I have also tried to run the same container on a windows machine running docker with limited sucess. I have had an operational container and the above error under windows so this seems to be intermittent

Appears to still be a thing in 6.1; I'm seeing the same issue in

FROM microsoft/dotnet:2.1.0-rc1-aspnetcore-runtime-stretch-slim
RUN groupadd -g 999 appuser; useradd -r -u 999 -g appuser appuser

RUN apt-get update -y; \
    apt-get install wget curl gnupg apt-transport-https nano procps ca-certificates -y; \
    curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -; \
    sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-stretch-prod stretch main" > /etc/apt/sources.list.d/microsoft.list'; \
    apt-get update; \
    apt-get install -y powershell; \
USER appuser
ENTRYPOINT [ "pwsh" ]
CMD [ "-File", "initScript.ps1" ]

The initScript.ps1 just unpacks some files before starting a dotnet application.

If I exec -ti into the container I'll get this error sometimes (just after starting pwsh, without entering anything):

$ pwsh

And then if I kill the container and start the exact same image again, everything might work smoothly with no error except Error reading or writing history file '/home/appuser/.local/share/powershell/PSReadLine/ConsoleHost_history.txt': Access to the path '/home/appuser/.local/share/powershell/PSReadLine' is denied. (which doesn't really concern us). Next restart things might still be fine, maybe the one after that as well, and then suddenly a failure. All running the exact same container with the exact same data in it.

In Docker compose environment, the problem occurs only when using the exec subcommand:

docker exec -it cli pwsh
# OR
docker exec -it cli bash
pwsh

But when using attach subcommand, the error does not seems to occur.

docker attach cli
pwsh

This issue happens quite consistently on Ubuntu 16.04/Powershell 6.x, using @mikedbrook's repro in the original post.

Looks like a high-P issue to me.

Does this issue still reproduce to anyone with the latest powershell container images?
I tried mcr.microsoft.com/powershell and mcr.microsoft.com/powershell:lts-ubuntu-16.04 with the @mikedbrook's repro steps, and did not observe the crash. PSReadLine works fine for me in both images.

This issue is closed because it has been marked as requiring author feedback but has not had any activity for 14 days. If you think the issue is still relevant, please reopen and provide your feedback.
