Steps to test the PR-

1) docker build -t ros-test .

Build command may return error - Failed to load paths: /bin/sh: /opt/app-root/src/.local/share/virtualenvs/src-dqYAXZ28/bin/python: No such file or directory but this can be ignored. Pipenv issue

2) docker run -d --rm --name ros-db --env POSTGRES_PASSWORD=postgres --env POSTGRES_USER=postgres --env POSTGRES_DB=postgres postgres
3) docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' ros-db

3rd command will return the IP of ros-db, use it in next command.

4) docker run --rm --env ROS_DB_HOST=<IP OF ROS-DB> --env ROS_DB_PORT=5432 --name ros-backend -it ros-test
5) docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' ros-backend
6) curl http://<IP Of ROS-backend>:8080/api/status

LGTM 👍
Tested it, works fine!

$ curl http://<IP of ROS-backend>:8080/api/status
{"status": "Application is running!"}
$ curl http://<IP of ROS-backend>:8080/api/systems
{"results":[{"account":"12345","display_name":"machine1-rhel_test123", .... }]}

IP Of ROS-backend: Copied IP from step(5)
