Processes kubectl outputs to enable vim-like navigation in a buffer for your cluster.
Navigate your cluster in a buffer, using hierarchy where possible (backspace for up, enter for down) e.g. root -> deplyoment -> pod -> container
Colored output and smart highlighting
Floating windows for contextual stuff such as logs, description, containers..
Completion
Run custom commands e.g :Kubectl get endpoints
Change context using cmd :Kubectx context-name or the context view
Exec into containers
In the pod view, select a pod by pressing<cr> and then again <cr> on the container you want to exec into
Sort by headers
By moving the cursor to anywhere in a column and pressinggs
Tail logs
Diff view: :Kubectl diff (path)
Port forward
Aliases (fallback view)
A fallback view that directs custom resources and has basic functionality such desc, edit, del
Overview
- kubectl
- curl
- neovim >= 0.10
Install the plugin with your preferred package manager:
return {
{
"ramilito/kubectl.nvim",
config = function()
require("kubectl").setup()
end,
},
}We expose open, close and toggle to bind against:
vim.keymap.set("n", "<leader>k", '<cmd>lua require("kubectl").toggle()<cr>', { noremap = true, silent = true })You can override the plugin's keymaps using the <Plug> mappings:

The setup function only adds ~1ms to startup. We use kubectl proxy and curl to reduce latency.
We leverage the Kubernetes Informer to efficiently monitor resource updates.
By using the resourceVersion, we avoid fetching all resources in each loop.
Instead, the Informer provides only the changes, significantly reducing overhead and improving performance.
As we advance to v1.0.0, our primary goal is to maintain the stability of the
plugin and minimize any breaking changes. We are committed to providing a
reliable and consistent user experience.
This plugins main purpose is to browse the kubernetes state using vim like navigation and keys, similar to oil.nvim for file browsing.
