How to put every array element in double quotes

Question

Within Chef, the attribute looks as below:

default['cluster']['ipaddress'] = ["10.211.130.108", "10.211.242.203"]

Within Chef recipe, I have put every array element in double quotes, using map:

json_nodes = node['consul']['cluster']['ipaddress'].map { |s| "#{s.to_s}:8300" }

bash 'configuring file.json' do
  code <<-EOH
    echo #{json_nodes} > "/home/user1/file.json"
  EOH
end

I get the following output within the file /home/user1/file.json:

[10.211.130.108:8300, 10.211.242.203:8300]

The output should have double quotes as follows:

["10.211.130.108:8300", "10.211.242.203:8300"]

The output is really as you described, not "10.211.130.108:8300,10.211.242.203:8300"? — StephenKing

Have a look at the file resource. Also this question here on SO. — StephenKing

That you want to put that into a file via chef's bash resource is kind of the most important information! — StephenKing

How about:

json_nodes = node['cluster']['ipaddress'].map { |s| "#{s.to_s}:8300" }

I don't have your data but here is an example from my console:

[3] pry(main)> arr = [1,2,3,4,5]
=> [1, 2, 3, 4, 5]
[4] pry(main)> arr.map { |s| "#{s.to_s}:3000" }
=> ["1:3000", "2:3000", "3:3000", "4:3000", "5:3000"]

Note that when I put the .join on the end, it concats them all in a single string.

[8] pry(main)> arr.map { |s| "#{s.to_s}:3000" }.join(',')
=> "1:3000,2:3000,3:3000,4:3000,5:3000"

I don't see the double quotes. The output is still [10.211.130.108:8300,10.211.242.203:8300]

Are you still doing the .join(',') on the end? If so, that's going to concat all the elements into a comma delmited string. If you want the elements of the array to be double quoted, my answer should work.

It is not working. can you help with the answer that I have posted recently

I am getting this output without putting .join(',') [10.211.130.108:8300, 10.211.242.203:8300]

andrunix Over a year ago

I added some example code straight from my console. Hope it helps.

Things become a lot easier, when you use Chef in the way it is made for (and don't call bash..). Your problem translated to solving it in Chef is:

file "/home/user1/file.json" do
  content node['consul']['cluster']['ipaddress'].map { |s| "#{s}:8300" }.to_s
end

If you need non-root ownership and read permissions, have a look at the owner and mode options of the file resource.

This code will do what you specified in your own answer. It's a bit strange though, the string you are aiming looks like an array declaration.

a = ['10.211.130.108','10.211.242.203']
a.map! { |s| "\"#{s}:8300\"" }
result = "[#{a.join(',')}]"
puts result
# Output: ["10.211.130.108:8300","10.211.242.203:8300"]

By replacing map with each, I am still not getting the double quotes. Please check at your end.

BrunoF Over a year ago

Sorry about the confusion. It works now. See edited answer which includes a test. Beware that the map! method will modify your original array in-place. If that is undesired, use the "map" method (without the exclamation mark) and store the returned array in another variable.

I have created an answer, can you help with that. I want output to be surrounded with [] also

I was able to get double quotes using the following:

json_nodes = node['cluster']['ipaddress'].map { |s| "\"#{s.to_s}:8300\"" }

Sure, but if you still use the bash resource for that, you're simply using Chef in a completely wrong way. You just shouldn't do it this way, then you don't run into that quoting problem because you don't have to escape the bash command.
