So I know kubernetes.io is allowed for undertaking the CKA exam.
However, one of the tasks included in the curriculum is to install a basic kubernetes cluster with Kubeadm. But you would need to install docker engines and containerd, instructions for both of them are external links to lead you to their respective sites.
Now I am not going to memorise all of this, so please can anyone tell me whether we can use the official documentation for containerd and docker engines?
Or will I not need to know how to set up docker and containerd in the first place?
Don’t worry. You will not have to set up all of that in the exam. Very unlikely you will need to install anything. You could well be asked a cluster upgrade question though,

Damn that’s a relief. It does say explicitly you need to create cluster and is covered in several courses though.
If you do, it would only be the latter stages, e.g the kubeadm init and node joins.
You would not have to install container runtimes etc.
The average time allocation per question in a CKA is about 6 minutes. Not possible to do a ground-up install in this amount of time - even for me
