NAMESPACE=demo
kubectl get ns $NAMESPACE -o json | jq '.spec.finalizers=[]' > ns.json
kubectl proxy --port=8899 &
PID=$!
curl -X PUT http://localhost:8899/api/v1/namespaces/$NAMESPACE/finalize -H "Content-Type: application/json" --data-binary @ns.json
kill $PID這段代碼的含義是在 Kubernetes 環(huán)境中刪除一個(gè)命名空間（Namespace）及其關(guān)聯(lián)的資源，包括在命名空間中運(yùn)行的所有容器、服務(wù)、持久卷等。讓我們逐行解釋代碼的作用：
-
NAMESPACE=demo這一行指定了要?jiǎng)h除的命名空間的名稱，代碼中將其設(shè)置為 "demo"。你可以根據(jù)需要將 "demo" 替換為你要?jiǎng)h除的特定命名空間的名稱。 -
kubectl get ns $NAMESPACE -o json | jq '.spec.finalizers=[]' > ns.json這一行代碼使用 kubectl 命令獲取指定命名空間的詳細(xì)信息，并將其以 JSON 格式輸出。然后通過 jq 工具（一個(gè)命令行 JSON 處理工具）將.spec.finalizers的值設(shè)置為空數(shù)組，這樣做的目的是將命名空間中的 finalizer 清空。finalizer 是用于在刪除命名空間時(shí)執(zhí)行清理操作的機(jī)制。 -
kubectl proxy --port=8899 &這一行代碼啟動(dòng)了一個(gè) kubectl 代理服務(wù)器，并監(jiān)聽在本地的 8899 端口上。代理服務(wù)器的目的是允許后續(xù)的 curl 請(qǐng)求與 Kubernetes API 進(jìn)行交互，從而繞過直接與集群通信的需求。 -
PID=$!這一行代碼將 kubectl 代理服務(wù)器的進(jìn)程 ID 存儲(chǔ)在變量 PID 中。這樣做是為了在后續(xù)操作中能夠終止該進(jìn)程，以便清理代理服務(wù)器。 -
curl -X PUT http://localhost:8899/api/v1/namespaces/$NAMESPACE/finalize -H "Content-Type: application/json" --data-binary @ns.json這一行代碼使用 curl 命令向 Kubernetes API 發(fā)出 PUT 請(qǐng)求，調(diào)用命名空間的 finalize 操作。在這個(gè)請(qǐng)求中，通過將之前生成的 ns.json 文件的內(nèi)容作為請(qǐng)求體，來執(zhí)行對(duì)命名空間的最終清理。由于之前已經(jīng)將 finalizer 清空，這個(gè)操作將立即刪除命名空間和其所有資源。 -
kill $PID最后，這一行代碼終止之前啟動(dòng)的 kubectl 代理服務(wù)器，釋放占用的端口和資源。文章來源：http://www.zghlxwxcb.cn/news/detail-610166.html
需要注意的是，這段代碼執(zhí)行時(shí)需要確保當(dāng)前的環(huán)境配置有足夠的權(quán)限來刪除命名空間及其資源，否則可能會(huì)失敗。同時(shí)，謹(jǐn)慎使用這樣的代碼，因?yàn)閯h除命名空間將導(dǎo)致其中的所有資源永久丟失，無法恢復(fù)。在生產(chǎn)環(huán)境中，務(wù)必謹(jǐn)慎執(zhí)行類似的操作，并確認(rèn)執(zhí)行之前的后果。文章來源地址http://www.zghlxwxcb.cn/news/detail-610166.html
