# 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/binary_log.cnf
RUN chmod 644 /etc/mysql/conf.d/myisam_perf.cnf

# Remove unnecessary tools
# This removes the following packages:
#   gnupg gnupg-l10n gnupg-utils gpg gpg-agent gpg-wks-client
#   gpg-wks-server gpgsm libsqlite3-0 pinentry-curses
# GPG is probably used by mysql to encrypt logs, but this isn't used in
# our case
RUN apt remove -y --autoremove libsqlite3-0
