The HTML5 named character reference such as '>', '<' should be terminated
with semicolon character. This commit fixes the missing termination character
with the kubernetes-basics tutorials.
kubectl run starting from 1.18 is creating only Pods and there is no option to
create any other resource. Users should be using kubectl create
commands instead. This update the documentation in all those places
where kubectl create should be used instead or changes description to
reflect the situation.
