Freshly build Docker Image won't start

[aidik]

While running a newly build Docker Image it will fail instantly with following error:

Checking for script in /app/prestart.sh
Running script /app/prestart.sh
Run flask migration upgrades (show current version first)
Usage: flask db current [OPTIONS]
Try 'flask db current --help' for help.

Error: While importing 'app', an ImportError was raised:

This is indeed a Werkzeug 2.1.0 problem, as this package is included in the docker image I can't revert this back as suggested by the StackOverflow answers. I can however just update Flask-Login to be compatible with Werkzeug 2.1.0, let me test this so I can update all dependencies.

@juriansluiman perhaps it could be interesting to integrate dependabot to make these tedious bits more automated in future ?

[obbardc]

Fixed in #25

I was able to fix this by updating Flask-Login to 0.6.2 in requirements.txt

[henriquelino]

I have the same issue, updated flask login but it still happens.

[shsethi]

Worked for me with these versions in requirements.txt

Flask-Migrate==3.1.0
Flask-Login==0.6.2
Flask-Babel==2.0.0
Flask-WTF==1.0.1
python-slugify==6.1.2
pycountry==22.3.5
PyMySQL==1.0.2
sqlalchemy==1.3.24

@juriansluiman can we please merge @obbardc PR (#25) or mine based on @shsethi proposal (#37) if you don't want dependabot. I'm using a mirror of this repo for publishing a docker image in a registry but it's a pain to automate if I have a divergent version.
Thanks
