Self-signed certificate

As explained in Kubernetes for Developers

A self-signed certificate is a certificate signed by its own subject rather than by a trusted certificate authority.

How Kubernetes for Developers covers it

How deep it goes

Explains certificate creation, Kubernetes Secret storage, Ingress configuration, DNS mapping, and browser warnings.

Examples

Uses OpenSSL commands, a my-tls-cert Secret, an example.com Ingress, and a local hosts-file mapping.

What it assumes

Assumes basic Kubernetes networking context while teaching certificate files, TLS Secrets, and Ingress references.

What you can do after

Apply it via OpenSSL, kubectl, and an Ingress configuration to expose an encrypted endpoint.

How it connects

Connects TLS with certificate authorities, Kubernetes Secrets, Ingress, HTTPS, and DNS.
