kubectl ns plugin

Simple Plugin to display/change the current kube namespace with support for substring matching.

Build from source

go version >= 1.13 with modules support enabled is required to build the plugin from source.

export GO111MODULES=on # optional if checked out outside of $GOPATH
go build

Installation

Pre-compiled statically linked binaries are available on the releases page.

Binary must be placed anywhere in $PATH named kubectl-ns with execute permissions. For further information, see the offical documentation on plugins here.

Compatibility

Known to work on Windows and Linux. Requires kubectl >= 1.12 (tested with versions >1.12). Supports the oidc, gcp and azure auth provider for authentication against the k8s api server.

Examples

For all the examples, assume your cluster has the following namespaces:

default
kube-system
kube-public
ingress-nginx
foo
bar
baz

display namespaces

Current namespace is displayed in a different color and last.

$ kubectl ns
default
kube-system
kube-public
ingress-nginx
foo
bar
baz

Substring matching can be used to display namespaces. For example if you are searching for a kube- namespace simply type:

$ kubectl ns kube-
kube-system
kube-public

change current namespace

You can switch the namespace by providing an exact name:

$ kubectl ns foo
namespace set to "foo"

But it's also possible to switch to the ingress-nginx namespace by typing a substring (as long as it is a unique name), for example:

$ kubectl ns ingress
namespace set to "ingress-nginx"
