kubernetes - 解析 templates/deployment.yaml 时出错 : json: line 1: invalid character '{' looking for beginning of object key string

Question

当我尝试使用 Kubernetes 部署 Nexus 时，出现以下错误。

命令: kubectl appy -f templates/deployment.yaml

error parsing templates/deployment.yaml: json: line 1: invalid character '{' looking for beginning of object key string

您此处提供的模板是 Helm Chart 的一部分，可以使用 helm-cli 进行部署，而不是使用 kubectl apply。
