Part of the problem is that these are duplicated between the different commands. I'm planning to consolidate these further.

|
|
Edit a resource from the default editor.
|
|
|
|
The edit command allows you to directly edit any API resource you can retrieve via the
|
|
command line tools. It will open the editor defined by your KUBE_EDITOR, or EDITOR
|
|
environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows.
|
|
You can edit multiple objects, although changes are applied one at a time. The command
|
|
accepts filenames as well as command line arguments, although the files you point to must
|
|
be previously saved versions of resources.
|
|
|
|
Editing is done with the API version used to fetch the resource.
|
|
To edit using a specific API version, fully-qualify the resource, version, and group.
|
|
|
|
The default format is YAML. To edit in JSON, specify "-o json".
|
|
|
|
The flag --windows-line-endings can be used to force Windows line endings,
|
|
otherwise the default for your operating system will be used.
|
|
|
|
In the event an error occurs while updating, a temporary file will be created on disk
|
|
that contains your unapplied changes. The most common error when updating a resource
|
|
is another editor changing the resource on the server. When this occurs, you will have
|
|
to apply your changes to the newer version of the resource, or update your temporary
|
|
saved copy to include the latest resource version.`))
