@converge any update? :-)

I had a look this weekend, but there is some issues like
[1] Error: Please install sqlite3 package manually
and it's creating empty folder inside the root folder, I also changed /root folder to /opt in the config files, I'll have time again this weekend, and I'll propose the changes, and ask for your thoughts.

just created a new Docker image, could you test it ? #36

[lerra]

It works for me as long as I hardcode - ${INSTAPY_FOLDER}:${INSTAPY_FOLDER} from the docker compose file to the folders where instapy is, but I guess that was the intent of it and not to have it dynamic ?

Hey, I made a PR last week with a working image and Docker container, did you have some issue using my setup?
