Version 1.3 of Docker have introduced a long awaited feature which is
docker exec that allowed user to interact with the process inside the container.
docker exec my-lamp cat /var/log/messages
User not only can peek inside the container but actually can enter into container without having additional setup such as
nsenter or others. By spawning a
bash program and stream back terminal to client.
docker exec -it my-lamp /bin/bash
-i will keep the STDIN open thus allowing Bash program to read an input from client.

Sometime we might required to create a clone of existing MySQL table for maintenance purpose or testing an experimental query. We only need 2 query to do this.
CREATE TABLE user_clone LIKE user;
INSERT user_clone SELECT * FROM user;
The first line will create a clone of source table including its index and the second line will copy all data from existing one.
