1️⃣ Real-Time Diff Summary

Kind	Namespace	Name	Action
Namespace	demo-oss-japan	demo-oss-japan	CREATE
Service	demo-oss-japan	game-2048-dao-2048	CREATE
Deployment	demo-oss-japan	game-2048-dao-2048	CREATE
Application	argocd	game-2048	CREATE
AppProject	argocd	demo-oss-japan	CREATE

2️⃣ Impact Prediction

• The Deployment requires pods to be scheduled on nodes with label role=storage and tolerate taint with key=role, value=storage, effect=NoSchedule.
• Live cluster nodes do not have the label role=storage, making pods unschedulable on any nodes, so pods will remain Pending.
• Service is of type LoadBalancer; IP provisioning depends on cloud provider capabilities.

3️⃣ Risk Analysis

• Problem: Deployment containers run as root user violating Pod Security Standards (Restricted) Kyverno policy.
  Impact: Pod creation blocked by admission controller enforcing this policy, causing runtime failure.
  Mitigation: Enable runAsNonRoot: true and define non-root user in container securityContext.

• Problem: Deployment containers lack CPU and memory resource requests and limits, violating best practices Kyverno policy.
  Impact: Potential unstable resource allocation and scheduling issues.
  Mitigation: Define CPU and memory requests and limits for containers in Deployment.

1️⃣ Real-Time Diff Summary

Kind	Namespace	Name	Action
Namespace	(cluster-wide)	demo-oss-japan	CREATE
Deployment	demo-oss-japan	game-2048-dao-2048	CREATE
Service	demo-oss-japan	game-2048-dao-2048	CREATE
AppProject	argocd	demo-oss-japan	CREATE
Application	argocd	game-2048	CREATE

2️⃣ Impact Prediction

• The new namespace demo-oss-japan will be created.
• The game-2048-dao-2048 Deployment will schedule pods only to nodes labeled with role=storage and tolerate a matching NoSchedule taint with key role and value storage.
• The cluster has 3 nodes: 1 control-plane and 2 workers, none of which have the label role=storage. Hence the pods will be unschedulable and remain Pending.
• A service of type LoadBalancer will be created for external exposure, but the LoadBalancer IP may take time to be assigned.
• Kyverno policy violations:
  • Critical: The container is running as root user, which is disallowed by the enforced Pod Security Standards (Restricted).
  • Medium: The container lacks required CPU and memory resource requests and limits, violating best practices policies.
• These Kyverno violations will cause policy enforcement failure if mutations or validations are applied, blocking the Deployment from progressing.

3️⃣ Risk Analysis

• Problem: Deployment pods specify nodeSelector: role=storage but cluster nodes lack this label.
  Impact: Pods remain unschedulable indefinitely, causing application downtime.
  Mitigation: Add the label role=storage to one or more nodes intended to run these pods or remove/adjust the nodeSelector in Deployment spec.

• Problem: Pod runs container as root user, violating the cluster's Pod Security Standards (Restricted).
  Impact: Deployment blocked by Kyverno policy enforcement, preventing pod creation.
  Mitigation: Update Deployment pod security context to run as non-root user; e.g., set runAsNonRoot: true or specify a non-root user ID.

• Problem: CPU and memory resource requests and limits are missing from container spec.
  Impact: Deployment blocked or flagged by Kyverno best practices policy, potentially preventing scheduling or causing resource contention.
  Mitigation: Specify appropriate resources.requests and resources.limits for CPU and memory in pod spec.

• Problem: Target namespace demo-oss-japan does not exist in the live cluster and will be created.
  Impact: No immediate risk; however, downstream namespace-specific policies or ResourceQuotas should be checked after namespace creation.
  Mitigation: Confirm intended namespace creation and apply any necessary quota or policy configurations post-creation.

Deployment	demo-oss-japan	game-2048-dao-2048	CREATE
AppProject	argocd	demo-oss-japan	CREATE
Application	argocd	game-2048	CREATE

2️⃣ Impact Prediction

• The namespace demo-oss-japan does not currently exist in the live cluster but will be created by the manifest.
• The Service of type LoadBalancer will provision an external IP but may require time for the LoadBalancer IP to be ready.
• Deployment pod will be scheduled on nodes labeled with role=storage.
• Nodes in the cluster are labeled with roles: control-plane and none; none have no role label role=storage. This leads to no nodes matching the nodeSelector role=storage.
• Hence, the deployment pods will be unschedulable and remain in Pending state due to nodeSelector mismatch.
• Tolerations specified are valid but irrelevant because no node matches the nodeSelector.
• Kyverno policy enforcement failed:
  • Privilege escalation is disallowed but the deployment's securityContext lacks an explicit allowPrivilegeEscalation set to false, causing rejection.
  • CPU and memory resource requests and limits are missing from the containers, violating best practices policy.

3️⃣ Risk Analysis

• Problem: Deployment pods have nodeSelector role=storage but no nodes in cluster have that label.
  Impact: Pods will remain in Pending state indefinitely due to no matching nodes for scheduling.
  Mitigation: Remove or correct the nodeSelector to match existing node labels or label nodes appropriately.

• Problem: Deployment lacks explicit allowPrivilegeEscalation setting; Kyverno policy disallows privilege escalation.
  Impact: Pod admission will be denied, blocking pod creation and deployment functionality.
  Mitigation: Add securityContext: allowPrivilegeEscalation: false to container spec to comply with the policy.

• Problem: Deployment containers do not specify CPU and memory resource requests and limits.
  Impact: Kyverno policy rejects the pod creation, blocking deployment.
  Mitigation: Define explicit CPU and memory resource requests and limits for containers in the deployment.

• Problem: Namespace demo-oss-japan does not currently exist in live cluster.
  Impact: Resources targeting this namespace cannot be created until the namespace exists.
  Mitigation: The manifest creates the namespace, so ensure namespace creation is prioritized before other resources deploy.

1️⃣ Real-Time Diff Summary

Kind	Namespace	Name	Action
Namespace		demo-oss-japan	CREATE
Service	demo-oss-japan	game-2048-dao-2048	CREATE
Deployment	demo-oss-japan	game-2048-dao-2048	CREATE

2️⃣ Impact Prediction

• The new namespace demo-oss-japan will be created.
• The Helm chart dao-2048 version 1.2.1 will deploy a Deployment and a LoadBalancer Service named game-2048-dao-2048 in the demo-oss-japan namespace.
• The Deployment's pod has resource requests and limits of 100m CPU and 128Mi memory.
• The Service is of type LoadBalancer, so external IP allocation may take some time after deployment.
• Security context disables privilege escalation for the container, enhancing security.
• Since the namespace does not currently exist in the live cluster, the workload have no existing resources and environment impact yet.

3️⃣ Risk Analysis

• Problem: Target namespace demo-oss-japan does not currently exist in the live cluster.
  Impact: The Application resources cannot be created before the namespace creation completes, causing deployment block.
  Mitigation: Create namespace demo-oss-japan in the cluster before or as part of the deployment.

• No Kyverno policy violations detected on the rendered manifest resources.

• No resource quota found for demo-oss-japan, no quota violations expected.

• No scheduling constraints detected; cluster nodes available and ready.

• All referenced ConfigMaps, Secrets, and PVCs are either non-existent or not used, so no missing dependencies detected.
