openelb VS cobra

My project was "CNCF - OpenELB: Provide the OpenELB Web UI for managing EIP and IP pool". I had to develop a web console for creating and managing the OpenELB resources. Now you might be wondering what is OpenELB. Well, OpenELB is an open-source load balancer implementation designed for exposing the LoadBalancer type of Kubernetes services in bare metal, edge, and virtualization environments. You can learn more about it here https://openelb.io/. Here's the project URL https://github.com/openelb/openelb. It is a sandbox project in CNCF.

We can use the flag with --date or -date, Go already does the automatic check. We can make our entire boilerplate with this approach, but let's make it a little easier and use the Cobra CLI package.

In this tutorial, we'll walk through the process of creating a simple command-line tool similar to curl using Go and Cobra, a CLI library for Go.

I use https://github.com/spf13/cobra religiously for this kind of thing - it handles all the annoying corner cases of parsing flags, and also has an intuitive notion of subcommands (with basic usage/help text generated) for picking which task you want to run with positional arguments.

We recently chose cobra[1] to create a cli application. It comes with so many best practices already packaged like autocompletions, help texts etc. etc.

I looked at the docs: https://cobra.dev/ ... and there are only examples on how to add new flags.

For installing Cobra-CLI you can go to Cobraor run go install github.com/spf13/cobra-cli@latest in the terminal.

In my build phase, I compile the source to create a k3sup binary and I also run the binary to generate shell script completions. Give kudos to this functionality which comes from spf13/cobra Go library for CLIs.

NWA is a command-line tool built on cobra. Here's an overview of NWA's commands:
