Getting random "User not found in file /etc/passwd" error on Cloud Run Job

Question

I'm getting the follow random error, in less than 5% of my job executions, with the same container image:

Application failed to start: resolveUserIdentity("1001"): User not found in file /etc/passwd

My dockerfile:

FROM registry.access.redhat.com/ubi8/ubi-minimal:8.7

RUN microdnf install freetype fontconfig \
    && microdnf clean all
WORKDIR /work/
RUN chown 1001 /work \
    && chmod "g+rwX" /work \
    && chown 1001:root /work
COPY --chown=1001:root target/*.properties target/*.so /work/
COPY --chown=1001:root target/*-runner /work/application


EXPOSE 8080
USER 1001

CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]

Any ideas?

I solved my case editing user 1001 to user 0 in all references in Dockerfile, following a similar fix to an error at GCP Troubleshoot:

https://cloud.google.com/run/docs/troubleshooting?hl=en#error_user_root_is_not_found_in_etcpasswd

FROM registry.access.redhat.com/ubi8/ubi-minimal:8.7

RUN microdnf install freetype fontconfig \
    && microdnf clean all
WORKDIR /work/
RUN chown 0 /work \
    && chmod "g+rwX" /work \
    && chown 0:root /work
COPY --chown=0:root target/*.properties target/*.so /work/
COPY --chown=0:root target/*-runner /work/application


EXPOSE 8080
USER 0

CMD ["./application", "-Dquarkus.http.host=0.0.0.0"]
