Web / Traefik Interview questions

What is the purpose of Let's Encrypt integration in Traefik?

Traefik integrates with Let's Encrypt through ACME (Automatic Certificate Management Environment) so it can request, validate, and renew TLS certificates automatically, without an operator manually generating and rotating them.

A certificate resolver is configured with the ACME settings (email, challenge type, storage location), and routers reference that resolver in their TLS section to get an auto-issued certificate for their host.

This removes one of the most common sources of production outages, expired certificates, since Traefik tracks expiry and renews well ahead of time on its own.
