Documenting issue described in Database Migration tasks/container post in help in Discord.
Basically the issue is that there is not an easy way to run a task automatically, I tried adding the dependencies between services and Garden is still not being able to deploy the task automatically.
I documented two scenarios, each one has their own readme to understand what was the workaround we tried to execute and the issues we faced. Feel free to take a look to both and ask anything to @ShankyJS in Discord!
