I'm trying to get a windows (server 2019) based docker container running inside a kubernetes cluster, using the mcr.microsoft.com/windows/servercore:1809 image from here
When deploying the container, I'm getting an error that suggests:
The container operating system does not match the host operating system
Having double checked the operating system in both container and host node (which is a windows server 2019 datacenter system), both show the same:
Microsoft Windows [Version 10.0.17763.437]
The docker container runs ok when run directly on the host system (not within the kubernetes cluster)
Any ideas what's going wrong?
Detail from describe pod below.
