Cannot run container with random --user (5.7) #430
Description
This image does not work with a prefilled container in OpenShift. (datadir=/var/lib/mysql2)
Dockerfile for prefilledmysql:example
FROM mysql:5.7.22
#IMPORTANT: MySQL Container runs init in alphanumerical order!
COPY src/*.sql /docker-entrypoint-initdb.d/
ENV MYSQL_ROOT_PASSWORD='somepw'
RUN mkdir -p /var/lib/mysql2 && \
chown -R mysql:mysql /var/lib/mysql2 && \
chmod -R 777 /var/lib/mysql2 && \
sed -i 's|/var/lib/mysql|/var/lib/mysql2|g' /etc/mysql/mysql.conf.d/mysqld.cnf && \
sed -i 's|exec "$@"||g' /entrypoint.sh && \
/entrypoint.sh mysqld && \
chmod -R 777 /var/lib/mysql2/ && \
chown -R mysql:mysql /var/lib/mysql2 && \
find /var/lib/mysql2/ -name "*.cnf" -exec chmod 775 {} \; && \
echo 'exec "$@"' >> /entrypoint.sh
(I also thought about creating a multi stage build - I thought that might drop any problems connected with users)
docker run --user 123456789 prefilledmysql:example

Is there any way to get this to work with a random UID when starting the container?
