Chef::Exceptions::FileTypeMismatch


#1

Why will this not work? I am trying to use a override for a cookbook
file. Yet I get the below error

In Attributes:

default[‘environment’][‘chef’][‘validation_key’] = nil
default[‘environment’][‘chef’][‘client_key’] = nil

In recipe:

directory “/home/ubuntu/.chef” do
owner "ubuntu"
group "ubuntu"
mode "0755"
recursive true
action :create
end

validation_key = node[‘environment’][‘chef’][‘validation_key’]
client_key = node[‘environment’][‘chef’][‘client_key’]

cookbook_file “/home/ubuntu/.chef/#{validation_key}” do
source "#{validation_key}"
mode 00644
end
cookbook_file “/home/ubuntu/.chef/#{client_key}” do
source "#{client_key}"
mode 00644
end

In role with override attribute

“override_attributes”: {
“environment”:{“chef”:{“validation_key”:“t1”}},
“environment”:{“chef”:{“client_key”:“t2”}}
}

Hi David,

The reason you’re seeing that “File Type Mismatch” exception is that your
override isn’t working, causing your cookbook_file resource and your
directory resource to clash. (Sorry. You probably knew that.)

I think you have some malformed JSON. Run it through an online validator
to be sure. (I went in circles for days with RunDeck ACLs and the culprit
turned out to be malformed YAML. Live and learn!)

Change:
“override_attributes”: {
“environment”:{“chef”:{“validation_key”:“t1”}},
“environment”:{“chef”:{“client_key”:“t2”}}

<— here you clobber [:environment][:chef] so that it no longer has

[:validation_key] in it!
}

To:

“override_attributes”: {
“environment”: {
“chef”: {
“validation_key”: “t1”,
“client_key”: “t2”
}
}
}

OK, now that your recipe will hopefully work the way you want it, I’d like
you to think about something: You’re relying on the consumer of this
cookbook (“Future You,” “The Rest of Your Team,” “The Internet,” whoever)
to override node attributes, or the recipe won’t work.

I suggest modifying your recipe to provide a sane default behavior for
those node attributes and to have it check to see if the local variables
are assigned nil values … and either fix it so that things work or tell
the user they’re going to have a bad time and why. Otherwise, someone
might tear their hair out over this some day…
