AWS Batch Container Error: "no users found"-CodePudding

When triggering a batch job (Fargate Job Queue), the status is going to FAILED with the following error message:

Cannotstartcontainererror: ResourceInitializationError: unable to create new container: mount callback failed on /tmp/containerd-mount3975084381: no users found

Unfortunately I can't find any similar errors online.

For reference, the Dockerfile that I'm building is simply the following:

FROM python:3.8-slim-buster
WORKDIR /app
USER root

COPY requirements.txt requirements.txt
RUN pip3 install -r requirements.txt

COPY . .

CMD [ "python3", "run.py"]

And the contents of run.py are as folows:

print("Python script has run!")

The only other file in the image is requirements.txt, which contains just the line requests.

CodePudding user response：

Fixed my own issue:

The job definition had the user set to ubuntu, which wasn't available in the python:3.8-slim-buster image.

Changing this to root fixed the issue.
