WalkthroughThe pull request introduces the Tinkerbell ecosystem components, specifically focusing on the Rufio and Smee services. These components are added as Helm charts with comprehensive configurations for deployment, role-based access control (RBAC), and custom resource definitions (CRDs). The changes include adding new release entries in distribution bundles, creating Helm chart configurations for Rufio and Smee, defining CRDs for hardware and BMC management, and setting up deployment templates with flexible configuration options.

🧹 Nitpick comments (17)
packages/system/tinkerbell/charts/rufio/templates/service-account.yaml (1)
1-7: Consider adding standard labels for better resource management.The ServiceAccount template looks good, but consider adding standard Kubernetes labels for better resource management and traceability.
Add common labels using Helm's built-in helper:
apiVersion: v1 kind: ServiceAccount metadata: name: {{ .Values.serviceAccountName }} namespace: {{ .Release.Namespace | quote }} + labels: + {{- include "rufio.labels" . | nindent 4 }}🧰 Tools

packages/system/tinkerbell/charts/rufio/values.schema.json (1)
2-2: Consider upgrading JSON Schema draft version.The schema uses Draft-04 which is quite old (from 2013). Consider upgrading to the latest Draft 2020-12 to leverage modern features and improved validation capabilities.
- "$schema": "http://json-schema.org/draft-04/schema#", + "$schema": "https://json-schema.org/draft/2020-12/schema"packages/system/tinkerbell/charts/smee/templates/service-account.yaml (1)
2-6: Consider adding security annotations and labels.While the basic ServiceAccount configuration is correct, consider enhancing it with:
- Security annotations (e.g.,
kubernetes.io/enforce-mountable-secrets)- Common labels for better resource management
- Explicit automountServiceAccountToken setting
Apply this diff to enhance security and maintainability:
apiVersion: v1 kind: ServiceAccount metadata: name: {{ .Values.name }} namespace: {{ .Release.Namespace | quote }} + labels: + app.kubernetes.io/name: {{ .Values.name }} + app.kubernetes.io/instance: {{ .Release.Name }} + app.kubernetes.io/managed-by: {{ .Release.Service }} + annotations: + kubernetes.io/enforce-mountable-secrets: "true" + automountServiceAccountToken: falsepackages/system/tinkerbell/charts/rufio/templates/_scheduling.tpl (2)
1-4: Consider adding toleration configuration options.The
singleNodeClusterConfigtemplate could benefit from additional flexibility for single-node clusters where running on control-plane nodes might be necessary.Consider adding a conditional block:
{{- define "singleNodeClusterConfig" }} +{{- if not .Values.allowControlPlaneScheduling }} - effect: NoSchedule key: node-role.kubernetes.io/control-plane +{{- end }} {{- end }}
6-12: Consider using Exists operator for more flexible worker node selection.The current
DoesNotExistoperator might be too restrictive. UsingExistswith a node selector could provide more flexibility while maintaining the preference for worker nodes.Consider this alternative approach:
{{- define "preferWorkerNodes" }} - weight: {{ .nodeAffinityWeight }} preference: matchExpressions: - key: node-role.kubernetes.io/control-plane - operator: DoesNotExist + operator: NotIn + values: + - "" {{- end }}packages/system/tinkerbell/charts/smee/templates/_scheduling.tpl (1)
1-12: Consider creating a shared scheduling template library.This file is identical to
rufio/templates/_scheduling.tpl. Consider creating a common template library to avoid duplication and maintain consistency across services.You could:
- Move these templates to a shared location (e.g.,
templates/_shared/scheduling.tpl)- Include them in both charts using Helm's template importing mechanisms
packages/system/tinkerbell/charts/rufio/templates/leader-election-role-binding.yaml (1)
4-7: Add recommended Kubernetes labels.Consider adding standard Kubernetes labels for better resource management and visibility.
Add recommended labels:
metadata: name: {{ .Values.rufioLeaderElectionRoleBindingName }} namespace: {{ .Release.Namespace | quote }} + labels: + app.kubernetes.io/name: {{ .Chart.Name }} + app.kubernetes.io/instance: {{ .Release.Name }} + app.kubernetes.io/version: {{ .Chart.Version }} + app.kubernetes.io/component: leader-electionpackages/system/tinkerbell/charts/rufio/templates/role-binding.yaml (1)
