As per the issue #35432, hostname command is no longer available as mysql:5.7 is based on oracle.
For the command on line 27 to work, it is sufficient to use the $HOSTNAME variable which is set in the container,
for it to work effectively.
k8s.gcr.io is deprecated in favor of registry.k8s.io. The kubernetes
codebase have been updated with the new endpoint.

The stateless application tutorial is littered with unsuitable terminology. This update switches the database technology to a database that has already updated their own terminology as well as removes the terminology from the tutorial itself.
The advanced logging tutorial followup is set to Draft as it will take a larger effort to convert that, and I'm not convinced its even in a working state right now.
A followup PR to the examples repo to be referenced here will be made.

Clarify that `REMOTE_PORT` is interpreted as identifying a _Service_ port when provided `TYPE` is `service`.
Also, highlight support for specifying a named port as `REMOTE_PORT`.
- Ignore 'xtrabackup_slave_info' if it is an empty file.
- Remove the tailing semicolon in 'xtrabackup_slave_info'.
- Stop script when 'CHANGE MASTER' is failed, then rename 'change_master_to.sql.in' only when changing master is successful.
In given manifest, podManagementPolicy is set as Parallel, but in later section of page, the console logs of "kubectl get pods -w -l app=zk" command displays ordered behavior, which is not the actual result in case of Parallel option.

Resolution :
Either change the value of podManagementPolicy option to OrderedReady or remove that option, so that StatefulSet will take it's default behavior.
This is the last PR for moving the YAML/JSON sample files. There still
need some follow up PRs to:
- rename the `codenew` shortcode to `code`.
- move the examples_test.go to where it really belongs.
This PR deals with YAML files referenced by the following two topics:
- concepts:object management
- concepts:service networking
When scanning references to the YAML files to be moved, some trivial
editings were applied to the markdown files. None of this editing should
break the build or ruin the doc otherwise.
* Consolidate YAML files [part-8]
This PR exacts the YAML files referenced from the following subdirs:
- docs/concepts/workloads
- docs/concepts/configuration
- docs/concepts/policy
The following problems are fixed:
- docs/concepts/workloads/controllers/ doesnt have a 'cronjob.yaml for
test
- the exactly same `pod.yaml` was used in both the task/config-pod-container
topic and the concepts/configuration topics.
* Update examples_test.go
* Add missing yaml file.
