Kubernetes 解组器OrderCoder:数量必须与正则表达式匹配

当我使用这个命令安装CoreDNS时，顺便说一句，OS版本是：CentOS 7.6，Kubernetes版本是：v1.15.2：

kubectl create -f coredns.yaml

输出为：

[root@ops001 coredns]# kubectl create -f coredns.yaml
serviceaccount/coredns created
clusterrole.rbac.authorization.k8s.io/system:coredns created
clusterrolebinding.rbac.authorization.k8s.io/system:coredns created
configmap/coredns created
service/kube-dns created

这是我的coredns.yaml：

我遗漏了什么吗？

请参考您的部署中的

限制{“内存”：“\uuuu支柱\uuuu DNS\uuuu内存\uuu限制”

如文档中所述，在从kube dns切换到COREDNS时，您可以使用

自己的脚本

覆盖某些参数，因为存在

部署脚本

安装

在Kubernetes版本1.13及更高版本中，CoreDNS功能门被删除，默认情况下使用CoreDNS。 因此，您可以使用原始安装并在配置映射和部署中查看默认值

希望这有帮助

kubectl get configmap coredns -n kube-system -o yaml
