Hello,

I'm having hard time understanding how to do port mapping with PortBindings property of HostConfig.
Adding -p 88:88 to docker run results in following docker condfiguration, how do I do that while utilizing Docker-Powershell?


"PortBindings": {
    "80/tcp": [
        {
            "HostIp": "",
            "HostPort": "88"
        }
    ]
},

This is definitely an area where we need improved support in our cmdlets. We are considering some helper cmdlets that let users more easily create host configurations in the correct format without needing to muddle through the arcane .NET needed to get this object set up. That said, at least there is a way to make it work for now:

$pb = new-object Docker.DotNet.Models.PortBinding
$pb.HostPort = "88"
$hostConfig = new-object Docker.DotNet.Models.HostConfig
$hostConfig.PortBindings = [System.Collections.Generic.Dictionary[string, System.Collections.Generic.iList[Docker.DotNet.Models.PortBinding]]]::new()
$hostConfig.PortBindings.Add("80/tcp",[System.Collections.Generic.List[Docker.DotNet.Models.PortBinding]]::new([Docker.DotNet.Models.PortBinding[]]@($pb)))
$c = New-Container -HostConfiguration $hostConfig microsoft/nanoserver
(Get-ContainerDetail $c).HostConfig.PortBindings

That last command should show the result:

Key    Value
---    -----
80/tcp {Docker.DotNet.Models.PortBinding}

And docker inspect confirms the same (trimmed output):

"PortBindings": {
                "80/tcp": [
                    {
                        "HostIp": "",
                        "HostPort": "88"
                    }
                ]
            },

What am I doing wrong? Port mapping is still not being created

$pb = new-object Docker.DotNet.Models.PortBinding; $pb.HostPort = "8833"
$hostConfig = new-object Docker.DotNet.Models.HostConfig
$hostConfig.PortBindings = [System.Collections.Generic.Dictionary[string, System.Collections.Generic.iList[Docker.DotNet.Models.PortBinding]]]::new()
Run-ContainerImage -HostConfiguration $hostConfig -ImageIdOrName microsoft/iis -Detach

You are setting the PortBindings to a new, empty object, but not adding the $pb into it.  You are missing the line where you call Add:

$hostConfig.PortBindings.Add("80/tcp",[System.Collections.Generic.List[Docker.DotNet.Models.PortBinding]]::new([Docker.DotNet.Models.PortBinding[]]@($pb)))

Still does not work

Import-module docker
$hostConfig = [Docker.DotNet.Models.HostConfig]::new()
$pb = new-object Docker.DotNet.Models.PortBinding
$pb.HostPort = "20003"
$hostConfig.PortBindings = [System.Collections.Generic.Dictionary[string, System.Collections.Generic.iList[Docker.DotNet.Models.PortBinding]]]::new()
$hostConfig.PortBindings.Add("80/tcp",[System.Collections.Generic.List[Docker.DotNet.Models.PortBinding]]::new([Docker.DotNet.Models.PortBinding[]]@($pb)))
Run-ContainerImage -ImageIdOrName "microsoft/iis:latest" -Detach -HostConfiguration $hostConfig -Configuration $config

First one is created by Service Fabric and second one created by script above

If you perform a docker inspect on the second container, do you see the port binding listed in the host config?

I can see it but it's missing bunch of other mapping in other areas (network settings for example) of inspect file. See comparison below
Service Fabric generated one

Have you tried configuring the missing ones on your input objects? Maybe NetworkSettings.Ports and Config.ExposedPorts also need to be configured.

Here is the solution for anybody with the same issue. If you want to port map 8080 on container host to port 80 on container

Import-module docker
$config = [Docker.DotNet.Models.Config]::new()
($config.ExposedPorts  = [System.Collections.Generic.Dictionary[string,object]]::new()).Add("80/tcp", $null)
$hostConfig = [Docker.DotNet.Models.HostConfig]::new()
$pb = new-object Docker.DotNet.Models.PortBinding
$pb.HostPort = "8080"
$hostConfig.PortBindings = [System.Collections.Generic.Dictionary[string, System.Collections.Generic.iList[Docker.DotNet.Models.PortBinding]]]::new()
$hostConfig.PortBindings.Add("80/tcp",[System.Collections.Generic.List[Docker.DotNet.Models.PortBinding]]::new([Docker.DotNet.Models.PortBinding[]]@($pb)))
Run-ContainerImage -ImageIdOrName "microsoft/iis:latest" -Configuration $config -Detach -HostConfiguration $hostConfig -Name $pb.HostPort
