hualien-tour

the first python flask project using docker-compose

how to use ?

command:

1. docker build -t main .(current working directory:./hulaien-tour) or using docker pull tonyliu666/hualien-flask:latest to pull down from docker hub
2. docker-compose -f docker-compose.yml up --build (if you would like to use detached mode ,you can add -d flag)
3. open your browser and type localhost:8080 and enjoy using it

Write down my learning notes:

1. don't initialize your sql data using python SQLAlchemy(ORM) because of effectiveness ,instead using the original sql command(insert ,create) is much effective
2. The environment variables in docker compose file can be stored as env file to keep secure data
3. docker file CMD vs ENTRYPOINT command . There are some tricks between them .
4. The kind of ports in docker compose file(host port and container port). Each of them has its own timing to be used.Which is better used in the certain scenario is also a key point.
5. The use method of volumes in docker compose file should be handled carefully.Depending on your demands to decide where you store these data(host machine or docker vol.)
