Can we run window server 2019 docker images on window server 2022 host

[sumit84mca]

Hi,

I want to run my docker images which are based on mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019 on a window server running window server 2022.
When I try to create container I get

docker: Error response from daemon: hcsshim::CreateComputeSystem b6d87cd03ef9c3f67b7b69cd56462d00b79c46b90c5cf018c83a8e49450829de: The container operating system does not match the host operating system.

Is it possible to run window server 2019 images on windows server 2022 host.

You can if you use Hyper-V isolation. By default, Docker will use process isolation. You can read more about Windows container version compatibility.

Here's the relevant table for you:

Docker has an --isolation option that let's you configure this.

Note that there are performance considerations when enabling Hyper-V isolation. Read more about Windows container isolation modes.

Hi,
I tried using --isolation=hyperv but then I am getting error
docker: Error response from daemon: hcsshim::CreateComputeSystem 94b67dd038a11af9f330f07e902280bdeba770e0f949fdc6b2c575a6ba02d847: The virtual machine could not be started because a required feature is not installed.

Hyper V is already installed. What else is missing..
