2022-docker's Issues

copying and mounting scripts at the same time?

Thank you for your valuable videos which help others learn. I am a bit unclear on the following:

• In your Dockerfile you have the following: COPY . /app
• In the docker-compose you have: .:/app

What is the point of copying the directory when we will mount it under /app?

Does this suggest that when deploying it will not use this docker-compose and the code will be copied. Whereas we will use the local mount during development which is mounted using docker-compose. Thanks.

Which version of Python is this tested with?

I like the concept very much but was unable to run it:

Which Python version?

FROM python:latest may not be ideal... ?

Also, why no version numbers in requirements.txt ?

When I tried, after this :

docker build -t channel-api .
docker run -d -p 8080:80 channel-api
```

 I got this :

```
