Cannot set autoscale when upgrade kubernetes to 1.7.0 version

[chaintng]

I use google container engine and recently upgrade the kubernetes cluster to 1.7.0 However, i got this error when i try to set autoscale to my application

> deis autoscale:set web --min=15 --max=50 --cpu=60 -a MY-APP
Applying autoscale settings for process type web on MY-APP... Error: Unknown Error (400): {"detail":"Invalid version: '1.7+'"}

I had the same problem because some custom deployments of Kubernetes add the '+' to the minor version and the version() function in deis controller takes the complete minor including the '+' so when the HPA resource checks the api version you get the error because it compares with "1.3.0"

So I deployed a custom controller with scheduler's version function modified by me taking only the first element of the minor's string. Is not a good solution since the development side but you can bypass this situation while the people include cases like that in the controller main line.

after upgrade to 1.7.2, it's also work 😕

can confirm this works on 1.7.2:

$ deis autoscale:set web --min=1 --max=3 --cpu=60
Applying autoscale settings for process type web on test-app... done

$ kubectl version

as well as on version 1.7.5:

$ deis autoscale:set web --min=1 --max=3 --cpu=60
