- For Safety, install CRDs outside of Helm, e.g. kubectl
- For Ease of use, install CRDS with helm
helm install --name cert-manager --namespace cert-manager --version v1.1.0 jetstack/cert-manager --set installCRDs=true
https://artifacthub.io/packages/helm/cert-manager/cert-manager?modal=values
# Install the cert-manager CRDs, it is recommended to not use Helm to manage the CRDs installCRDs: false
Examples
v1.14.1
helm install --create-namespace --namespace cert-manager cert-manager jetstack/cert-manager --set installCRDs=true NAME: cert-manager LAST DEPLOYED: Tue Feb 6 16:35:49 2024 NAMESPACE: cert-manager STATUS: deployed REVISION: 1 TEST SUITE: None NOTES: cert-manager v1.14.1 has been deployed successfully! In order to begin issuing certificates, you will need to set up a ClusterIssuer or Issuer resource (for example, by creating a 'letsencrypt-staging' issuer). More information on the different types of issuers and how to configure them can be found in our documentation: https://cert-manager.io/docs/configuration/ For information on how to configure cert-manager to automatically provision Certificates for Ingress resources, take a look at the `ingress-shim` documentation: https://cert-manager.io/docs/usage/ingress/
