[Feature Request] Add support for CRDs

[helayoty]

As a user, I would like to be able to import a CRD and create CR based on it.

@same7ammar I'd like to take on this feature request. I've looked through the project and have a good understanding of the approach needed to add support for CRDs.

Please assign this issue to me when you get a chance. I'm looking forward to contributing.

Hello @Chandru03 ,

Thank you for response and happy to see your contribution.

I will assign it to you and please feel free to share with us the expected results by adding this to project.

Are you going to allow the users to generate CRD or allow them to extract the custom resource from uploading CRD Yaml files . Just to limit the scope of this PR.

Hello @same7ammar

Thank you for assigning this! I'm excited to contribute.

To scope this initial PR, my plan focuses on:

1. CRD YAML Import: Allowing users to paste or upload CRD YAML to be parsed.
2. Basic CR Form Generation: Creating a simple form for users to define Custom Resource (CR) fields based on the imported CRD's schema. This will focus on core apiVersion, kind, metadata.name, and top-level spec properties for the first iteration.
3. Real-time CR YAML Generation: Displaying the Custom Resource (CR) YAML as the user inputs data.

Expected Results (Initial PR):

• A new UI section/tab for Custom Resources.
• CRD YAML input (text area/file upload).
• Parsing of CRD YAML to understand its schema.
• Basic interactive form for CR input.
• Real-time generation and display of CR YAML.

This establishes the fundamental CRD import and CR generation pipeline. Advanced dynamic form generation and validation can follow in subsequent PRs.

Please let me know if this scope aligns with your expectations.

Thanks again!

Hello @Chandru03 ,

Thank you for provided details You can start working on it

We need to add Menu item in the sidebar menu called Advanced .

You might follow the below (Optional or suggest more simple options is welcomed ).

2. user can import the file as below or something different .

3. once upload you can show the user basic CRD details like below .

4. Ask the user to add basic required details in form to something different .

5. Generate the CR you can think about it , it should be easy and accessible UI .

@helayoty Do you have any thoughts on this feature . You feedback is very appreciated .

Example CRD

@same7ammar I’ve created a CRD format for YAML, but I’m not a Kubernetes expert and need some validation. I’m only familiar with the basics, so I’d appreciate it if you could validate this or suggest any improvements.
