获取ValidationError(Deployment.spec)：在io.k8s.api.apps.v1.DeploymentSpec中缺少所需字段“选择器”
获取ValidationError(Deployment.spec)：在io.k8s.api.apps.v1.DeploymentSpec中缺少所需字段“选择器”
提问于 2021-04-25 18:53:06
我在这里错误地提到了类似的问题：ValidationError:在io.k8s.api.v1.DeploymentSpec中缺少必需字段“选择器”
我将apiVersion，即apiVersion: apiVersion/v1beta 1改为apiVersion: app/v1，我使用的是kubeadm和运行工作者的3个节点。
然而，在我的yaml中，我确实有匹配的标签选择器
labels:
app: rabbitmq
role: master
tier: queue如果我尝试运行以下yaml部署：
部署"rabbitmq“无效：
- spec.selector:必需值
- spec.template.metadata.labels:无效值:映射字符串{“app”：“rabbitmq”，“角色”：“主”，“层”：“队列”}：
selector与模板labels不匹配

您缺少了selector:字段在Deployment.spec下。目前，只有replicas:和template:在那里。
来自部署文档的示例
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
labels:
app: nginx
spec:
replicas: 3
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
