Process running within Docker Container throws OOM error but container doesn't report the error when exited

Inizia riproducendo il caso Windows con il Dockerfile e test.ps1 mostrati nell’issue, quindi ispeziona il Container State con docker inspect e confrontalo con il risultato Linux. Traccia come vengono prodotti lo stato di uscita del container Windows e il campo OOMKilled; il lavoro è completato quando un errore di memoria esaurita a livello di processo in Windows è rappresentato in modo coerente nello stato del container e nel codice di uscita.

Description

I noticed an issue where a process running within a docker container on a Windows VM reported an Out of Memory error according to the logs emitted by docker, however the container itself reported as not exiting due to an OOM error (OOMKilled flag was false when running docker inspect <containerid>) and the exit code reported from the container never matched the expected exit code for an OOM error (Exit code 137). When trying to see if linux had the same behavior when it comes to the process running inside of the container reporting an OOM error, the docker container reported that it was killed due to OOM (OOMKilled flag was true when running docker inspect <containerid> and container reported exit code of 137). I always saw the same behavior in regards to the container reporting that itself wasn't killed due to OOM while the process was reporting OOM errors.

Reproduce

Windows Reproduction Steps:

1. Created simple DockerFile

FROM mcr.microsoft.com/windows/servercore:ltsc2019

COPY test.ps1 .

ENTRYPOINT ["powershell.exe"]

CMD [".\\test.ps1"]

test.ps1 contents

function Consume-Memory {
    $mem = @()

    while ($true) {
        # Allocate 10 MB of memory
        $data = New-Object byte[] (100*1024*1024)
        if (-not $data) {
            throw "Failed to allocate memory. Exiting..."
        }
        $mem += $data
        Write-Host "Allocated chunks: $($mem.Count)"
        Start-Sleep -Seconds 10  # Adjust sleep duration as necessary
    }
}

function Main {
    Consume-Memory
}

Main

2. Built an image using the above file docker build -t <yourtaghere> .
3. Ran a docker container using docker run -m 256 <tag here>
4. Monitored the container memory usage using docker stats
5. When container would eventually exit, I inspected the container using docker inspect <containeridhere>
6. Verified the container did not set the OOMKilled flag as True when the associated docker logs for the container through the path given in the above docker inspect command and process running within the container reported stopping due to an out of memory error.

Linux Reproduction Steps:

These steps are relatively short and simpler than the windows steps.

1. Created simple Dockerfile

FROM public.ecr.aws/amazonlinux/amazonlinux:latest

CMD ["python3", "-c", "foo=' '*1024*1024*512; import time; time.sleep(10)"]

2. Built the image and initiated a container from the image with a limit of 512mb for the container. I used docker build -t <yourtaghere> and docker run -m 512 <tag here>
3. The container would exit almost immediately, emitting exit code 137 which represents an OOM error and the process alongside reported an OutOfMemoryException.

Expected behavior

Docker container running on Windows when encountered with an OutOfMemory error from the process running within the container should report itself as being killed due to OOM error which is the behavior on linux.
