PowerShell

For PowerShell (pwsh) add the following lines to your profile ($PROFILE):

C:\Users\yourusername\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

# Set aliases
Set-Alias -Name kubectl -Value kubecolor
Set-Alias -Name k -Value kubectl

Completions

Completion can be easily borrowed from the kubectl command by adding this to your profile:

C:\Users\yourusername\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

# Reuse the kubectl completion on kubecolor and the aliases
Register-ArgumentCompleter -CommandName 'k','kubectl','kubecolor' -ScriptBlock $__kubectlCompleterBlock

As a prerequisite, you need kubectl completions installed. This can be achieved by adding this to your profile:

C:\Users\yourusername\Documents\PowerShell\Microsoft.PowerShell_profile.ps1

# Completion for kubectl
# This needs to be added before Register-ArgumentCompleter
if (Get-Command kubectl -ErrorAction SilentlyContinue) {
  # This also registers the $__kubectlCompleterBlock variable
  kubectl completion powershell | Out-String | Invoke-Expression
}
