CKA, CKAD, CKS - Jan 03 2022

CKA & CKAD Environment

• Each task on this exam must be completed on a designated cluster/configuration context.

• There are six clusters (CKA) / four clusters (CKAD) that comprise the exam environment, made up of varying numbers of containers, as follows:

		CKA Clusters
Cluster	Members	CNI	Description
k8s	1 master, 2 worker	flannel	k8s cluster
hk8s	1 master, 2 worker	calico	k8s cluster
bk8s	1 master, 1 worker	flannel	k8s cluster
wk8s	1 master, 2 worker	flannel	k8s cluster
ek8s	1 master, 2 worker	flannel	k8s cluster
ik8s	1 master, 1 base node	loopback	k8s cluster − missing worker node

		CKAD Clusters

Common Enviroment

For your convenience, all environments, in other words, the base system and the cluster nodes, have the following additional command-line tools pre-installed and pre-configured:

• kubectl with kalias and Bash autocompletion << wow good

• jq for YAML/JSON processing

• tmux for terminal multiplexing

• curl and wget for testing web services

• man and man pages for further documentation
