to run this images you just need to set FLASK_APP environtment with -e option when you starting the container. And also you need to make sure the container run on 0.0.0.0 host, you can do it with simply add --host='0.0.0.0' parameter when you about to run a container. Also make sure you forwarded the port of container to the right port with -p option folowed by <dst_port>:5000 i think it's unnecessary but it's good info for you if you want to forward it to specific port.
example for running a simple docker-flask container :
# docker run -it -p 2009:5000 -v $PWD:/usr/src/app -e FLASK_APP=test/test.py wongko/docker-flask flask run --host='0.0.0.0
make sure when you set volume after option -v you using the specific directory for example : /mnt/b2c7efbf-ef52-437d-8ca7-e46ea581cbba/Kuliah/docker-flask because some how i always found error if not give it the "long directory folder". Remember to change the FLASK_APP environtment variable to the directory of your python file. thx
