Ruby YAML数组

Question

我正在使用来自elasticsearch的以下资源：

elasticsearch_configure 'elasticsearch' do
    configuration ({
        'path.repo' => ["/backups/s3_currently_dev", "/backups/s3_currently", "/backups/s3_daily", "/backups/s3_weekly", "/backups/s3_monthly"]
    })
end

我恰好需要以下输出：

path.repo: ["/backups/s3_currently_dev", "/backups/s3_currently", "/backups/s3_daily", "/backups/s3_weekly", "/backups/s3_monthly"]

但我得到了以下几点：

path.repo:
- "/backups/s3_currently_dev"
- "/backups/s3_currently"
- "/backups/s3_daily"
- "/backups/s3_weekly"
- "/backups/s3_monthly"

这似乎不管用。如何获得所需的输出？

重现：

1- Install Chef.
2- Create a cookbook.
3- Use elasticsearch community cookbook to install elasticsearch and configure with the resource shown.
4- Use kitchen or vagrant to create.

您可以使用YAML.load解析现有输出，如下所示：

require 'yaml'
=> true

config = 'path.repo:
 - "/backups/s3_currently_dev"
 - "/backups/s3_currently"
 - "/backups/s3_daily"
 - "/backups/s3_weekly"
 - "/backups/s3_monthly"'
=> "path.repo:\n- \"/backups/s3_currently_dev\"\n- \"/backups/s3_currently\"\n- \"/backups/s3_daily\"\n- \"/backups/s3_weekly\"\n- \"/backups/s3_monthly\""

doc = YAML.load config
=> {"path.repo"=>["/backups/s3_currently_dev", "/backups/s3_currently", "/backups/s3_daily", "/backups/s3_weekly", "/backups/s3_monthly"]}

doc["path.repo"]
=> ["/backups/s3_currently_dev", "/backups/s3_currently", "/backups/s3_daily", "/backups/s3_weekly", "/backups/s3_monthly"]
