command, you can specify them like this:
```ruby
docker.vm.network :private_network, type: "dhcp", docker_network__internal: true

This will enable the `internal` option for the network when created with `docker network create`.
Where `option` corresponds to the given flag that will be provided to the `docker network create`
command. Similarly, if there is a value you wish to enable when connecting a container
to a given network, you can use the following value in your network config:
```ruby

It should be noted that if you want the container to have a specific IP instead
