What can you use to dynamically make Kubernetes resources discoverable topublic DNS servers?
Correct Answer: A
Explanation Setting up ExternalDNS for Oracle Cloud Infrastructure (OCI): Inspired by Kubernetes DNS, Kubernetes' cluster-internal DNS server, ExternalDNS makes Kubernetes resources discoverable via public DNS servers. Like KubeDNS, it retrieves a list of resources (Services, Ingresses, etc.) from the Kubernetes API to determine a desired listof DNS records. In a broader sense, ExternalDNS allows you to control DNS records dynamically via Kubernetes resources in a DNS provider-agnostic way Deploy ExternalDNS Connect your kubectl client to the cluster you want to test ExternalDNS with. We first need to create a config file containing the information needed to connect with the OCI API. Create a new file (oci.yaml) and modify the contents to match the example below. Be sure to adjust the values to match your own credentials: auth: region:us-phoenix-1 tenancy: ocid1.tenancy.oc1... user: ocid1.user.oc1... key: | -----BEGIN RSA PRIVATE KEY----- -----END RSA PRIVATE KEY----- fingerprint: af:81:71:8e... compartment: ocid1.compartment.oc1...
