@halfcrazy these are great updates, thank you for taking the time to do this PR! That said, there are some that will be only ephemeral changes as the pages that you're making changes are from generated documentation. Pages where the URI includes generated or imported are generally ones that have come from an automatic process - usually driven by code elsewhere. All this to let you know that the next time those pages are generated and updated (usually on the quarterly release, but sometimes more frequently) the spelling changes you're proposing there will revert.

There's some docs on how we generate content for these pages:

• https://kubernetes.io/docs/home/contribute/generated-reference/kubernetes-components/
• https://kubernetes.io/docs/home/contribute/generated-reference/kubectl/
• https://kubernetes.io/docs/home/contribute/generated-reference/kubernetes-api/
• https://kubernetes.io/docs/home/contribute/generated-reference/federation-api/

But the long and short is that changes to typo's in there usually need to be hunted down and resolved in the source code from where the documentation is generated.
