So I have 3 ports that should be exposed to the machine's interface. Is it possible to do this with a Docker container?

If you are creating a container from an image and like to expose multiple ports (not publish) you can use the following command:
docker create --name `container name` --expose 7000 --expose 7001 `image name`
Now, when you start this container using the docker start command, the configured ports above will be exposed.
Use this as an example:
docker create --name new_ubuntu -it -p 8080:8080 -p 15672:15672 -p 5432:5432 ubuntu:latest bash
look what you've created(and copy its CONTAINER ID xxxxx):
docker ps -a
now write the miracle maker word(start):
docker start xxxxx
good luck
Only one point to add. you have the option to specify a range of ports to expose in the dockerfile and when running it:
on dockerfile:
EXPOSE 8888-8898
Build image:
docker build -t <image_name>:<version> -f dockerfile .
When running the image:
docker run -it -p 8888-8898:8888-8898 -v C:\x\x\x:/app <image_name>:<version>
