Question

I am trying the connect mariadb with python using docker-compose:

docker-compose.yml

    version: \'2\'
    services:
      mariadb:
        image: bitna         


        

Answer 1

The problem is not with Database or Python code; Its a raise problem coming from Docker, as database needs some time to load and python (consumer.py) container launches faster than database one.

Possible solutions:

docker healthcheck

waittime in docker

add a delay to the python consumer
