- Kubernetes 1.24 is built with go1.18, which will no longer validate certificates signed with a SHA-1 hash algorithm by default. See https://golang.org/doc/go1.18#sha1 for more details. If you are using certificates like this in admission or conversion ([#109024](https://github.com/kubernetes/kubernetes/pull/109024), [@stlaz](https://github.com/stlaz))

- Kubernetes components that accepted X.509 client certificate authentication now read the user UID from a certificate subject name RDN with object ID `1.3.6.1.4.1.57683.2`. An RDN with this object ID had to contain a string value and appear no more than once in the certificate subject. Reading the user UID from this RDN could be disabled by setting the beta feature gate `AllowParsingUserUIDFromCertAuth` to `false`(until...

* Allows extension API server to dynamically discover the requestheader CA certificate when the core API server doesn't use certificate based authentication for it's clients ([#66394](https://github.com/kubernetes/kubernetes/pull/66394), [@rtripat](https://github.com/rtripat))

- Updated the control plane's trust anchor publisher to create and manage a new ClusterTrustBundle object, associated with the `kubernetes.io/kube-apiserver-serving` X.509 certificate signer. This ClusterTrustBundle contains a PEM bundle in its payload that you can use to verify kube-apiserver serving certificates.

It could be another container, for example with <a href="https://traefik.io/" class="external-link" target="_blank">Traefik</a>, handling **HTTPS** and **automatic** acquisition of **certificates**.

/// tip

Traefik has integrations with Docker, Kubernetes, and others, so it's very easy to set up and configure HTTPS for your containers with it.
