Bitbucket pipeline import mysql schema

Question

I'm trying to import database schema to mysql service through following statment

mysql -h 127.0.0.1 -u $DB_USERNAME -p$DB_PASSWORD $DB_DATABASE < DB_Schema.sql

and it return mysql: not found . I have even tried the following command

docker exec -i mysql mysql -h 127.0.0.1 -u $DB_USERNAME -p$DB_PASSWORD $DB_DATABASE < DB_Schema.sql

Even though received error + docker exec -i mysql mysql --user=$DB_USERNAME --password=$DB_PASSWORD 5i < DB_Schema.sql Error: No such container: mysql

What would be the best way to use mysql so that I can import a stance of DB into it for testing purpose and how?

Answer 1

You cannot install/update/change you main image in the first step for them to be there in the last step. Make your custom Docker image with all those installations, which will make it faster to run the pipeline and will let you use other tools you need in your pipeline.

Answer 2

I prefer to use the "mysql" client outside Docker and have it reach into the Docker container based on the port mapping set up. Then, conceptually, it is like reading to a "mysqld" server on a separate "server".

LOAD DATA INFILE and INSERT , including use of mysql ... < dump.sql works fine.
