To expose just one port  this is what you need to do   docker run -p  lt host port gt   lt container port gt    To expose multiple ports  simply provide multiple -p arguments   docker run -p  lt host port1 gt   lt container port1 gt  -p  lt host port2 gt   lt container port2 gt

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

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 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
