The Kubernetes Specialist path
The cluster path. You cover the Linux and networking Kubernetes is built on, then containers, core objects, configuration, storage, debugging, packaging, delivery and cluster security, with probe, secret and resource incidents to prove it.
Who it is for
Engineers who run workloads on Kubernetes day to day, and anyone preparing for CKA or CKAD style work.
