# Technical Marketing Site cert-manager.io

cert-manager is a powerful and extensible X.509 certificate controller for Kubernetes and OpenShift workloads. It will obtain certificates from a variety of Issuers, both popular public Issuers as well as private Issuers, and ensure the certificates are valid and up-to-date, and will attempt to renew certificates at a configured time before expiry. CNCF-hosted and 100% open-source. We worked with the cert-manager contributors and the marketing team from Jetstack to develop the new cert-manager site and documentation with Next.js. Testing and deployment was done through Netlify.

cert-manager is a powerful and extensible X.509 certificate controller for
Kubernetes and OpenShift workloads. It will obtain certificates from a variety
of Issuers, both popular public Issuers as well as private Issuers, and ensure
the certificates are valid and up-to-date, and will attempt to renew
certificates at a configured time before expiry.

We worked with the cert-manager contributors and the Jetstack marketing team to
develop their new site based on given designs. For the documentation we modified
and implemented
[Next Product Docs](https://github.com/zentered/next-product-docs), an open
source solution to render
[Markdown documentation as a static site](https://zentered.co/articles/product-documentation-with-nextjs/)
with features such as Search, Table of Contents, etc. We also helped with the
deployment pipeline to Netlify.
