Multiple docker containers for mysql or one instance with multiple databases

Question

I have a question regarding best practices using docker containers.

I need one database for each application I develop. Now my question is whether I should use one mysql

Answer 1

Docker is especially suited to the deployment of microservices. The following links discuss two strategies with regard to the use of databases:

1. Database per service
2. Shared database

I personally favour the use of a single database per service and extend that to the deployment of separate instances of a database server. This ensures services are loosely coupled, should one service suffer a DB outage, it won't impact another.
