It’s going in my .config/nvim/lua/config/autocmds.lua

I use lazyvim

I created an auto command for this

-- Ansible file pattern
  vim.api.nvim_create_autocmd({ "BufRead", "BufNewFile", "BufEnter" }, {
    group = vim.api.nvim_create_augroup("Ansible", { clear = true }),
    pattern = {
      "*/roles/*/*/*.yaml",
      "*/roles/*/*/.yml",
      "main.yml",
      "main.yaml",
      "Debian*.yaml",
      "Debian*.yml",
      "*/ansible-devbox/*.yaml",
      "*/ansible-devbox/*.yml",
      "group_vars/*.yml",
      "group_vars/*.yaml",
      "files/*.yaml",
      "files/*.yml",
      "environments/*.yaml",
      "environments/*.yml,",
    },
    callback = function()
      vim.opt.filetype = "yaml.ansible"
    end,
  }),
