Errors encountered in solution setup

setup-errors.md

1. First, I ran setup target defined in Makefile as per documentation

   make setup
   

Error logs

 Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "process_linux.go:424: container init caused \"rootfs_linux.go:58: mounting \\\"/home/beebox/d2d-data-challenge-master/app/init_db.py\\\" to rootfs \\\"/var/lib/docker/overlay2/701b781612fb56ef3bc68cffefa7d7deacd10c9e0957cdd667f00ccc69f88eb4/merged\\\" at \\\"/var/lib/docker/overlay2/701b781612fb56ef3bc68cffefa7d7deacd10c9e0957cdd667f00ccc69f88eb4/merged/data/app/init_db.py\\\" caused \\\"not a directory\\\"\"": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

2. Tried getting past this error with the next command

   docker-compose up --force-recreate

3. Attempt to run tests result in error

   make test

4. I made changes in the docker-compose.yml based on the error in Step 1 to the following, did step 1 again and got this error

docker-compose.yml

version: '3.7'
services:
  app:
    build: ./app
    links:
      - telemetrydb
    command:
      - test
    volumes:
      - ./app/Makefile:/data/app/Makefile
      - ./app/challenge/init_db.py:/data/app/init_db.py
      - ./app/run.py:/data/app/run.py
  telemetrydb:
    image: postgres:9.6
    ports:
      - 5432:5432

Error logs

telemetrydb [172.18.0.2] 5432 (postgresql) : Connection refused
DB unavailable, sleeping...
python init_db.py
Traceback (most recent call last):
  File "init_db.py", line 1, in <module>

make: *** [initdb] Error 1
make: *** [Makefile:16: initdb] Error 2

Edit 3: I noticed there were few other parameters that might be off in other files, since I realized that the zip-file shared had some outdated references.
Below are the correct values for sections within each file:

1. volume: section in docker-compose.yml:

      - ./app/Makefile:/app/Makefile
      - ./app/challenge:/app/challenge
      - ./app/run.py:/app/run.py

2. host= property in dwhdb.ini:

host=telemetrydb

3. initdb: and test: commands for app/Makefile:

initdb: waitfordb
	python challenge/init_db.py

test: waitfordb
	pytest challenge

4. References to app/dwhdb.ini in init_db.py, run.py, test_solution.py to be updated to:

'dwhdb.ini'

These changes seem to be a lot and in order to make it simpler I have included zip archive from the latest commit to my solution.

Thanks for your patience and apologies for the mix-up.

Thanks for the revision @r-chauhan!

Looks good.
