SQLite not working

I tried setting up a local instance of shynet, to test it, but the setup with SQLite did not work. I uncommented the sqlite settings in the .env template file and commented the postgres settings. I tried the command mentioned in the setup guide (docker run --env-file=.env milesmcc/shynet), which threw an error:

Performing startup checks...
Running migrations (setting up DB)...

sqlite3.OperationalError: unable to open database file

The above exception was the direct cause of the following exception:

django.db.utils.OperationalError: unable to open database file
Migrations failed, exiting

It threw the same error without mounting the folder with the database file into the container, and it also failed with mounting the database file directly (./database/db.sqlite3:/var/local/shynet/db/db.sqlite3:rw)

This docker-compose, which should do the same if I’m not mistaken, did also fail with the same error

version: "3.0"
services:
  shynet:
    image: milesmcc/shynet
    container_name: shynet
    restart: unless-stopped
    ports:
      - 8080:8080
    volumes:
      - ./database/db.sqlite3:/var/local/shynet/db/db.sqlite3:rw
    env_file: .env

I have no idea where the problem could be, because I don’t know how django handles databases.

Hey, I had the same issue here, I think it’s because you pull from milesmcc/shynet:latest in the docker hub.

I built the project from the Dockerfile and it worked. 5 months ago this pull request fixed the issue. However, the latest tag in docker hub is 9 months old.

The edge tag seams to be updated more often but it’s not working out of the box for me so the best solution I think is to pull the repo and build from the Dockerfile.

Its working with edge docker image for me now 👍
