You could set it in EB using \n and then convert the '\n' to newlines before you pass it to config.key - something like this (note the single and double quotes in the call to gsub):

single_line_key = ENV.fetch('CLOUDFRONT_KEY')
multi_line_key = single_line_key.gsub('\n', "\n")
config.key = multi_line_key