19-19: Standardize service account reference across services.There's an inconsistency in service account reference:
- Smee uses
.Values.name- Rufio uses
.Values.serviceAccountNameConsider standardizing this across all Tinkerbell services.
packages/system/tinkerbell/charts/rufio/Chart.yaml (1)
4-4: Use a more stable icon URL referenceThe icon URL references a specific commit hash which might become invalid if the repository history is modified.
Consider using a tag or main branch reference instead:
-icon: https://github.com/tinkerbell/artwork/blob/6f07de53d75cb8932dbc7d14201e038cf3a3b230/Tinkerbell-Icon-Dark.png +icon: https://github.com/tinkerbell/artwork/raw/main/Tinkerbell-Icon-Dark.pngpackages/system/tinkerbell/charts/rufio/templates/deployment.yaml (1)
54-65: Consider adjusting probe timeouts.The readiness probe's initial delay (5s) might be too short for the application to initialize properly, especially in resource-constrained environments.
readinessProbe: httpGet: path: /readyz port: 8081 - initialDelaySeconds: 5 + initialDelaySeconds: 10 periodSeconds: 10packages/system/tinkerbell/charts/smee/values.yaml (1)
8-9: Consider using digest instead of tag for container images.For better security and reproducibility, consider using image digest instead of tag.
-image: quay.io/tinkerbell/smee:v0.15.1 +image: quay.io/tinkerbell/smee@sha256:<digest>packages/system/tinkerbell/charts/smee/templates/deployment.yaml (1)
76-77: Consider adding validation for tinkWorkerImage.The
requiredfunction is used to enforce the presence of tinkWorkerImage, but consider adding a pattern validation to ensure it's a valid image reference.- value: {{ join " " ( append .Values.http.additionalKernelArgs ( printf "tink_worker_image=%s" ( required "missing tinkWorkerImage" .Values.tinkWorkerImage ) ) ) | quote }} + {{- $tinkWorkerImage := required "missing tinkWorkerImage" .Values.tinkWorkerImage -}} + {{- if not (regexMatch "^[a-z0-9]+(?:[._-][a-z0-9]+)*(?:/[a-z0-9]+(?:[._-][a-z0-9]+)*)*(?::[a-z0-9]+(?:[._-][a-z0-9]+)*)?$" $tinkWorkerImage) -}} + {{- fail (printf "Invalid tinkWorkerImage format: %s" $tinkWorkerImage) -}} + {{- end -}} + value: {{ join " " ( append .Values.http.additionalKernelArgs ( printf "tink_worker_image=%s" $tinkWorkerImage ) ) | quote }}packages/system/tinkerbell/charts/rufio/crds/bmc.tinkerbell.org_machines.yaml (2)
68-71: Consider strengthening the host validation.The current validation only checks for non-empty string. Consider adding pattern validation for IP addresses and hostnames.
host: description: Host is the host IP address or hostname of the Machine. minLength: 1 + pattern: ^(([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9\-]*[a-zA-Z0-9])\.)*([A-Za-z0-9]|[A-Za-z0-9][A-Za-z0-9\-]*[A-Za-z0-9])$|^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$ type: string
283-288: Add examples to the powerState enum description.Consider adding examples and implications of each power state to help users understand the expected behavior.
powerState: description: Power is the current power state of the Machine. + description: | + Power is the current power state of the Machine. + Possible values: + * "on" - Machine is powered on and operational + * "off" - Machine is completely powered off + * "unknown" - Power state could not be determined enum: - "on" - "off" - unknown type: stringpackages/system/tinkerbell/charts/smee/crds/hardware-crd.yaml (2)
110-111: MAC address validation pattern could be more flexible.The current MAC address validation pattern is strict. Consider supporting different MAC address formats.
- pattern: ([0-9a-f]{2}[:]){5}([0-9a-f]{2}) + pattern: ^([0-9A-Fa-f]{2}[:-]){5}([0-9A-Fa-f]{2})$|^([0-9A-Fa-f]{2}){6}$ type: string
123-125: Improve VLAN ID validation description.The validation pattern for VLAN ID could benefit from a more detailed description.
- description: validation pattern for VLANDID is a string number between 0-4096 + description: | + VLAN ID must be a number between 0-4096, where: + - 0: Indicates no VLAN tagging + - 1-4094: Valid VLAN IDs for normal use + - 4095: Reserved for implementation use + Multiple VLAN IDs can be specified using comma separation. pattern: ^(([0-9][0-9]{0,2}|[1-3][0-9][0-9][0-9]|40([0-8][0-9]|9[0-6]))(,[1-9][0-9]{0,2}|[1-3][0-9][0-9][0-9]|40([0-8][0-9]|9[0-6]))*)$ type: stringpackages/system/tinkerbell/charts/rufio/crds/bmc.tinkerbell.org_tasks.yaml (1)

