Describe the issue with documentation

https://github.com/apache/airflow/blob/main/CONTRIBUTORS_QUICK_START.rst#setup-and-develop-using-visual-studio-code

I am following the steps on the above page to set up the development environment. however, running the
pyenv install 3.8.5 in Apple M1 chip MacOS Big Sur runs into an error similar to the issue mentioned in the below StackOverflow link

https://stackoverflow.com/questions/65457674/unexpected-output-of-arch-on-osx-using-mac-m1-installing-elastic-beans

How to solve the problem

I am not sure how to solve this issue, but i used higher version of python 3.8.10 that is supported in M1 chip Apple MacOS Big Sur to solve the issue for time being.

Anything else

Further following the steps in this documentation, i got docker container up and running. however, if i try to reset the db, i get error saying

sqlalchemy.exc.OperationalError: (MySQLdb._exceptions.OperationalError) (1130, "Host 'docker-compose_airflow_run_718f404eac1d.docker-compose_defau' is not allowed to connect to this MySQL server")(Background on this error at: http://sqlalche.me/e/13/e3q8)

I am not sure why if i am running into this issue.

Thanks for opening your first issue here! Be sure to follow the issue template!

M1 has some issues indeed. I believe the problem might be that MySQL still does not have ARM image.

But If you managed to fix or at least improve some of those descriptions - feel free!

Sure @potiuk I will add some improvements.

One more thing I forgot to add to this issue:
To get the docker container up, I used the following command
./breeze

Following is the CI image information when running above command:

                               Branch name:            main
                               Docker image:           ghcr.io/apache/airflow/main/ci/python3.8
                               Airflow source version: 2.2.0.dev0
                               Python version:         3.8
                               Backend:                mysql 5.7

However i got the below message when running ./breeze flags

****************************************************************************************************
 Choose backend to run for Airflow

-b, --backend BACKEND
        Backend to use for tests - it determines which database is used.
        One of:

               sqlite mysql postgres mssql

        Default: sqlite

I expected ./breeze to start with sqlite by default but it starts with mysql. Am I missing something?

Some of the parameters (like backend) are "saved" from the previous run and persisted (so that you can run "last used" configuration with just ./breeze.

It is described here https://github.com/apache/airflow/blob/main/BREEZE.rst#choosing-different-breeze-environment-configuration

You can use additional breeze flags to choose your environment. You can specify a Python version to use, and backend (the meta-data database). Thanks to that, with Breeze, you can recreate the same environments as we have in matrix builds in the CI.

For example, you can choose to run Python 3.6 tests with MySQL as backend and in the Docker environment as follows:

./breeze --python 3.6 --backend mysql
The choices you make are persisted in the ./.build/ cache directory so that next time when you use the breeze script, it could use the values that were used previously. This way you do not have to specify them when you run the script. You can delete the .build/ directory in case you want to restore the default settings.
