One improvement to kube_ctx_namespace

[ildar-shaimordanov]

Hi all!

Looking for new ideas I found your project. It gave me some ones and I'd like to share my visions with you. Hope it will help you further.

fubectl/fubectl.source

Lines 80 to 85 in 3950b1e

	# [kube_ctx_namespace] get current namespace
	function kube_ctx_namespace() {
	local default_ns="$(kubectl config view --minify|grep namespace: |sed 's/namespace: //g'|tr -d ' ')"
	default_ns="${default_ns:-default}"
	echo "$default_ns"
	}

I think the snippet above can be improved a little bit in the way as below. It requires kubectl itself and its jsonpath features that have already been embedded.

kubectl config view --minify \
-o jsonpath="{range .contexts[*].context}{@.user}{\"@\"}{@.cluster}{\":\"}{@.namespace}{\"\n\"}"

It displays the current context in the form similar to the unix prompt like user@cluster:namespace. It's constructed to be used directly or as an alias. You can take it as is or modify on your wants or drop as a bad idea for your project :).
