Description
Hello,
Thank you for an excellent book. I have been reading and following through your examples and through the standardization that Docker provides, the examples still run as expected.
However, in Ch5, when I run ch05-run-nerd-dinner_part-2.ps1 ( after part-1 ), I noticed that while the reverse-proxy service does run, the transcript indicates some errors.
Log:
1 > time="2021-01-16T18:11:08-08:00" level=error msg="Failed to retrieve information of the docker client and server host: error during connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/version: open //./pipe/docker_engine: message readmode pipes not supported In the default daemon configuration on Windows, the docker client must be run elevated to connect.

Here is my Docker host environment :
Powershell : run as an Administrator, with ExecutionPolicy = RemoteSigned, All.
PC: Windows 10, 2004
Docker Desktop: 3.0.4
Docker Engine: 20.10.2
Tried the following :
- Added --isolation hyperv option to Docker run did not work
Based on readmode pipes not supported In the default daemon configuration on Windows StefanScherer/dockerfiles-windows#383
2.Substitute sixeyed/traefik:v1.7.8-windowsservercore-ltsc2019 for a newer Traefix traefik:v2.3.7-windowsservercore-1809 failed with error :
2021/01/16 21:13:12 command traefik error: failed to decode configuration from flags: field not found, node: docker
This tells me that I should look at the Dockerfile for sixeyed/traefik:v1.7.8-windowsservercore-ltsc2019 to find out how the --docker flag should be handled.
Unfortunately sixeyed/traefik is a container, not an image and does not have the Dockerfile available for inspection.
Hopefully, you can provide some guidance to get your example working again.
Thanks,
