This video demonstrates how to use Cert-Manager to automate certificate management in Kubernetes clusters 0:00.
Key Takeaways:
• Cert-Manager simplifies obtaining and renewing certificates from sources like Let's Encrypt, private PKI, and self-signed CAs 0:06
• The video covers five practical examples: creating self-signed certificates, using CA issuers, setting up Grafana, HTTP-01 challenge, and DNS-01 challenge 1:16
• A demonstration shows how unencrypted HTTP traffic exposes credentials through packet capture, while TLS encryption prevents this 20:40
• The video provides detailed debugging steps when certificate issuance fails, showing how to trace from certificate to certificate request to order and challenge 27:38
• DNS-01 challenge setup requires creating IAM roles, policies, and proper Route 53 configuration for Let's Encrypt to verify domain ownership 31:25
The video concludes with a Grafana dashboard showing all certificates and their expiration dates, enabling proper monitoring and alerting for certificate renewals 42:21.

search manager adds certificates and certificate issues as a custom resource types in the kubernetes cluster it simplifies the process of obtaining renewing and using those certificates search manager can issue certificates from a variety of supported sources including let's encrypt hershey corp fault vinafi as well as private pki the typical workflow will look like this you create a certificate easier for example let's encrypt when you create an ingress for your service you will specify in the annotation that you want to use that let's encrypt easier to secure your ingress when you apply the search manager will detect that annotation and issue a certificate from let's encrypt and store it in the kubernetes secret that ingress can use search manager provides custom resource issuer that nam…
