# Docker-Compose environment file for the MariaDB serice

# Comment in the needed variables.
# For further information check:
# https://github.com/docker-library/docs/blob/master/mariadb/README.md#environment-variables

# This specifies the password that will be set for the MariaDB root superuser account.
MARIADB_ROOT_PASSWORD_FILE=/run/secrets/rootPw

#Set to a non-empty value, like yes, to allow the container to be started with a blank password for 
# the root user. 
# NOTE: Setting this variable to yes is not recommended unless you really know what you are doing, 
# since this will leave your MariaDB instance completely unprotected, allowing anyone to gain 
# complete superuser access.
#MARIADB_ALLOW_EMPTY_ROOT_PASSWORD=yes

# Set to a non-empty value, like yes, to generate a random initial password for the root user. The 
# generated root password will be printed to stdout (GENERATED ROOT PASSWORD: .....).
#MARIADB_RANDOM_ROOT_PASSWORD=yes

# This is the hostname part of the root user created. By default this is %, however it can be set 
# to any default MariaDB allowed hostname component. Setting this to localhost will prevent any 
# root user being accessible except via the unix socket.
#MARIADB_ROOT_HOST=

# Set MARIADB_MYSQL_LOCALHOST_USER to a non-empty value to create the mysql@locahost database user. 
# This user is especially useful for a variety of health checks and backup scripts.
# The mysql@localhost user gets USAGE privileges by default. If more access is required, additional 
# global privileges in the form of a comma separated list can be provided. If you are sharing a 
# volume containing MariaDB's unix socket (/var/run/mysqld by default), privileges beyond USAGE can 
# result in confidentiality, integrity and availability risks, so use a minimal set. See the example 
# below on using Mariabackup. The healthcheck.sh script also documents the required privileges for 
# each health check test.
#MARIADB_MYSQL_LOCALHOST_USER=


# This variable allows you to specify the name of a database to be created on image startup.
MARIADB_DATABASE=eaMain

# These are used in conjunction to create a new user and to set that user's password. Both user and 
# password variables are required for a user to be created. This user will be granted all access 
# (corresponding to GRANT ALL) to the MARIADB_DATABASE database.
# Do note that there is no need to use this mechanism to create the root superuser, that user gets 
# created by default with the password specified by the MARIADB_ROOT_PASSWORD variable.
MARIADB_USER_FILE=/run/secrets/eaBackendUser
MARIADB_PASSWORD_FILE=/run/secrets/eaBackendPw

# By default, the entrypoint script automatically loads the timezone data needed for the 
# CONVERT_TZ() function. If it is not needed, any non-empty value disables timezone loading.
#MARIADB_INITDB_SKIP_TZINFO=yes

# Set MARIADB_AUTO_UPGRADE to a non-empty value to have the entrypoint check whether 
# mysql_upgrade/mariadb-upgrade needs to run, and if so, run the upgrade before starting the 
# MariaDB server.
# Before the upgrade, a backup of the system database is created in the top of the datadir with the 
# name system_mysql_backup_*.sql.zst. This backup process can be disabled with by setting 
# MARIADB_DISABLE_UPGRADE_BACKUP to a non-empty value.
#MARIADB_AUTO_UPGRADE=yes
#MARIADB_DISABLE_UPGRADE_BACKUP=yes
