MSSQL Init DB Experiments

[pattisdr]

Purpose

Experiments trying to initialize a test mssql db and populate it when we bring up the mssql container on M1.

Known issues:

1. We can't run sql server in docker on M1 because there's no arm64 image - using azure instead
2. While PostgreSQL lets you put an init SQL script in docker-entrypoint-initdb.d, this isn't available for mssql
3. Sqlcmd tool not available inside the arm64 version of edge containers

Changes

Three experiments:

1. First commit tries to create a Dockerfile where we bring up azure and then use sqlcmd to run an initialization script but it looks like I can't use sqlcmd on M1
2. Second commit tries to bring up an additional container just to run a python script to populate database after all the other containers are up when running make integration-env. Errored with Failed to load /var/opt/mssql/mssql.conf ini file with error open /var/opt/mssql/mssql.conf: no such file or directory. Maybe this is permission issues, not sure. This solution isn't ideal because I have to reinstall a lot of things that are in the fidesops container - it would be nice to figure out how to run this python script on the fidesops container -
3. Running the mssql_setup python function which creates a mssql database and populates when we run start_webserver. Works but not great, as we we're combining methods to populate test databases with our core method to bring up fidesops.

Seems to be solved with bringing up docker containers in detached mode including mssql one, then exec-ing into the fidesops to run the python script which creates an mssql_example db and populates, and then we do docker logs for all these containers afterwards.

integration-env: compose-build
	@echo "Bringing up main image and images for integration testing"
	@docker-compose -f docker-compose.yml -f docker-compose.integration-test.yml up -d
	@echo "Waiting 15s for integration containers to be ready..."
	@sleep 15
	@echo "Running additional setup for mssql integration tests"
	@docker exec -it fidesops python tests/integration_tests/mssql_setup.py
	@docker-compose -f docker-compose.yml -f docker-compose.integration-test.yml logs -f -t
