Linux container start-up issue in LCOW WS2019: error during CreateProcess: failure in a Windows system call: Unspecified error (0x80004005)

Context: I try to create Linux container from docker file, given below:

Build environment: Windows Server 2019

Enabled LCOW on WS2019 per https://sebastiangogola.com/lcow-linux-containers-on-windows/

Dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-focal
WORKDIR /app

# Copy build
COPY ./bin/ ./bin
COPY ./docker/start.sh ./bin

# This converts line endings from Windows-style to unix-style. If the bash script has windows style endings, it will not run
RUN sed -i 's/\r$//' ./bin/start.sh

# Setup app
EXPOSE 4900
ENTRYPOINT ["./bin/start.sh"]

I get the following exception:

ERROR: for app-testwebapi-linux-x64  Cannot start service app-testwebapi-linux-x64: container 1a10c15c608f98f5aa6997431c9ea2d6dd58e77e03bfff5efcaf164635c47263 encountered an error during CreateProcess: failure in a Windows system call: Unspecified error (0x80004005)

Why this exception? What does it mean?

Issue

start.sh didn't have permission to execute.

Solution #1

grant execute permission on .sh file as below,

RUN chmod +x ./bin/start.sh

Solution #2

Alternative,

Instead of,

COPY ./bin/ ./bin
COPY ./docker/start.sh ./bin

using folder copy of start.sh (when located at ./bin),

COPY ./bin/ ./bin

would help service start-up correctly.

Weird, but, making the change from folder-copy to file-copy is when I started to see the issue.
