我在我的项目中使用 Azure devops 进行监管 CI/CD,我有一个通过 aks(azure kubernetes 服务)运行的 kubernetes 集群,我已经使用了 azure repo 和所有内容,并且每个必需的文件(即 azure-pipeline 文件和服务和部署)都是自动生成的,我没有更改其中的任何内容,它构建得很好,但在部署阶段失败,我遇到了这个错误,如下所示,
错误:

答案1
你收到此问题是因为你的 YAML 存在一些语法问题,主要是空格太多(如果你使用标签而不是空格,这也会产生 YAML 语法问题)。例如,
metadata:
name: alesblaze/bookstore
应该
metadata:
name: alesblaze/bookstore
子参数应位于第三个字母的级别。您可以根据以下信息编写 YAMLKubernetes 文档。我将在下面粘贴适当的 YAML。
在此之前,您必须知道为什么不能在某些参数中使用“/”。
即使 YAML 语法正确(你可以验证你的 yamls这里),还有其他验证。
apiVersion : apps/v1beta1
kind: Deployment
metadata:
name: alesblaze/bookstore
如果您将创建带有--dry-run
跳过某些验证的标志的部署,kubectl
则会创建此部署。
--dry-run
=false:如果为真,则仅打印要发送的对象,而不发送它。
$ kubectl create deployment alesblaze/bookstore --image=nginx --dry-run
deployment.apps/alesblaze/bookstore created (dry run)
但是,如果您想在所有验证中不使用此标志,您将收到错误:
$ 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
意味着 Kubernetes 中的部署名称、标签、选择器不能包含“/”因为它不会通过所有验证。您也遇到过类似的问题:
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 '/']
它描述于文档关于名字。
按照惯例,Kubernetes 资源名称的最大长度应为 253 个字符,并由小写字母数字字符、- 和 . 组成,但某些资源有更具体的限制。
其他资源喜欢image
或apiVersion
允许使用“/”。
下面 YAMLS 允许您创建部署和服务(具有适当的空格和允许的字符):
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
服务.yaml
apiVersion: v1
kind: Service
metadata:
name: alesblaze-bookstore
spec:
selector:
app: alesblaze-bookstore
ports:
- port: 8080
type: LoadBalancer
