* Correcting name of concept 'Container Enviorment Variables'
This page discusses the container environment and container environment variables are part of it. So removing a 'variable' word to make it more correct.
* Correcting references
Correcting references
* Correcting reference links
Correcting reference links
* Expand list of places Kubernetes can run
As well as GKE, there are AKS, EKS, and more.
* Add page description
* Link to blog post about Borg
The blog post has (a better) link to Google's paper about Borg. Because
of the historical relevance of that paper and that blog article to the
history of Kubernetes, I think it's OK to link there.
Linking to the blog article provides a less academic introduction to the
history of Kubernetes, with the option to click through and learn things
in detail.
* Remove mentions of unsupported Kubernetes versions
No need to mention supported-since-this-version details for Kubernetes
releases that are now out of support.
* Warn about disabling preemption
* Tweak wording
* Add What's next section
* Tweak Pod priority troubleshooting advice
Reshape the advice about pod priority troubleshooting to explain
user-induced issues (and define expected behavior). If the reader
detects behavior that does not match the documentation, they have
observed a bug and can report that via the usual routes.
* Rewords notes on Pod priority vs. QoS
* Move warning into page body
Issue #17556
Problem:
Below Lines are incorrect
If you specify multiple nodeSelectorTerms associated with nodeAffinity types, then the pod can be scheduled onto a node if one of the nodeSelectorTerms is satisfied.
If you specify multiple matchExpressions associated with nodeSelectorTerms, then the pod can be scheduled onto a node only if all matchExpressions can be satisfied.
Proposed Solution:
They need to be corrected to below
If you specify multiple nodeSelectorTerms associated with nodeAffinity types, then the pod can be scheduled onto a node only if all nodeSelectorTerms can be satisfied.
If you specify multiple matchExpressions associated with nodeSelectorTerms, then the pod can be scheduled onto a node if one of the matchExpressions is satisfied.
* Update what-is-kubernetes.md
The sub heading felt awkward as it was asking a question, but there was no question mark. As question marks in headings are not ideal in technical documentation anyway, I thought swapping the word order slightly made it sounds _slightly_ better.
* Update content/en/docs/concepts/overview/what-is-kubernetes.md

* Reword API Server aggregation
* Document custom resources ahead of APIService
CustomResourceDefinition is the newer, shinier and often more
appropriate resource to help with cases where APIService was not a good
fit. Switch order to mention the custom resources page first, which
introduces both APIService and CustomResourceDefinition.
* Add whats next section to PersistentVolume page
Add whats next section to PersistentVolume page
* Adding references to PersistentVolume page
Adding references to PersistentVolume page
* Use feature state for non-preempting PriorityClasses
* PreemptionPolicy requires NonPreemptingPriority feature gate
* Remove alpha qualifier from section title and decrease example heading level
* Use singular of PriorityClass in the heading
* Note CronJob timezone comes from system timezone
The timezone for the kube-controller-manager (or if that's broken apart,
the cronjob controller) determines when CronJobs are scheduled.
This reverts commit bad124b857.
* Expand details about CronJob timezone
