10.6.11
Description
In the official MariaDB container image, the old_mode variable - when set at the command line - behaves inconsistently with a locally-installed version of MariaDB 10.6.11 on the same machine.
In addition, the command-line argument handling is inconsistent for string-valued flags when setting them to the empty string.
Environment:
- Docker client and server: Docker Engine Community, 20.10.21
- Host: Rocky Linux 8.7 on x64
- MariaDB version: 10.6.11, installed via RPM or run inside a Docker container.
docker run --rm -e=MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=1 mariadb:10.6 --old-mode=""

The problem could be conflicting information in an external
|
my.cnf files. You can ignore these by doing:
|
|
|
shell> /usr/bin/mariadb-install-db --defaults-file=~/.my.cnf
|
|
|
You can also try to start the mysqld daemon with:
|
|
|
shell> /usr/sbin/mariadbd --skip-grant-tables --general-log &
|
|
|
and use the command line tool /usr/bin/mariadb
|
to connect to the mysql database and look at the grant tables:
|
|
|
shell> /usr/bin/mysql -u root mysql
|
mysql> show tables;
|
|
|
Try 'mysqld --help' if you have problems with paths. Using
|
--general-log gives you a log in /var/lib/mysql/ that may be helpful.

Despite the message given, no logs are left in /var/lib/mysql/ inside the container.
The behaviour changes when the /var/lib/mysql directory is set as a mount inside the container. The first run fails with the "2300 bytes" error, while the second run with the same volume mounted succeeds. (e.g. docker run --mount=type=volume,source=mariadb-test,destination=/var/lib/mysql --rm -e=MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=1 mariadb:10.6 --old-mode="")
seang, cloned from MDEV-30126. Technically producable out of containers by formulating the arguments to mysql_install_db the same way.
