Change value lower_case_table_names on a running docker container
2 options;


Build the container and ADD or COPY a my.cnf file into place with your desired options.
Bind mount a config file into the container as part of the run command


I think there’s possibly a 3rd but I’m not in the position to test but you can possibly add startup options to the docker run command e.g.

docker run -d {other necessary options} mysql/mysql-server:latest —lower-case-table-names
