<p>I am installing linkerd helm verison with flux and cert mananger for tls rotation</p>
<p>cert manager holds default config so there isnt much to talk there</p>
<p>flux and linkerd with this config:</p>
<p>release.yaml</p>
<pre><code>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: &quot;2.11.2&quot;
      sourceRef:
        kind: HelmRepository
        name: linkerd
        namespace: linkerd
      interval: 1m
</code></pre>
<p>source.yaml</p>
<pre><code>---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: linkerd
  namespace: linkerd
spec:
  interval: 5m0s
  url: https://helm.linkerd.io/stable
</code></pre>
<p>linkerd-trust-anchor.yaml</p>
<pre><code>apiVersion: v1
data:
  tls.crt: base64encoded
  tls.key: base64encoded
kind: Secret
metadata:
  name: linkerd-trust-anchor
  namespace: linkerd
type: kubernetes.io/tls
</code></pre>
<p>which was created with:</p>
<pre><code>step certificate create root.linkerd.cluster.local ca.crt ca.key \
  --profile root-ca --no-password --insecure
</code></pre>
<p>issuer.yaml</p>
<pre><code>---
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
</code></pre>
<p>now when it comes the time to reconcile i get this error in the helmrelease</p>
<pre><code>Helm install failed: execution error at (linkerd2/templates/identity.yaml:19:21): Please provide the identity issuer certificate
</code></pre>
<p>however doing it manually does work perfectly</p>
<pre><code>helm install linkerd2   \
--set-file identityTrustAnchorsPEM=ca.crt   \
--set identity.issuer.scheme=kubernetes.io/tls   \
--set installNamespace=false   linkerd/linkerd2   \
-n linkerd
</code></pre>
<p>It Also work if I have the same setup but without cert manager and certificates declared manually (with a different secret name as linkerd will create it on its own)like this:</p>
<pre><code>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
</code></pre>
<p>Am I missing something?</p>

Diego Alejandro Llanos Gareca
<p>The problem lies here:</p>
<pre><code>values:
    identity.issuer.scheme: kubernetes.io/tls
</code></pre>
<p>It should be:</p>
<pre><code>values:
    identity:
      issuer:
        scheme: kubernetes.io/tls
</code></pre>
<p>Otherwise, helm wont recognize it and linkerd will think the schema is linkerd.io/tls, which doesn't match the schema structure of kubernetes secret tls.</p>
