Quite some resources have been moved out of the `extensions` API group
since 1.18; the `apps/v1beta1` and `apps/v1beta2` group versions are
also dropped. This PR updates the pages which still reference such API
groups or group versions.
The [Poseidon
project](https://github.com/kubernetes-sigs/poseidon/commits/master)
is virtually dead:
- No PRs coming in since Dec 2019
- PRs related to code changes date back to April 2019.
By removing this page, we can save folks' effort on localizing the
content, i.e. #22265.
The last sentence of the third paragraph was worded in an unreadable way.
Before: Claims can request specific size and access modes (e.g., they can be mounted once read/write or many times read-only).
Replaced with technical terms and hyperlinked to Access Modes section on the same page.
Where an existing Concept section has an index and the first page is
“Overview of X”, move the content of that overview into the index page
itself.
Also, configure redirects accordingly.
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.
The existing ConfigMap concept incorrectly states that you must use
different ConfigMap objects if you want to configure both environment
variables and file-like configuration items at the same time.
Reword to give the correct advice.
Add quotation marks around the value of the key "player_initial_lives" in configuration file of the ConfigMap called "game-demo". Otherwise, kubectl version 1.18 gives the following error with the command "kubectl apply -f game-demo-configMap.yaml"
Error from server (BadRequest): error when creating "game-demo-configMap.yaml": ConfigMap in version "v1" cannot be handled as a ConfigMap: v1.ConfigMap.Data: ReadString: expects " or n, but found 3, error found in #10 byte of ...|l_lives":3,"ui_prope|..., bigger context ...|player.maximum-lives=5\n","player_initial_lives":3,"ui_properties_file_name":"user-interface.propert|...
From context and general understanding, it looks like this was intended to be "most Kubernetes users will *not* need to
install extensions and fewer will need to author new ones."
