Is there a way to authenticate with private repositories when using the K3D_IMAGE_LOADBALANCER and K3D_IMAGE_TOOLS workaround

[erich23]

Similar to this issue: #1049, I need k3d to work in an environment without public network access so I'm using K3D_IMAGE_LOADBALANCER and K3D_IMAGE_TOOLS environment variables to override k3d images. The problem is our private repositories need authentication to pull images, and despite running docker login successfully, a subsequent k3d cluster create command will fail to pull these images. Here's a sample error:

ERRO[0001] failed Cluster Creation: error creating loadbalancer: runtime failed to create node 'k3d-test-execution-1-serverlb': failed to create container for node 'k3d-test-execution-1-serverlb': docker failed to pull image 'private-artifactory.com/k3d-proxy:5.7.3': docker failed to pull the image 'private-artifactory.com/k3d-proxy:5.7.3': Error response from daemon: unauthorized: The client does not have permission for manifest 

Is there any workaround for this issue? I've been digging online but I'm not seeing anything. It's also a bit confusing with results showing documentation and options for k3d registries.
