Issue

docker-compose file format does not support a method of declaring port ranges in the long form syntax defined here: https://docs.docker.com/compose/compose-file/#long-syntax-1

Steps to Reproduce

docker-compose.yml:

version: '3.4'
services:
  helloWorld:
    image: hello-world
    ports:
      - target: 9900-9999
        published: 9900-9999
        protocol: tcp
        mode: host

command executed:

docker-compose -f ./docker-compose.yml config docker-comopse -f ./docker-compose.yml up -d

Expected Output:

PS D:\issue> docker-compose -f ./docker-compose.yml config
services:
  helloWorld:
    image: hello-world
    ports:
      - target: 9900-9999
        published: 9900-9999
        protocol: tcp
        mode: host
version: '3.4'
PS D:\issue> docker-compose -f ./docker-compose.yml up -d
<ContainerId>

Actual Output:

PS D:\issue> docker-compose -f ./docker-compose.yml config

Docker-Compose Version

D:\issue> docker-compose version
docker-compose version 1.18.0, build 8dd22a96
docker-py version: 2.6.1
CPython version: 2.7.14
OpenSSL version: OpenSSL 1.0.2k  26 Jan 2017

Observations

• docker-compose only accepts a single port in long form syntax.
• docker currently appears to only support a single port in long form syntax. See https://github.com/moby/moby/issues/32551

PS D:\issue> docker run -p mode=host,target=9900-9999,published=9900-9999,protocol=tcp -d hello-world
C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Invalid containerPort: mode=host,target=9900-9999,published=9900-9999,protocol=tcp.
See 'C:\Program Files\Docker\Docker\Resources\bin\docker.exe run --help'.

Impacts

• Customers with needs to define a large range of port bindings must declare each port individually if they need to use the long form syntax. This is burdensome and I would prefer to see parity between the long and short form syntax.

Workaround

• Customers who do not need to use the long form syntax can use the short form syntax to declare a range of ports.
• Customers who must use the long form syntax, to control which protocol is used or to bind the ports on the ingress network when deploying to swarm, need to declare each port individually in their compose files.
