Wrong number of arguments (2 for 0..1)


I come with another issue.
I want to create a file from template using instances variable. The attribute file looks like:

default['super']['a']['destination']		= 'a'
default['super']['a']['autorestart'] 		= 'true'
default['super']['a']['logfile_maxbytes']	= '5MB'
default['super']['a']['logfile_backups']	= 10

default['super']['b']['destination']		= 'b'
default['super']['b']['autorestart'] 		= 'true'
default['super']['b']['logfile_maxbytes']	= '6MB'
default['super']['b']['logfile_backups']	= 12

default['super']['c']['destination']		= 'c'
default['super']['c']['autorestart'] 		= 'true'
default['super']['c']['logfile_maxbytes']	= '15MB'
default['super']['c']['logfile_backups']	= 100

And the template defining in the recipe is this:

template 'super.conf' do
	path "/etc/super.conf"
	source "super.conf.erb"
	owner 'user'
	group 'user'
	mode "0644",
		:instances => node['super']

The error I get is this:

wrong number of arguments (2 for 0..1)

Any thoughts, please?

Thank you,

Was just a typo.

I shouldn’t have a comma in the recipe after mode… It was obvious.

Sorry to have posted it before having a better look at the code.



Looks like there is a comma at the end of the mode method.

Mode is expecting a single parameter but you are passing two parameters. Remove comma as below

 39:  template 'super.conf' do
 40:    path "/etc/super.conf"
 41:    source "super.conf.erb"
 42:    owner 'user'
 43:    group 'user'
 44    mode "0644"
 45:    variables(
 46:            :instances => node['super']
 47:    )
 48:  end

What is happening when Chef compiles a cookbook is that the resource settings are evaluated, when you see

mode "0644"

You are calling a method called mode with the parameter argument “0644”

Thank you,
