How to read parameters from parameters.yml in a service?

I have created a service where I need to read few parameters from parameters.yml, so far I am able to read parameters through container only, I have injected container into my service, I know it's not good practice to inject container instead I should be injecting required services/components,however I am not able to figure out the way to read parameters from parameters.yml without injecting container into service and then reading parameters with the help of container. Can you please guide me for an alternative solution?

EDIT:

I have a long list of parameters, around 12-15, I am storing rate limit options for API in parameters.yml so that they can be easily configured

Thanks.

Since you have a long list a parameters injecting these one by one would be harsh but you can inject array of parameters.

parameters.yml

parameters:
    array_name:
        param1: value1
        param2: value2
        ...

services.yml

services:
    your_service:
        class: Acme\DemoBundle\Class
        arguments: [%array_name%]

your service:

public function __construct(array $parameters)
{
    //access $parameters['param1'], $parameters['param2']
}

You can pass parameter into your service actually. Like this: 

service_name:
    class: <pathToClass>
    arguments:
        - %<parameter-name>%

You can simply pass it in the definition of the service. As example in this xml definition:

    <service id="amce.example_service" class="Acme\DemoBundle\Service\Example">
        <argument type="service" id="templating" />
        <argument>%my_from_parameters%</argument>
    </service>

Hope this help
