Cannot start service traefik: The virtual machine could not be started because a required feature is not installed

Question

I am trying to install Sitecore 10.1.1 with Docker. I am able to successfully pull all docker images with docker-compose pull but when I am trying to do docker-compose up -d, All containers are up successfully except Traefik. I am getting below error for Traefik,

ERROR: for sitecore-xp0_traefik_1  Cannot start service traefik: hcsshim::CreateComputeSystem 308577a1486d02db2b661905e61dd40134cb7cc9467b3ab9c87d1ef69a43ac67: The virtual machine could not be started because a required feature is not installed.

Below are the configurations of my VM,

Windows Edition - Windows Server 2019 Standrad

Version - 1809

OS Build - 17763.1879

Docker Desktop version - 3.3.3

I have HyperV enabled in my machine and Docker desktop is configured to run Windows Container.

Attaching screenshot of the error,

Can someone please help me understand what other feature am I missing here.

Thanks

Answer 1

For me the issue was resolved by changing the isolation process within the docker-compose.yml that the traefik container utilises .

 isolation: ${TRAEFIK_ISOLATION}

to

 isolation: ${ISOLATION}

In my .env file, ${TRAEFIK_ISOLATION} was configured to "hyperv" which was causing issues.

${ISOLATION} on the other hand was set to use the "default" isolation process.
