docker-mariadb-backup-slave
Setup a mariadb slave server with automysqlbackup
Parameters
SERVER_ID
This is used to customize slave server ID. The default value is 33. You should use an unique ID for each server.
READONLY
When set to 1, the slave server is set as readonly. This is the default. If you set this variable to something different, the database will be read/write.
REPLICATE_DO_DB
This is used to specify a single database to backup. It is generally advised to set this variable to the database name you want to backup.

2019-11-24 10:57:24 0 [Warning] Neither --relay-log nor --relay-log-index were used; so replication may break when this MySQL server acts as a slave and has his hostname changed!! Please use '--log-basename=#' or '--relay-log=mysqld-relay-bin' to avoid this problem.
