ftplugin Customizations

You can expand kubectl.nvim by adding your own ftplugins for the k8s_* filetypes.
In this example, I add to my config's location ~/.config/nvim/ftplugin/k8s_fallback.lua
It defines the <Plug>(kubectl.select) keymap to open the application's page on our browser using the server's ingress host.
Warning
This might not work for everyone, the ingress may not return a host or your configuration is a bit different. Anyway, it gives a basic idea.
local commands = require 'kubectl.actions.commands'
local tables = require 'kubectl.utils.tables'
vim.schedule(function()
vim.api.nvim_buf_set_keymap(0, 'n', '<Plug>(kubectl.select)', '', {
noremap = true,
silent = true,
desc = 'Go to application',
callback = function()
local _, buf_name = pcall(vim.api.nvim_buf_get_var, 0, 'buf_name')
local lower_buf_name = string.lower(buf_name)
if lower_buf_name == 'applications' or lower_buf_name == 'applications.argoproj.io' then
local name = tables.getCurrentSelection(2)
if not name then
return
end
local ingress_host = commands.shell_command(
'kubectl',
{ 'get', 'ingress', '-n', 'argocd', '-l', 'app.kubernetes.io/component=server', '-o', 'jsonpath={.items[].spec.rules[].host}' }
)
local final_host = string.format('https://%s/applications/argocd/%s', ingress_host, name)
vim.notify('Opening ' .. final_host)
vim.ui.open(final_host)
end
end,
})
end)
