Here are a few things that we have tried so far in our attempt to use 
windows containers with spinnaker on GCP.

1) We created a docker image on windows of a simple application 
then pushed that image up to our container registry on GCP. The image was 
then grabbed by spinnaker, but every step after that failed. Here is the 
error output we got via Spinnaker:

Failed to pull image "": [rpc error: 
code = 2 desc = unknown blob, rpc error: code = 2 desc = unknown blob]
Error syncing pod, skipping: failed to "StartContainer" for 
"btinterns-168014-hello-node2" with ErrImagePull: "[rpc error: code = 2 
desc = unknown blob, rpc error: code = 2 desc = unknown blob]"
Error syncing pod, skipping: failed to "StartContainer" for 
"btinterns-168014-hello-node2" with ImagePullBackOff: "Back-off pulling 
image \"\ 

2) Since then, we started following this tutorial 
<> and were able 
to seemingly setup the two windows server nodes outlined in the tutorial. 
Problems arose when we started to setup the linux node where the Kubernetes 
control plane is supposed to reside. While we were working on this, we 
discovered the checkbox to enable Kubernetes-alpha features when creating a 
new container cluster on Google Container Engine. We imagine that the 
reason we were getting errors while following the tutorial listed above was 
because that Kubernetes-alpha checkbox was not checked. 

One concern that we have is whether or not we will be able to hook the 
container cluster that we create (which has 1 linux node and 2 windows 
nodes) up with spinnaker. Should we continue deploying spinnaker via the GCP 
or would we be better off & gain more functionality if we deployed it 
ourselves in a new VM on the compute engine?

We are curious to see if anyone has any experience running a 
container on google cloud platform.
