Run test

1. Check if images are correct:

Run:

./1.check.sh

2. Setup folders for database tablespaces and scripts

Run:

./2.setup.sh

3. Create containers

Run:

./3.create.sh

4. Run SQL and check results

Run:

./4.test.sh

The expected result would be that the output dir has resuts.txt file with the JSON representation of the transaction run from the sql/test.sql script
