Cannot run mssql 2019 on Openshift

I am trying to run a mssql-server on a company Openshift enviroment, but I am since days a "Permission denied error".

I have already tried to run the container as nonroot container, but it does not help. As well the approach here https://github.com/microsoft/mssql-docker/issues/593 I have tried but I have just memory range up to 4GB... so I dont know if it is enough. However this is the log.

SQL Server 2019 will run as non-root by default.
This container is running as user 1005580000.

And this is my Dockerfile:

FROM mcr.microsoft.com/mssql/server:2019-latest

# Create non-root user and update permissions
#
USER root
RUN useradd -M -s /bin/bash -u 10002 -g 0 mssqltest
RUN mkdir -p -m 770 /var/opt/mssql && chgrp -R 0 /var/opt/mssql

# Grant sql the permissions to connect to ports <1024 as a non-root user
#
RUN setcap 'cap_net_bind_service+ep' /opt/mssql/bin/sqlservr

# Allow dumps from the non-root process
# 
RUN setcap 'cap_sys_ptrace+ep' /opt/mssql/bin/paldumper
RUN setcap 'cap_sys_ptrace+ep' /usr/bin/gdb

# Add an ldconfig file because setcap causes the os to remove LD_LIBRARY_PATH
# and other env variables that control dynamic linking
#
RUN mkdir -p /etc/ld.so.conf.d && touch /etc/ld.so.conf.d/mssql.conf
RUN echo -e "# mssql libs\n/opt/mssql/lib" >> /etc/ld.so.conf.d/mssql.conf
RUN ldconfig

USER mssqltest

Any help would be awesome ^^.
