chef recipe compile error as "undefined method 'cwd' for cookbook"

I have a chef recipe to iterate multi module from json array.

Here i have defined the cwd from the json node attribute, but it is getting failed with the chef recipe compile error as "undefined method 'cwd' for cookbook".

Becuase in the devops_dir/scripts we are having the shell script to call and execute for each iteration of module in the json Array(modules).

Please correct me.

role name: role.json

{
    "name": "role_multi_module",
    "default_attributes": {
        "employees": [{
                "name": "Ram",
                "email": "[email protected]",
                "age": 23
            },
            {
                "name": "Shyam",
                "email": "[email protected]",
                "age": 28
            }
        ],
        "cloud": {
            "global": false
        },
        "devops_dir": "/home/ec2-user/chef-repo/cookbooks/hello-chef/recipes",
        "user": "ec2-user",
        "group": "ec2-user"
    },
    "override_attributes": {},
    "json_class": "Chef::Role",
    "description": "This is just a test role, no big deal.",
    "chef_type": "role",
    "run_list": ["recipe[multi-module]"]
}

Chef recipe: multi-module.rb

node['employees'].each do |employee|
  execute "test-multi-#{employee['name']}" do
    cwd "#{node['devops_dir']}/scripts/"
    user node['user']
    group node['group']
    command "bash shell.sh #{employee['name']} #{employee['email']}"
  end
end

shell.sh and directory (/home/ec2-user/chef-repo/cookbooks/hello-chef/recipes/scripts)

[ec2-user@ip-172-31-95-251 scripts]$ pwd
/home/ec2-user/chef-repo/cookbooks/hello-chef/recipes/scripts
[ec2-user@ip-172-31-95-251 scripts]$ ll
total 4
-rwxrwxrwx 1 ec2-user ec2-user 61 Sep  6 09:18 shell.sh
[ec2-user@ip-172-31-95-251 scripts]$ cat shell.sh
name=$1
email=$2
echo "Print Name: $name and Email: $email"

devops_dir is existed but the shell script is not running from the above recipe logic. I have a doubt will the node variables like devops_url execute inside the modules (arrays).?

This error is because cwd is a property of execute resource, and it should be within that block. Same is the case with user and group.

Also, when we specify attributes/variables from role, we don't need to specify node['role'] prefix. We can directly access node['devops_dir'], etc.

So your code modified as below should work fine:

node['employees'].each do |employee|
  execute "test-multi-#{employee['name']}" do
    command "bash python.sh #{employee['name']} #{employee['email']}"
    cwd "#{node['devops_dir']}/scripts"
    user node['user']
    group node['group']
  end
end
