Yaml snippets not showing up

[RAPSNX]

Coq comes with default snippets if coq.arifacts is installed, this is working out of the box for files like go, python, typescript and javascript and many more.

Execept for yamls, i cant access any snippets in yaml files. I like to have all the kubernetes snippets available in every *.yaml file. I tried to configure the yamlls language server to map all yamls to the filetype kubernetes, but it dosent work.

My lsp config looks like this:

local lspconfig = require('lspconfig')

-- coq autocompletion
-- set xdg dir for coqDeps since nix is readonly
vim.g.coq_settings = {
  xdg = true,
  auto_start = 'shut-up',
}

local coq = require "coq"

local servers = {
  gopls = {},
  rnix = {},
  terraformls = {},
  rust_analyzer = {},
  yamlls = {
    filetypes = {"yaml", "kubernetes"},
  },
}
for server, config in pairs(servers) do
  lspconfig[server].setup(coq.lsp_ensure_capabilities(
    vim.tbl_deep_extend("force", {
      on_attach = on_attach,
      capabilities = capabilities,
      flags = {debounce_text_changes = 150},
      filetypes = config.filetypes,
    }, {}))
  )
  local cfg = lspconfig[server]
    if not (cfg and cfg.cmd and vim.fn.executable(cfg.cmd[1]) == 1) then
      print(server .. ": cmd not found: " .. vim.inspect(cfg.cmd))
    end
end
