Question
Which use case can be satisfied by cert-manager?
A. Scanning container images stored in Harbor
B. Adding certificates and certificate issuers as resource types in Kubernetes clusters
C. Routing requests based on HTTP headers
D. Generating certificates only by connecting to external services
Answer
The correct answer is B. cert-manager satisfies the use case of adding certificates and certificate issuers as resource types in Kubernetes clusters.
Explanation
cert-manager is a powerful and flexible tool that integrates with Kubernetes to provide automated certificate management. It extends Kubernetes by adding certificates and certificate issuers as first-class resource types in the cluster. This allows certificates to be requested and configured using native Kubernetes interfaces and APIs.
With cert-manager, you can define Certificate resources that specify the desired X.509 certificate. It then generates a private key, creates a Certificate Signing Request (CSR), and sends it to the configured Issuer for signing. cert-manager supports various built-in Issuer types, such as ACME (Let’s Encrypt), CA, Vault, and more. It can automatically obtain and renew certificates from these issuers.
The other options are not correct:
A. Scanning container images stored in Harbor is not a use case satisfied by cert-manager. Harbor is a separate tool for container image management.
C. Routing requests based on HTTP headers is typically handled by ingress controllers or service mesh solutions, not cert-manager.
D. cert-manager can generate certificates by connecting to external services, but it is not limited to only external services. It can also use built-in Issuer types.
In summary, cert-manager extends Kubernetes by adding certificates and certificate issuers as resource types, enabling automated certificate management within the cluster.
