Hey, sorry you ran into this! The master branch of this repo is in a bit of a weird state at the moment, because it's targeting the master branch of Flask Unchained. Strangely I couldn't get the docker files to work when I tried to install Flask Unchained from master there. I'm working on getting the next version of Flask Unchained released, but I still have some work to do, mainly on the docs. In the meantime, you can checkout commit hash c0b94f3b608d95a349c6fe9b7a99a40c89da42c9 of this repo and that should work:

git checkout c0b94f3b608d95a349c6fe9b7a99a40c89da42c9

I also had to configure the timezone in docker/backend/Dockerfile:

-RUN apk add --no-cache linux-headers make gcc musl-dev libxml2-dev libxslt-dev libffi-dev postgresql postgresql-dev
+RUN apk add --no-cache linux-headers make gcc musl-dev libxml2-dev libxslt-dev libffi-dev postgresql postgresql-dev tzdata
+RUN cp /usr/share/zoneinfo/UTC /etc/localtime
+RUN echo "UTC" > /etc/timezone
