[TIL] 쿠버네티스 Fluentd.yaml 배포 시 오류 2가지 : no matches for kind "" in version "", Error from server (BadRequest) : DaemonSet in version "v1" cannot be handled as a DaemonSet

아래 글을 보고 따라서 쿠버네티스 EFK 스택을 구성하다가 다음과 같은 오류가 났다.

$ kubectl apply -f fluentd.yaml
serviceaccount/fluentd unchanged
[resource mapping not found for name: "fluentd" namespace: "kube-system" from "fluentd.yaml": no matches for kind "ClusterRole" in version "rbac.authorization.k8s.io/v1beta1"
ensure CRDs are installed first, resource mapping not found for name: "fluentd" namespace: "" from "fluentd.yaml": no matches for kind "ClusterRoleBinding" in version "rbac.authorization.k8s.io/v1beta1"
ensure CRDs are installed first]
Error from server (BadRequest): error when creating "fluentd.yaml": DaemonSet in version "v1" cannot be handled as a DaemonSet: json: cannot unmarshal number into Go struct field EnvVar.spec.template.spec.containers.env.value of type string

두가지 오류로 볼 수 있는데

 

먼저 첫번째 경우

[resource mapping not found for name: "fluentd" namespace: "kube-system" from "fluentd.yaml": no matches for kind "ClusterRole" in version "rbac.authorization.k8s.io/v1beta1"
ensure CRDs are installed first, resource mapping not found for name: "fluentd" namespace: "" from "fluentd.yaml": no matches for kind "ClusterRoleBinding" in version "rbac.authorization.k8s.io/v1beta1"
ensure CRDs are installed first]

Fluentd.yaml 문서에서 ClusterRole의 버전을 rbac.authorization.k8s.io/v1beta1에서 rbac.authorization.k8s.io/v1로 변경해주면 된다.

 

두번째 경우

Error from server (BadRequest): error when creating "fluentd.yaml": DaemonSet in version "v1" cannot be handled as a DaemonSet: json: cannot unmarshal number into Go struct field EnvVar.spec.template.spec.containers.env.value of type string

Fluentd.yaml문서에 env안의 value: 9200를 value: "9200"으로 변경해주면 된다.
