[chef] Re: Re: Overriding default attributes

[Leonard Messier < >]

Thanks Tom,

Changing it the way you did removed this error. However, another one appeared.

When trying to create the sudoers.d directory, chef complained about insufficient permissions. Reading further in the sudo's cookbook readme, I found a mention of the « sysadmin » group not beeing created by the sudo cookbook itself. 

I thought that I would install the users community cookbook, that essentially creates the sysadmin group when the sysadmins recipe is included. I created a users in data_bags/users, belonging to a sysadmin group. I get the following error :

My recipe set is on this git repo, on the dev branch

Thanks in advance

The reason your bit is failing is that the precedence for attributes specified via the -j flag is normal. If you get rid of the “override_attributes” level of your hash and bring authorization to the top level it should work.

Ohai there,

I'm quite new to chef, sorry for the noobish question. Here is my problem :

I had a set of recipes for my developpment machine that I used to run with sudo like this : 

sudo chef-solo -c config/solo.rb -j config/system.json

At some point, I decided to rework it from the ground up with chefspec testing which lead me to understand that using sudo was a very bad idea.

I included the community sudo cookbook in my kitchen, but I don't have a clue on how to override the default attributes being set on it. This is the last content of my system.json file.

{

  "run_list": [ "system::default" ],

  "override_attributes": {

    "authorization": {

      "sudo": {

        "prefix": "/etc",

        "groups": [ "virtualeo" ],

        "users":  [ "virtualeo" ],

        "passwordless": "true",

        "include_sudoers_d": "true"

      }

    }

  }

}

Launching the command in a ubuntu 13.04 that I virtualized for testing, I get the following result :

What I understand from this stacktrace is that  « node['authorization']['sudo']['prefix'] » causes the error. 

I guess the solution is pretty straightforward but I'm stuck for now !

Thanks in advance
