Chef-client Cookbook on Windows: Cache location

dave12345 · February 7, 2020, 11:48am

Hi,

Re: chef-client-15.5.17-1-x64 and chef-client supermarket cookbook 11.4.0 on Windows Server 2012 x64

I'm using the the chef-client cookbook and its "config" recipe to template the client.rb file.

I notice that C:/chef/cache attribute that was there has been removed in the client.rb file post change and the scheduled task command options doesn't reference it either ...

However when a chef run starts it knows where the cache is. I'd like to understand how this works as investigating if moving cache off the C drive is valid.

many thanks and have a great weekend.

David

The cache is simply another parameter (cache_path) you can pass in. You can add it to client.rb or as a CLI parameter. This defaults to C:/chef/cache on windows. If you're curious about the details you can look at this:

github.com

chef/chef/blob/5a9f64b83e4605ee4d23190a3afcf08b000e3da1/chef-config/lib/chef-config/config.rb#L324


default :formatter, "null"


# The number of times the client should retry when registering with the server
default :client_registration_retries, 5


# An array of paths to search for knife exec scripts if they aren't in the current directory
default :script_path, []


# The root of all caches (checksums, cache and backup).  If local mode is on,
# this is under the user's home directory.
default(:cache_path) do
  if local_mode
    PathHelper.join(config_dir, "local-mode-cache")
  else
    primary_cache_root = var_root_dir
    primary_cache_path = var_chef_dir
    # Use /var/chef as the cache path only if that folder exists and we can read and write
    # into it, or /var exists and we can read and write into it (we'll create /var/chef later).
    # Otherwise, we'll create .chef under the user's home directory and use that as
    # the cache path.
    unless path_accessible?(primary_cache_path) || path_accessible?(primary_cache_root)

The chef-client cookbook appears to handle it via this attribute: default['chef_client']['file_cache_path'] = "#{node['chef_client']['conf_dir']}/cache"
