Kubernetes HTTPS with cert-manager and Let's Encrypt
Source: YouTube · Kubesimplify · published Feb 24, 2023 · 25:32
This video explains HTTPS fundamentals, public/private key encryption, and Certificate Authorities, demonstrating TLS implementation in Kubernetes using self-signed certs and automated Let's Encrypt certificates via cert-manager 0:10-0:25.
Key Takeaways:
• HTTPS Flow: A client verifies the server's certificate against a Certificate Authority before establishing an encrypted connection using a shared session key 1:11-2:04.
• Certificate Authorities: CAs like Let's Encrypt issue trusted certificates. Tools like Certbot use the ACME protocol to automate certificate generation, renewal, and revocation 5:20-8:16.
• Self-Signed Setup: For development, generate key pairs with OpenSSL, create a Kubernetes TLS secret, and configure an Ingress, though browsers flag the connection as untrusted 10:50-14:50.
• Cert Manager Automation: In production, cert-manager creates a ClusterIssuer for Let's Encrypt, manages ACME challenges, and injects valid certificates into Ingress resources 16:19-20:19.
HTTPS is essential for security, and cert-manager provides a robust, automated solution for managing certificates in Kubernetes clusters.

https we all want it and we all should be using it whether for demos and obviously for production applications in this video I'll be going through all the concepts of https what is the certificate Authority how it works how we can actually generate certificates self-signed certificates and using a certificate Authority for kubernetes cluster and deploy a sample application and get https for it so without wasting any time let's get started but before that a huge thanks to Commodore of Asia cystic instructor slim AI who are the members and they support my work and that is why I am able to produce this content but there is nothing about them in this video this video is all about sdbs Ingress kubernetes TLS certificate Authority and everything so let's get started so first we'll get through th…
