⎈ A cert-manager webhook for DuckDNS, SaaS with Kubernetes operators, Next-generation cloud control plane, Cilium cheat sheet

This newsletter is brought to you by Loft Labs to announce the launch of Multitenancy March

---

We are partnering up with Loft Labs (the creator of vCluster) for Multitenancy March — an event dedicated to celebrating multi-tenancy in Kubernetes!

We have been working on it for a while, and this is what you can expect:

• Deep dives into Kubernetes and multi-tenancy.

• Hands-on workshops with real experts (Saiyam!)

• My thoughts on multi-tenancy :)

The event is completely free, and you can sign up here.
