@benschw assuming I wanted to change the bind address to 0.0.0.0 in the mysql docker file itself, could I possibly add RUN sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf to https://github.com/mysql/mysql-docker/blob/mysql-server/5.5/Dockerfile#L11 ? Would that work?

I have error on container build:

build command
docker build -t mysql:c_mysql .
output
Sending build context to Docker daemon 4.096kB Step 1/10 : FROM ubuntu ---> 0458a4468cbc Step 2/10 : RUN dpkg-divert --local --rename --add /sbin/initctl ---> Using cache ---> 1f00c319dccb Step 3/10 : RUN ln -s /bin/true /sbin/initctl ---> Running in 322de55db062 ln: failed to create symbolic link '/sbin/initctl': File exists The command '/bin/sh -c ln -s /bin/true /sbin/initctl' returned a non-zero code: 1

Is this part in Dockerfile with error?
RUN dpkg-divert --local --rename --add /sbin/initctl RUN ln -s /bin/true /sbin/initctl

thx
