kops edit cluster ${NAME}
kops update cluster ${NAME} --yes

Sorry, it's my fault. it only supports 17.03.2 and 17.09.

Hi @Caskia how do you know which versions are supported? I cannot find that information anywhere.
Never mind, found it in the release notes:
Docker: Docker 1.13.1 will be used with kubernetes 1.8 (overrides for 17.03.2 and 17.09 possible).
