Kubectl: Enhance kubectl create (Add useful flags from kubectl run e.g. replicas, labels, requests, limits, env, port etc.)

[armujahid]

kubectl create is currently too limited. kubectl run gave a-lot flexibility in creating deployments and jobs via command-line.
We can do very little with kubectl create without editing yaml file. In my opinion it was a very bad idea to remove generators in kubectl run without providing similar functionality in kubectl create.

What would you like to be added:
Add the functionality lost as a result of generators removal from kubectl run. We should be able to add labels, replicas, requests, limits or any other functionality that is supported by kubectl run.
Flags required:

• replicas
• labels
• requests
• limits
• env
• port
• serviceaccount

Why is this needed:
The current kubectl create is way too limited!! It really hinders what can be done via command-line.

@armujahid there's a discussion that needs to be had about enhancing kubectl create/run and their intended goals. I've added it to the agenda for our next SIG-CLI meeting and it would be great to have you join us.

Next meeting is August 12th at 9:00 AM Pacific Time.

@armujahid are you ok closing this after the SIG-CLI discussion?

As a note of historical reference it was discussed that create/run commands are not going to be expanded to push folks to use other tools and best practices. We will be spinning up a new SIG subproject to attempt to tackle a kubectl generate.

Will link to recording when it's uploaded.

Sure. I would love to contribute to kubectl generate
