Any help what is the different? and what is the error?

Running deploy.py script results in the following error. Any thoughts on why this could happen? I have made some changes in our cluster configuration: updated K8s major version to 1.8, renamed some attribute values, switched to US East 2 zone and downgraded K8s VM size from Standard_E4_v3 to Standard_E2_v3.

./deploy.py -s <SUBSCRIPTION_ID> -n sbdh-jh-v2 -d 1 -D 128

The service account appId and password, and a public ssh key need to be inserted into the cluster json.

Hello,

Can you provide scale-down.py file? for instance if i'd like to decrees the amount of VMs.
dose ARM template support scaling down?

Thanks,
Oshik.

After 10 min of deploy(deploy.py) running i'm getting the following error:

Can you check the git repo and upload config.yaml?
BTW, i found another issues with vmSize. "Standard_D4s_v3" are not supported on ACS. i changed it to "Standard_DS4_v2" and the error disappeared.

Waiting for help.

Thanks!
