MySQL service inside docker container not working in macOS Sierra 10.12.6 - mysql

Question

I was forced to reinstall macOS Sierra because I was in the beta program for High Sierra and I get a serious crash so I downgraded the system.
This Dockerfile was working in High Sierra before the sudden crash of the system.
FROM ubuntu:16.04
MAINTAINER XXX version 0.0.1
# Prepare Debian environment
ENV DEBIAN_FRONTEND noninteractive
# we don't need an apt cache in a container
RUN echo "Acquire::http {No-Cache=True;};" > /etc/apt/apt.conf.d/no-cache
# ----------------------------
# Configure supervisor
# ----------------------------
RUN apt-get update > /dev/null 2>&1 && apt-get install -y supervisor > /dev/null 2>&1
RUN mkdir -p /var/log/supervisor
COPY files/supervisord.conf /etc/supervisor/conf.d/supervisord.conf
## Mysql
RUN apt-get install -y mysql-client > /dev/null 2>&1
#RUN debconf-set-selections <<< 'mysql-server mysql-server/root_password password 1234'
#RUN debconf-set-selections <<< 'mysql-server mysql-server/root_password_again password 1234'
RUN echo 'mysql-server mysql-server/root_password password 1234' | debconf-set-selections
RUN echo 'mysql-server mysql-server/root_password_again password 1234' | debconf-set-selections
RUN apt-get -y install mysql-server > /dev/null 2>&1
RUN sed -i -e 's/127.0.0.1/0.0.0.0/g' /etc/mysql/mysql.conf.d/mysqld.cnf
RUN echo "sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE" >> /etc/mysql/mysql.conf.d/mysqld.cnf
RUN usermod -d /var/lib/mysql/ mysql
mys
ADD files/xxx.dump /tmp/xxx.dump
ADD files/mysql_xxx.sql /tmp/mysql_xxx.sql
RUN service mysql start && \
mysql -uroot -p1234 < /tmp/mysql_xxx.sql
RUN rm -rf /var/lib/apt/lists/* /tmp/* /var/tmp/*
RUN apt-get clean
EXPOSE 3306
CMD ["/usr/bin/supervisord"]
Now, reinstalling all things I does not work, it always outputs the same error:
Starting MySQL database server mysqld
...fail!
To add some information, in the step where the Dockerfile stops I am starting the service to dump a database.
My system version macOS Sierra 10.12.6 (16G29) is and my Docker version is 17.06.0-ce-mac19 (18663). Any workaround for this problem?

You should be using the official MySQL Dockerfile as your starting point. You could either just use the MySQL image itself, FROM mysql:5.7 for your Dockerfile or you can copy the Dockerfile and the docker-entrypoint,sh from their Github to "take control" of the MySQL image and not have any dependency on MySQL releases/changes.
I think it is a good idea to use the same OS base for all your Docker containers, you are currently using Ubuntu distro, if you do not mind or are just getting started you may want to have Debian be your OS base. I say this because the Docker images I have looked so far, Cloudbee's Jenkins, .NET Core, ASP.NET COre and MySQL all have a Debian base so I been thinking Debian is the most popular OS base for Docker images though I only have anecdotal evidence of this obviously.
My company prefers CentOS distro, so I took the official MySQL Dockerfile and converted to work with CentOS:7, it was a pain.
