Feature: dependsOn functionality for DockerContainer #679
Description
What are you trying to do?
Improve TC-python feature parity with TC-java by enabling container to specify dependsOn, which should work similar to how depends_on in docker-compose does - container B that depends on container A won't be started until container A is in running state.
Why should it be done this way?
Control order/behavior for container startup in multi-container scenarios.
