completion

This depends on the bash-completion binary.  Example installation instructions:
OS X:
	$ brew install bash-completion
	$ source $(brew --prefix)/etc/bash_completion
	$ minikube completion bash > ~/.minikube-completion  # for bash users
	$ minikube completion zsh > ~/.minikube-completion  # for zsh users
	$ source ~/.minikube-completion
	$ minikube completion fish > ~/.config/fish/completions/minikube.fish # for fish users
Ubuntu:
	$ apt-get install bash-completion
	$ source /etc/bash_completion
	$ source <(minikube completion bash) # for bash users
	$ source <(minikube completion zsh) # for zsh users
	$ minikube completion fish > ~/.config/fish/completions/minikube.fish # for fish users

Additionally, you may want to output the completion to a file and source in your .bashrc

Windows:
	## Save completion code to a script and execute in the profile
	PS> minikube completion powershell > $HOME\.minikube-completion.ps1
	PS> Add-Content $PROFILE '. $HOME\.minikube-completion.ps1'

	## Execute completion code in the profile
	PS> Add-Content $PROFILE 'if (Get-Command minikube -ErrorAction SilentlyContinue) {
	        minikube completion powershell | Out-String | Invoke-Expression
	    }'

Note for zsh users: [1] zsh completions are only supported in versions of zsh >= 5.2
Note for fish users: [2] please refer to this docs for more details https://fishshell.com/docs/current/#tab-completion
