<p>I have k8s cluster with version 1.21 and cert-manager (v0.12) which was installed via helm. As far as I understand I should upgrade cert-manager version-by-version but I can't find CRDs file for version 0.13 (<a href="https://github.com/cert-manager/cert-manager/releases/download/v0.13/cert-manager.crds.yaml" rel="nofollow noreferrer">https://github.com/cert-manager/cert-manager/releases/download/v0.13/cert-manager.crds.yaml</a> - there is no such file. CRDs were installed separately from cert-manager).
So, guys, help me!</p>

<p>I can get a file from this <a href="https://github.com/jetstack/cert-manager/releases/download/v0.13.0/cert-manager.yaml" rel="nofollow noreferrer">URL</a>; please test it and let me know how it works. When upgrading from earlier versions, use this file, which contains all of the Custom Resource Definitions (CRDs) for cert-manager 0.13.</p>
<p>You can upgrade using static manifests also by running the below command:</p>
<pre><code>kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/&lt;version&gt;/cert-manager.yaml
</code></pre>
<p>You can find more information in this <a href="https://cert-manager.io/docs/installation/upgrading/#upgrading-using-static-manifests" rel="nofollow noreferrer">doc</a>.</p>