Enhance schema validation and documentation.
The RBAC configuration schema could benefit from additional validation rules and documentation:
- Specify which properties are required
- Control additional properties
- Add descriptions for better documentation
- Add pattern validation for Kubernetes resource names

💡 Codebase verification
Schema validation missing for critical configuration values
The schema only validates RBAC settings but lacks validation for other important configuration values present in values.yaml:
- Container settings: image, imagePullPolicy
- Resource management: requests/limits for CPU and memory
- Deployment controls: deploy flag, additionalArgs
- Service configuration: serviceAccountName, leader election settings
- Node placement: nodeSelector, singleNodeClusterConfig
- Network configuration: hostNetwork
🔗 Analysis chain
Expand schema coverage for all configuration values.
The schema only covers RBAC configuration, but according to the summary, there are other important configuration values (e.g., deploy flag, resource requests/limits) that should also be validated. Consider adding schema validation for all supported configuration values.
Let me verify what other configuration values need schema validation:

🛠️ Refactor suggestion
Add input validation for URL construction.
The urlJoiner template should validate the input dictionary to prevent template rendering errors.
Consider adding validation:
{{- define "urlJoiner" }}
+{{- if not .urlDict.host }}
+{{- fail "Host is required in urlDict" }}
+{{- end }}
{{- if .urlDict.port }}
+{{- if or (lt (.urlDict.port | int) 1) (gt (.urlDict.port | int) 65535) }}
+{{- fail "Port must be between 1 and 65535" }}
+{{- end }}
{{- $host := printf "%v:%v" .urlDict.host .urlDict.port }}📝 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.

Add version pinning and checksum verification.
Downloading the latest tag without version pinning could lead to unexpected breaking changes. Consider:
- Pinning to specific versions
- Adding checksum verification for security

🛠️ Refactor suggestion
Fix IPv6 CIDR validation pattern.
The pattern uses \d which is incorrect in JSON schema patterns. Replace \d with [0-9]. Also, consider using a more maintainable approach by breaking down the pattern into smaller parts.
Consider using a library like ip-regex or breaking down the pattern into smaller, more maintainable parts.

Fix IPv4 CIDR validation pattern.
The current pattern allows invalid IPv4 addresses like 999.999.999.999. Consider using a more precise pattern that validates each octet to be between 0-255.

💡 Codebase verification
Cross-bundle dependency issue detected
Tinkerbell in distro-full.yaml declares a dependency on KubeOVN, but KubeOVN is defined in a separate bundle (paas-full.yaml) with no visible mechanism to combine these bundles. This could lead to deployment failures if the bundles are deployed independently, as there's no guarantee KubeOVN will be available when Tinkerbell requires it.
packages/core/platform/bundles/distro-full.yaml: Tinkerbell depends on KubeOVNpackages/core/platform/bundles/paas-full.yaml: KubeOVN is defined here, but no connection to distro-full bundle
🔗 Analysis chain
Verify dependency order for Tinkerbell deployment.
The dependencies look correct, but let's verify that kubeovn is properly listed in the bundle and deployed before Tinkerbell.
