2 months ago | ⏱️ Estimated effort to review [1-5] | 3, because the PR introduces a comprehensive Helm chart for deploying a Kubernetes application, which involves multiple Kubernetes resources and configurations. The complexity and size of the PR require a detailed review to ensure that all configurations are correct and secure, especially given the inclusion of sensitive data handling and network configurations. |
| 🧪 Relevant tests | No |
| 🔍 Possible issues | Possible Security Concern: The PR includes hard-coded sensitive information in the values.yaml file under the `postgres` section, which includes default passwords. This could lead to security vulnerabilities if not properly managed in production environments. |
| Configuration Concern: The ingress configuration in values.yaml is set to `enabled: false` by default, which might be overlooked and lead to accessibility issues if not configured during deployment. | |
| 🔒 Security concerns | - Sensitive Information Exposure: The default values for PostgreSQL credentials are set in the values.yaml, which could be exposed if not overridden in production. It is crucial to ensure these values are securely managed and overridden in production environments. |
| relevant file | explorer/k8s/helm/general-squid/values.yaml |
| suggestion | Consider removing or securing the default credentials for PostgreSQL to prevent potential security risks. Use Kubernetes secrets or external secret management tools to inject these values at runtime. [important] |
| relevant line | postgresPassword: postgres |
| relevant file | explorer/k8s/helm/general-squid/values.yaml |
| suggestion | Set the default value of `ingress.enabled` to `true` or provide clear documentation to ensure it is configured during deployment to avoid accessibility issues. [medium] |
| relevant line | enabled: false |
| relevant file | explorer/k8s/helm/general-squid/templates/secrets.yaml |
| suggestion | Ensure that secrets are not logged or exposed in any logs or error messages. Consider implementing additional logging filters or masking techniques. [important] |
| relevant line | kind: Secret |
| relevant file | explorer/k8s/helm/general-squid/templates/NOTES.txt |
| suggestion | Add error handling or checks in the NOTES.txt output commands to ensure that the commands only run successfully when the resources are correctly deployed and available. This can prevent misleading outputs if the deployment has issues. [medium] |
| relevant line | 1. Get the application URL by running these commands: |

| Maintainability |
Improve variable naming for clarity.___ **Consider using a more descriptive variable name instead of$name in the general-squid.fullname template to improve readability and maintainability.**

```diff
-{{- $name := default .Chart.Name .Values.nameOverride }}
+{{- $chartName := default .Chart.Name .Values.nameOverride }}

Ensure consistent formatting in the ConfigMap.___ **Use consistent spacing around colons in the `data` section for better readability.** [explorer/k8s/helm/general-squid/templates/configmap.yaml [11]](https://github.com/subspace/infra/pull/306/files#diff-d66ed76d8b61262dac9f882113d622bc8757cc1601d6fe54f2e3d5c668f676f9R11-R11) ```diff -POSTGRES_HOST : {{ .Values.postgres.postgresHost }} +POSTGRES_HOST: {{ .Values.postgres.postgresHost }} ``` | |

Add error handling for autoscaling configuration values.___ **Add error handling for cases where.Values.autoscaling.targetCPUUtilizationPercentage and .Values.autoscaling.targetMemoryUtilizationPercentage might not be set to avoid runtime errors.** [explorer/k8s/helm/general-squid/templates/hpa.yaml [20]](https://github.com/subspace/infra/pull/306/files#diff-fb6365c93b4c77cb14b9c6812ea5e9bf65871c5c2c05e5eebb2c703e08ff4f30R20-R20) ```diff -targetAverageUtilization: {{ .Values.autoscaling.targetCPUUtilizationPercentage }} +targetAverageUtilization: {{ required "A valid .Values.autoscaling.targetCPUUtilizationPercentage is required!" .Values.autoscaling.targetCPUUtilizationPercentage }} ``` | |
Parameterize the PostgreSQL container port for better flexibility.___ **It is recommended to parameterize thepostgres container port to maintain consistency and flexibility, allowing easy updates or configurations changes through values.yaml.** [explorer/k8s/helm/general-squid/templates/statefulset.yaml [30]](https://github.com/subspace/infra/pull/306/files#diff-34a4beeb7cff9593f15b3c367b5e0978fc2d37d452de3dae60d42d2e4b450227R30-R30) ```diff -containerPort: 5432 +containerPort: {{ .Values.postgres.postgresPort }} ``` | |
| Best practice |
Use specific image tags instead of "latest" to ensure deployment consistency.___ **Consider using a more specific tag than "latest" for the images to ensure consistentdeployments and avoid potential issues with unexpected changes when the "latest" image is updated. Using a specific version tag can help maintain stability and predictability in deployments.** [explorer/k8s/helm/general-squid/templates/statefulset.yaml [93-143]](https://github.com/subspace/infra/pull/306/files#diff-34a4beeb7cff9593f15b3c367b5e0978fc2d37d452de3dae60d42d2e4b450227R93-R143) ```diff -image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}" -image: "{{ .Values.image_api.repository }}:{{ .Values.image_api.tag | default .Chart.AppVersion }}" +image: "{{ .Values.image.repository }}:1.2.3" # Replace '1.2.3' with the specific version you want to use +image: "{{ .Values.image_api.repository }}:1.2.3" # Replace '1.2.3' with the specific version you want to use ``` |
Add labels to Role and RoleBinding resources for better resource management.___ **For theRole and RoleBinding resources, consider adding labels for better manageability and to align with best practices. Labels can help in identifying and organizing resources, especially in larger systems.** [explorer/k8s/helm/general-squid/templates/roles.yaml [3-5]](https://github.com/subspace/infra/pull/306/files#diff-68cd8036538538d98d7f0167b97265238f0d6ebaa59bfff1768243854872c5a6R3-R5) ```diff metadata: name: pod-reader-role namespace: {{ .Values.namespace | quote }} + labels: + app: general-squid + role: pod-reader ``` | |
| Security |
Use secure secret management practices instead of encoding secrets in the template.___ **It's a security best practice to avoid using base64 encoding for secrets directly intemplates as it can be easily decoded. Instead, consider using Kubernetes secrets management practices that involve creating secrets outside of the deployment pipeline and referencing them in your deployments.** [explorer/k8s/helm/general-squid/templates/secrets.yaml [7-9]](https://github.com/subspace/infra/pull/306/files#diff-2263555d9c90e7fbb30c288c104841df7b46ca9191265a373035493b90d44681R7-R9) ```diff +# Assume secrets are created separately and securely data: - POSTGRES_PASSWORD: {{ .Values.postgres.postgresPassword | b64enc}} - POSTGRES_USER: {{ .Values.postgres.postgresUser | b64enc}} + POSTGRES_PASSWORD: {{ .Values.postgres.secretNameForPassword }} + POSTGRES_USER: {{ .Values.postgres.secretNameForUser }} ``` |
| Possible issue |
Ensure selector labels match the pod template labels exactly to avoid service disruptions.___ **To avoid potential selector mismatches that can lead to service disruptions, ensure thatthe selector labels match exactly with the labels specified in the pod template of the deployment or stateful set.** [explorer/k8s/helm/general-squid/templates/service.yaml [13-15]](https://github.com/subspace/infra/pull/306/files#diff-cf1635b1b2864123ef8c127a49fd6e83011bab1e368bc6aa8c47d6190b43ce95R13-R15) ```diff selector: - name: {{ include "general-squid.fullname" . }}-app app: {{ include "general-squid.fullname" . }}-app ``` |
