与Linkerd和Cert Manager的Flux有发行人错误

Question

我正在使用Flux和Cert Mananger安装Linkerd Helm Verison，for TLS rotation

，在其中flux and linkerd config没有太多内容

Cert Manager拥有默认配置，因此使用此config：

repartion.yaml

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: linkerd
  namespace: linkerd
  
spec:
  interval: 5m
  values:
    identity.issuer.scheme: kubernetes.io/tls
    installNamespace: false
    
  valuesFrom:
  - kind: Secret
    name: linkerd-trust-anchor
    valuesKey: tls.crt
    targetPath: identityTrustAnchorsPEM
  chart:
    spec:
      chart: linkerd2
      version: "2.11.2"
      sourceRef:
        kind: HelmRepository
        name: linkerd
        namespace: linkerd
      interval: 1m

source.yaml

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: linkerd
  namespace: linkerd
spec:
  interval: 5m0s
  url: https://helm.linkerd.io/stable

linkerd-trust-trust-andor.yaml

apiVersion: v1
data:
  tls.crt: base64encoded
  tls.key: base64encoded
kind: Secret
metadata:
  name: linkerd-trust-anchor
  namespace: linkerd
type: kubernetes.io/tls

。 ：

step certificate create root.linkerd.cluster.local ca.crt ca.key \
  --profile root-ca --no-password --insecure

issuer.yaml

---
apiVersion: cert-manager.io/v1
kind: Issuer
metadata:
  name: linkerd-trust-anchor
  namespace: linkerd
spec:
  ca:
    secretName: linkerd-trust-anchor
---
apiVersion: cert-manager.io/v1
kind: Certificate
metadata:
  name: linkerd-identity-issuer
  namespace: linkerd
spec:
  secretName: linkerd-identity-issuer
  duration: 48h
  renewBefore: 25h
  issuerRef:
    name: linkerd-trust-anchor
    kind: Issuer
  commonName: identity.linkerd.cluster.local
  dnsNames:
  - identity.linkerd.cluster.local
  isCA: true
  privateKey:
    algorithm: ECDSA
  usages:
  - cert sign
  - crl sign
  - server auth
  - client auth

现在现在是时候调和时，我会在helmrelease中遇到此错误，

Helm install failed: execution error at (linkerd2/templates/identity.yaml:19:21): Please provide the identity issuer certificate

但是手动做得很好

helm install linkerd2   \
--set-file identityTrustAnchorsPEM=ca.crt   \
--set identity.issuer.scheme=kubernetes.io/tls   \
--set installNamespace=false   linkerd/linkerd2   \
-n linkerd

，如果我有相同的设置，但没有手动声明的证书和证书（带有不同的秘密名称为Linkerd会自己创建它）这样：

valuesFrom:
  - kind: Secret
    name: linkerd-trust-anchor
    valuesKey: tls.crt
    targetPath: identityTrustAnchorsPEM
  - kind: Secret
    name: linkerd-identity-issuer-2
    valuesKey: tls.crt
    targetPath: identity.issuer.tls.crtPEM
  - kind: Secret
    name: linkerd-identity-issuer-2
    valuesKey: tls.key
    targetPath: identity.issuer.tls.keyPEM

我错过了什么吗？

Answer 1

问题在这里：

values:
    identity.issuer.scheme: kubernetes.io/tls

应该是：

values:
    identity:
      issuer:
        scheme: kubernetes.io/tls

否则，Helm不会认识到它，Linkerd会认为该模式是Linkerd.io/tls，它与Kubernetes Secret TLS的模式结构不符。
