Dockerfile

FROM mysql:8

COPY config/limit_binary_log.cnf /etc/mysql/conf.d/limit_binary_log.cnf

# By default, COPY uses permissions `-rw-rw-rw-` for the file inside
# the container. But mysql refuses to use config files that are world-
# writable, so we have to change those permissions:
RUN chmod 644 /etc/mysql/conf.d/limit_binary_log.cnf
