Description

Motivation

The command 'docker-compose up' is executed without errors in normal circustancies, but sometimes some of the containers fail later after the docker-compose has finished.

The errors in schedulers are:

The problem is that every container that uses openqa_webui image (webui_webui, webui_websockets, webui_scheduler, webui_livehandler) try to initialize the DB tables. And as all the containers are initialized at the same time surges conflicts.

Acceptance Criteria

  • AC 1: All the containers remain up after execute docker-compose up * AC 2: Expand the docker-compose CI test to include this case
