Hi,
i have problem with my mysql after factory reset in docker. Mysql in now broken.
I don’t have any tables in phpmyadmin, and a lot of errors when im trying add user, or add table.
Im not a pro in docker things, but it was working well. 
Im working on BEng Thesis and its really sad :(((

After login on phpmyadmin i dont see any tables and got error:
#1449 - The user specified as a definer (‘mysql.infoschema’@‘localhost’) does not exist - main error
After trying add user
#1064 - Something is wrong in your syntax obok ‘) ORDER BY User ASC, Host ASC’ w linii 1
I posted this at mysql image github and found a solution but it dont working for me:
docker run -it a8a59477268d bash -c mysql_upgrade -uroot -proot
But got error: mysql_upgrade: Got error: 2002: Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2) while connecting to the MySQL server
Upgrade process encountered error and will not continue.
