docker stop mysql5.7

docker start mysql5.7

docker exec -it mysql5.7 bash

select User, Host from mysql.user;
update mysql.user set host = '%' where user='root';
update mysql.user set host = '%' where user='healthchecker';

DO NOT MOUNT /var/lib/mysq/data directory to docker container as MySQL uses files system of this directory to identify value for lower_case_table_names setting. However, this is not the issue anymore for MySQL 8.0 server as that version of server stores all tables in files with lowercase names.

If /var/lib/mysql mounted to container, file system will be case insensitive (macOS, Windows) and MySQL will set lower_case_table_names=2 which will cause issue because MySQL is actually running on Linux (case sensitive system)**

Correct values for lower_case_table_names should be: lower_case_table_names=2 (macOS and Windows) lower_case_table_names=0 (Unix/Linux)

The mysql server calculates value for lower_case_table_names during initial setup based on File System (/var/lib/mysql/data) See here for more details: https://dev.mysql.com/doc/refman/8.0/en/identifier-case-sensitivity.html

If you need to mount /var/lib/mysql folder for mysql/mysql-server:5.7.19 you need to explicitly set lower_case_table_names=0

MySQL 8.0

docker run --name mysql8.0 -v /Users/eugenmaysyuk/docker/mysql/etc/my.cnf:/etc/my.cnf -p 3306:3306 -d -e MYSQL_ROOT_PASSWORD=master mysql:8.0
