Description

Description
docker cli does not support a method to publish a range of ports using the long form syntax.

Steps to reproduce the issue:

Describe the results you received:

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'.

Describe the results you expected:

PS D:\issue> docker run -p mode=host,target=9900-9999,published=9900-9999,protocol=tcp -d hello-world
<ContainerId>

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.
