[docker] How can I expose more than 1 port with Docker?

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

Step1

In your Dockerfile, you can use the verb EXPOSE to expose multiple ports.
e.g.

EXPOSE 3000 80 443 22

Step2

You then would like to build an new image based on above Dockerfile.
e.g.

docker build -t foo:tag .

Step3

Then you can use the -p to map host port with the container port, as defined in above EXPOSE of Dockerfile.
e.g.

docker run -p 3001:3000 -p 23:22

In case you would like to expose a range of continuous ports, you can run docker like this:

docker run -it -p 7100-7120:7100-7120/tcp 

if you use docker-compose.ymlfile:

services:
    varnish:
        ports:
            - 80
            - 6081

You can also specify the host/network port as HOST/NETWORK_PORT:CONTAINER_PORT

varnish:
    ports:
        - 81:80
        - 6081:6081
