How do you pronounce etcd (Kubernetes key-value store)?
etcd is pronounced 'ET-seed' (/ˈɛtsiːd/). The name comes from '/etc' (Unix config directory) + 'd' (distributed). It is the distributed key-value store that Kubernetes uses as its backing data store. Think: the distributed /etc directory — 'ET-seed'.

How do you pronounce kubeadm (Kubernetes cluster bootstrap tool)?
Kubeadm is pronounced 'kyoob-ADM' (/kjuːbˈædm/). It combines 'kube' (Kubernetes) + 'adm' (admin/administration). The tool bootstraps Kubernetes clusters. Stress falls on the second part: kyoob-ADM. The 'adm' is spoken as three letters A-D-M or as the abbreviation 'adm'.

How do you pronounce containerd (container runtime)?
Containerd is pronounced 'kun-TAYN-erd' (/kənˈteɪnərd/), like 'container' + 'd'. The trailing 'd' is the Unix convention for a daemon (background service). It is the industry-standard container runtime used by Kubernetes. Say it as one word: kun-TAYN-erd.

How do you pronounce kubelet (Kubernetes node agent)?
Kubelet is pronounced 'KYOO-buh-let' (/ˈkjuːbəlɛt/). It is 'kube' + the diminutive suffix '-let' (meaning small), making it the small agent that runs on each Kubernetes node. Stress on the first syllable: KYOO-buh-let, three syllables total.

How do you pronounce cgroups (Linux control groups)?
Cgroups is pronounced 'SEE-groups' (/ˈsiːɡruːps/) as a single word. It stands for 'control groups', a Linux kernel feature that limits and isolates resource usage (CPU, memory, I/O) of process groups. Kubernetes uses cgroups to enforce container resource limits. Always one word: SEE-groups.
