  required_providers {
    docker = {
      source  = "kreuzwerker/docker"

          size_bytes = 256 * 1024 * 1024 # 256 MBytes

Panic Output

Expected Behaviour

Docker service with the requested tmpfs mount should have been created

Actual Behaviour

Terraform will finish the plan step, but crash in the apply step. No resources are created.

Steps to Reproduce

1. terraform apply

Important Factoids

A quick glance at the code shows a discrepancy between data types used here:

https://github.com/kreuzwerker/terraform-provider-docker/blob/master/internal/provider/resource_docker_service_structures.go#L835

and here:

https://github.com/kreuzwerker/terraform-provider-docker/blob/master/internal/provider/resource_docker_service_structures.go#L256

I believe the first one should be changed to int as well. I'd like to offer trying to work on a fix for this.
