrideandfullnameOverrideare empty strings, allowing the default naming conventions to be used.- The
clusterDomainis set to ".cluster.local", which is a common default value for Kubernetes clusters.tools/kubeblocks_helm/pika-master-slave-cluster/templates/rolebinding.yaml (1)
1-15: LGTM! The RoleBinding is properly configured.The
rolebinding.yamlfile correctly defines a Kubernetes RoleBinding resource that associates a specific Role with a ServiceAccount within the designated namespace. The use of Helm template functions for dynamic generation of the RoleBinding name, labels, and other values ensures consistency and ease of management across different deployments.Properly configured RoleBindings are essential for enforcing security and access control policies within the Kubernetes cluster. They ensure that ServiceAccounts have the necessary permissions to perform their intended functions while adhering to the principle of least privilege.
It's crucial to regularly review and audit RoleBindings to maintain a secure and well-managed Kubernetes environment. Incorrect or overly permissive RoleBindings can lead to security vulnerabilities and unauthorized access to cluster resources.
Great job on properly structuring and configuring this RoleBinding!

The ClusterDefinition resource is well-structured and aligns with the PR objectives.
The resource follows the Kubernetes CRD conventions and defines a master-slave topology for the Pika cluster, enabling the desired operational capabilities within a Kubernetes environment.
The use of the include template function for generating labels is a good practice and allows for consistent labeling across resources.
The default: true flag simplifies deployment for users who may not need to specify alternative configurations.
However, there is a syntax error on line 6 that needs to be addressed. The {{- syntax is incorrect. To fix the issue, remove the - character:

Correct indentation in the volumeClaimTemplates section
The volumeClaimTemplates section at lines 31-43 may have incorrect indentation, which could cause YAML parsing errors. The Helm template directives and YAML keys need proper alignment.
Apply the following diff to correct the indentation:
{{- if $.Values.persistence.enabled }}
- volumeClaimTemplates:
+ volumeClaimTemplates:
{{- with $.Values.persistence.pikaData }}
- - name: data # ref componentDefinition.containers.volumeMounts.name
+ - name: data # ref componentDefinition.containers.volumeMounts.name

{{- end }}
{{- end }}Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

2-7: LGTM: Metadata section looks goodThe
kind,metadata.name,metadata.namespace, andmetadata.labelsare correctly defined using Helm templating.
16-30: LGTM: ComponentSpecs section is well-definedThe componentSpecs section is well-structured and includes all necessary configurations for the Pika component, including name, component definition reference, enabled logs, service account, and resource specifications.
31-43: LGTM: VolumeClaimTemplates section is correctly definedThe volumeClaimTemplates section is well-structured and correctly conditional based on the persistence.enabled flag. It properly defines the persistent volume claim for Pika data, including storage class, access mode, and resource requests.
1-43: Overall, the Cluster CRD is well-defined with minor improvements neededThis file successfully defines a Kubernetes Custom Resource for a Pika master-slave cluster using Helm templating. It includes all necessary sections such as metadata, spec, componentSpecs, and volumeClaimTemplates.
A few minor improvements have been suggested:
- Updating the API version to the latest stable or beta version.
- Fixing indentation issues in the affinity and tolerations sections.
- Improving the replicas calculation for better default handling.
Once these changes are implemented, the file will be in excellent shape for managing Pika master-slave clusters in a Kubernetes environment using KubeBlocks.

🛠️ Refactor suggestion
Consider updating the API version
The current API version apps.kubeblocks.io/v1alpha1 might be outdated. As suggested in a previous review, there may be a beta version available.
Consider updating the API version to the latest stable or beta version if available. For example:
apiVersion: apps.kubeblocks.io/v1beta1Please verify the latest supported version in the KubeBlocks documentation.

🛠️ Refactor suggestion
Improve replicas calculation for better default handling
The current replicas calculation might not work as intended when $.Values.slaveCount is undefined.
Consider updating the replicas calculation to handle the default case more explicitly:
replicas: {{ add (int (default 1 $.Values.slaveCount)) 1 }}This change ensures that when slaveCount is not set, it defaults to 1, resulting in 2 replicas (1 master + 1 slave).

🛠️ Refactor suggestion
Use hostnames instead of IPs for slaveof configuration
In Kubernetes environments, IP addresses are ephemeral resources. Using hostnames instead of IPs ensures better reliability and stability.
Modify the slaveof command to use hostnames instead of IPs. Replace lines 47-48 with:
echo "exec:redis-cli -h ${pod_name}${headless} -p 9221 slaveof ${pod0_svc} 9221"
redis-cli -h "${pod_name}${headless}" -p 9221 slaveof "${pod0_svc}" 9221This change ensures that the slaveof command uses the stable headless service hostname instead of potentially changing IP addresses.
Add error handling for redis-cli command execution
To ensure reliability, it's important to check if the redis-cli command executed successfully and handle any errors appropriately.
Apply this diff to add error handling:
47 echo "exec:redis-cli -h ${pod_name}${headless} -p 9221 slaveof ${pod0_svc}:9221"
48 redis-cli -h "${pod_name}${headless}" -p 9221 slaveof "${pod0_svc}" 9221
