Connect to remote MySQL db from docker container

Question

I\'m working to containerize a Django 1.5.x application that connects to a MySQL DB on a separate server via ODBC:

[mysql_default]
database = DB_NAME
driver          


        

Answer 1

I solved this by using the docker host address instead of '127.0.0.1' for queries from within the container:

echo "show databases" | mysql -u DB_USER -pDB_USER_PWD -h 10.0.2.2 --port=3306

Because Docker host ip can vary, this post describes steps to get the right address:
