Running a mysql image

docker run -it mysql-image / bin / bash

started.
I tried to enter MySQL:

mysql -u root -p

requested the password – Introduced “Root” (I don’t know the other) – Issued an error:

Error 2002 (HY000): CAN't Connect to Local MySQL Serve Through Socket '/ Var / Lib / MySQL / mysql.sock '

Tell me how to go to MySQL container? He himself just began to study Docker.

Do you mysqld does not start by passing bash to start docker run -it mysql-image / bash you Speak Doker Do not perform MYSQLD , and open Bash . Try to start the container (without a Basha), see logs if it works, then try to connect. Also, instead of collecting the image itself, you can use it ready.
