Kubernetes Policy and Kiverno Speaking Practice one Professional Caverno and Policy Governance Kiverno allows us to implement a guarded playground for developers while maintaining full administrative control over the cluster.

Kubernetes Policy 和 Kiverno 實戰練習一：專業的 Caverno 和 Policy Governance

By defining what users can and cannot do through policies, we effectively eliminate common misconfigurations at the source.

Kiverno 讓我們能為 developers 建立一個 guarded playground，同時保有對 cluster 的完全 administrative control。

The beauty of Kyverno is that it doesn't require learning a new language.

我們透過定義 users 可以做什麼、不能做什麼的 policies，從 source 端就有效杜絕常見的 misconfigurations。

If you know YAML, you can write policies.

Kyverno 最棒的地方就是，你不需要學習新的語言。

We use admission controllers to ensure that not even a single misconfiguration becomes a vector for potential hackers.

只要你會 YAML，就能寫出 policies。

PL policy based orchestration helps us manage the complexity that arises when hundreds of developers are touching the cluster.

我們利用 admission controllers，確保連一個 misconfiguration 都無法成為 hackers 的 potential vector。

PL policy-based orchestration 幫助我們管理當數百名 developers 操作 cluster 時所產生的 complexity。

Security and compliance Enforcement we need to enforce policies that prevent pods from running as root or pulling images from unauthorized public repositories.

Workloads should only be able to use base images that have been explicitly blessed by our infrastructure and security teams.

Security 和 compliance Enforcement：我們需要 enforce policies，防止 pods 以 root 權限執行，或是從未經授權的 public repositories 拉取 images。

If a zero day vulnerability is discovered in a base image, we can instantly yank it from our allowed list in the config map.

Workloads 應該只能使用被我們的 infrastructure 和 security teams 明確核准的 base images。

Our validate policies use the any not operator to allow for flexible wildcards while maintaining strict security boundaries.

我們的 validate policies 使用 any not operator，讓萬用字元更具彈性，同時維持嚴格的安全界線。

Caverno acts as our last mile of defense to ensure every pod adheres to the rules defined by our security leadership.

Kiverno 作為我們最後一道防線，確保每個 pod 都遵守我們安全領導團隊定義的規則。

資源優化與 Guardrails：不應允許任何單一 workload 預留叢集中的所有可用資源，導致其他程序停擺。

Resource optimization and Guardrails no single workload should be allowed to reserve all available resources in the cluster and starve other processes.

我們利用 mutation policies，將 GPU 特定 workload 自動導向正確的節點群組。

We utilize mutation policies to automatically route GPU specific workloads to the correct node groups.

標準 CPU workload 除非應用程式特別要求，否則絕不應導向昂貴的 GPU 節點。

Standard CPU workloads should never be routed to expensive GPU nodes unless specifically required by the application.

透過 policies 自動化節點親和性，我們能減少資源競爭，並避免鄰居幹擾問題。

By automating node affinity through policies, we minimize resource contention and prevent noisy neighbor issues.

我們的目標是提供一個自助服務環境，同時確保所有自動化部署都遵循安全最佳實踐。

Our goal is to provide a self service environment while ensuring that all automated deployments follow security best practices.

技術疑難排解與策略：外部變數讓 Kiverno 能夠隨時掌握叢集的目前狀態與可用的運算選項。

Technical troubleshooting and Strategy External variables allow Caverno to stay aware of the cluster's current state and available compute options.

Preempting a workload that has been running for hours can lead to significant wasted infrastructure costs and human effort.

長時間執行的工作負載被搶佔，可能會造成基礎設施成本和人力的大量浪費。

We use patches JSON6902 to perform precise surgery on resource manifests at runtime during the admission phase.

我們使用 JSON6902 patch 在 admission 階段執行時，對資源 manifest 進行精確的修改。

Integrated reporting is crucial because simply having a policy isn't enough you must be able to visualize what is failing.

整合報告非常重要，因為光有 Policy 不夠，你還必須能視覺化哪些地方出錯。

We need to evaluate a hybrid cloud strategy to guard against regional outages and ensure compute availability for critical tasks.

我們要評估混合雲策略，以防區域性中斷，並確保關鍵任務的運算可用性。
