Cert-Manager Configuration
The cert-manager package adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates.
Best Practice
Any package configuration options listed under Reference/Packages should be modified through package yaml files (with kind: Package) through command eksctl anywhere apply package -f packageFileName. Modifying objects outside of package yaml files may lead to unpredictable behaviors.
