部署到 aks 時讀取配置時出錯

我在我的項目中使用 Azure devops 來管理 CI/CD，我有一個通過 aks（azure kubernetes 服務）執行的 kubernetes 集群，我使用了 azure repo 和所有東西，以及每個需要的文件（即 azure-pipeline 文件和服務以及部署）是自動生成的，我沒有更改任何內容，它建構得很好，但在部署階段失敗，我遇到這個錯誤，如下所示，

錯誤：

編輯 ：

服務.yaml

   name: alesblaze/bookstore
spec:
   type: LoadBalancer
   ports:
   - port: 8080 
   selector:
       app: alesblaze/bookstore

部署.yaml

apiVersion : apps/v1beta1
kind: Deployment
metadata:

spec:
 replicas: 1
 template:
   metadata:
     labels:
       app: alesblaze/bookstore

         ports:
         - containerPort: 8080

Kubernetes 版本：1.13.10

您收到此問題是因為您的 YAML 存在一些語法問題，主要是空格過多（如果您使用TAB代替空格，也會產生 YAML 語法問題）。例如，而不是

metadata:
   name: alesblaze/bookstore

應該

metadata:
 name: alesblaze/bookstore

子參數應該在第三個字母的級別。您可以將 YAML 建立在Kubernetes doc上。我將在下面粘貼正確的 YAML。
在此之前，您必須知道為什麼不能在某些參數中使用“/”。

即使 YAML 語法是正確的（您可以在此處驗證您的 yaml ），也有其他驗證。

apiVersion : apps/v1beta1
kind: Deployment
metadata:
 name: alesblaze/bookstore

如果您將使用--dry-run跳過某些驗證的標誌創建部署，則將創建kubectl此部署。

--dry-run=false：如果為真，只列印要發送的對象，不發送。

$ kubectl create deployment alesblaze/bookstore --image=nginx --dry-run
deployment.apps/alesblaze/bookstore created (dry run)

但是，如果您想在沒有此標誌的情況下使用它進行所有驗證，您將收到錯誤：

$ kubectl create deployment alesblaze/bookstore --image=nginx
The Deployment "alesblaze/bookstore" is invalid: 
* metadata.name: Invalid value: "alesblaze/bookstore": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')
* metadata.labels: Invalid value: "alesblaze/bookstore": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')
* spec.selector.matchLabels: Invalid value: "alesblaze/bookstore": a valid label must be an empty string or consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyValue',  or 'my_value',  or '12345', regex used for validation is '(([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9])?')
* spec.selector: Invalid value: v1.LabelSelector{MatchLabels:map[string]string{"app":"alesblaze/bookstore"}, MatchExpressions:[]v1.LabelSelectorRequirement(nil)}: invalid label selector

表示 Kubernetes 中的部署名稱、標籤、選擇器不能包含**“/”**，因為它不會通過所有驗證。您收到了類似的問題：

Object: &{map["apiVersion":"apps/v1beta1" "kind":"Deployment" "metadata":map["annotations":map["kubectl.kubernetes.io/last-applied-configuration":""] "name":"alesblaze/bookstore" "namespace":"default"] "spec":map["replicas":'\x01' "template":map["metadata":map["labels":map["app":"alesblaze/bookstore"]] "spec":map["containers":[map["image":"***/alesblaze/bookstore" "name":"alesblaze/bookstore" "ports":[map["containerPort":'\u1f90']]]] "imagePullSecrets":[map["name":"bookstoreappacrd0a8-auth"]]]]]]}
from server for: "/home/vsts/work/_temp/bookstore_1570774284000": invalid resource name "alesblaze/bookstore": [may not contain '/']

它在有關名稱的文件中進行了描述。

按照慣例，Kubernetes 資源的名稱最長不得超過 253 個字元，並且由小寫字母數字字元、- 和 . 組成，但某些資源有更具體的限制。

其他資源喜歡image或apiVersion允許使用**"/"**。

在 YAMLS 下方，您可以創建部署和服務（使用適當的空格和允許的字元）：

部署.yaml

apiVersion : apps/v1beta1
kind: Deployment
metadata:
 name: alesblaze-bookstore
spec:
 replicas: 1
 template:
   metadata:
     labels:
       app: alesblaze-bookstore
   spec:
     containers:
     - name: alesblaze-bookstore 
       image: bookstoreappacr.azurecr.io/alesblaze/bookstore 
       ports:
       - containerPort: 8080

服務.yaml

apiVersion: v1
kind: Service
metadata:
 name: alesblaze-bookstore
spec:
 selector:
   app: alesblaze-bookstore
 ports:
 - port: 8080 
 type: LoadBalancer
