如何修复错误：必须在Helm中提供名称或指定--generate name

创建示例helm图表名称为my图表，并使用nginx服务编写deployment.yaml、service.yaml、ingress.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx
spec:
  ports:
  - name: main
    port: 80
    protocol: TCP
    targetPort: 80
  selector:
    app: nginx

apiVersion: extensions/v1beta2
kind: Deployment
metadata:
  name: nginx
spec:
  replicas: 3
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:1.13
          ports:
              containerPort: 80

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx
  annotations:
    http.port: "443"
spec:
    backend:
        serviceName: nginx
        servicePort: 80

预期输出：......状态：已部署

Answer 1

在helm v3中，您可以使用：

helm install [NAME] [CHART]

或者：

helm install [CHART] --generate-name

例子：

helm install reloader stakater/reloader
helm install stakater/reloader --generate-name

来自帮助手册：

helm install --help
Usage:
  helm install [NAME] [CHART] [flags]
Flags:
  -g, --generate-name            generate the name (and omit the NAME parameter)

Answer 2

只需添加——在helm命令末尾生成name

Answer 3

根据v3. x的舵手留档

helm install --help
Usage:
helm install [NAME] [CHART] [flags]

您想使用：
helm安装“您的发布名称”图表

例如：

# helm repo add stable https://kubernetes-charts.storage.googleapis.com/
# helm install wordpress-helm-testing stable/wordpress 
NAME: wordpress-helm-testing
LAST DEPLOYED: 2019-10-07 15:56:21.205156 -0700 PDT m=+1.763748029
NAMESPACE: default
STATUS: deployed
NOTES:
1. Get the WordPress URL:

  NOTE: It may take a few minutes for the LoadBalancer IP to be available.
        Watch the status with: 'kubectl get svc --namespace default -w wordpress-helm-testing'
  export SERVICE_IP=$(kubectl get svc --namespace default wordpress-helm-testing --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
  echo "WordPress URL: http://$SERVICE_IP/"
  echo "WordPress Admin URL: http://$SERVICE_IP/admin"

2. Login with the following credentials to see your blog

  echo Username: user
  echo Password: $(kubectl get secret --namespace default wordpress-helm-testing -o jsonpath="{.data.wordpress-password}" | base64 --decode)


#helm list
NAME                    NAMESPACE   REVISION    UPDATED                                 STATUS      CHART          
wordpress-helm-testing  default     1           2019-10-07 15:56:21.205156 -0700 PDT    deployed    wordpress-7.3.9

这是一种更好的操作方法，因为它消除了版本名称中的随机性。您可能希望使用用户名或任何使其独特并为版本增加意义的东西，而不是--gence-name选项将为您提供的GUID。
