Trying to run Podman machine to use with Azure devops build agent - Failed to configure network (networkingMode Nat), falling back to VirtioProxy

[nddipiazza]

I have a local On-Prem Azure Devops instance with Windows build agents

I'd like to utilize Podman from these Windows build agents so that I can utilize Podman inside my Azure Devops pipelines.

I am running a podman machine like so:

podman machine info

host:
    arch: amd64
    currentmachine: podman-machine-default
    defaultmachine: podman-machine-default
    eventsdir: C:\Users\MyServiceAccountHere\.local\share\containers\podman\podman
    machineconfigdir: C:\Users\MyServiceAccountHere\.config\containers\podman\machine\wsl
    machineimagedir: C:\Users\MyServiceAccountHere\.local\share\containers\podman\machine\wsl
    machinestate: Stopped
    numberofmachines: 1
    os: windows
    vmtype: wsl

    os: windows

Here are the Podman commands I'm doing:

podman machine init --user-mode-networking 
podman machine start
podman pull quay.io/podman/hello

Result:

Starting machine "podman-machine-default"
Starting user-mode networking...
wsl: Failed to configure network (networkingMode Nat), falling back to networkingMode VirtioProxy.

This machine is currently configured in rootless mode. If your containers
require root permissions (e.g. ports < 1024), or if you run into compatibility
issues with non-podman clients, you can switch using the following command:

	podman machine set --rootful

API forwarding listening on: npipe:////./pipe/docker_engine

Docker API clients default to this address. You do not need to set DOCKER_HOST.
Machine "podman-machine-default" started successfully

Trying to pull quay.io/podman/hello:latest...
Error: initializing source docker://quay.io/podman/hello:latest: pinging container registry quay.io: Get "https://quay.io/v2/": dial tcp: lookup quay.io: Temporary failure in name resolution
##[error]PowerShell exited with code '1'.

I am not able to query quay.io from my podman container.

Note that the MyServiceAccountHere user that is running the process is not an actually logged in user. They are a service account that runs the Azure Devops agent service process.

How do I allow this Pipeline-like access to work?
