Wrong socket path when connecting from within container

[aprat84]

Steps to reproduce:

1. Start a container docker run --name mysql-test -e MYSQL_ROOT_PASSWORD=password -d mysql:8.0-oracle
2. Open a shell inside container docker exec -it mysql-test bash
3. Execute mysql or mysql -u root -p or mysql -u root -ppassword

Throws error ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2).

Real socket path is /var/run/mysqld/mysqld.sock, so I really don't know how it tries to connect to /var/lib/mysql/mysql.sock.

PS: I know I can specify the host, as mysql -h 127.0.0.1 -u root -p, and it works.

Nice catch. The rpm packages are compiled with a different default socket. I'm working on a PR to add socket= to the [client] section of the config file.
