I am building a SAAS app using kubernetes , and have kong as the app gateway and cockroachdb as my DB. I want to use Kratos as user management service. I do not want to use another to have another managed DB for Kratos at this stage as it will significantly increase the cost. I am keen to know whats the best option now. 1. Can we share the app DB for Kratos too. Will to create issues when we do database migrations? 2. Can we use dockerised postgress or cockrochdb within the cluster? I have read this : https://github.com/ory/kratos/discussions/1810. But keen to know the current recommendations
