How do I address "OSError: mysql_config not found" error during Elastic Beanstalk deployment?

Question

Problem

I am trying to deploy a very simple app on Elastic Beanstalk with a small database backend. I try to install mysqlclient as part of the process outlined by AWS here. However, when I deploy my app, I get the following error from my Elastic Beanstalk logs as it tries to download the package:

Collecting mysqlclient
  Using cached mysqlclient-2.0.1.tar.gz (87 kB)

Question

The mysqlclient is the AWS recommended driver to connect to a MySQL database in RDS using Flask or Django. How do I get it installed with Elastic Beanstalk?

Context

I’ve tried to implement my architecture with either (1) a database within the Elastic Beanstalk environment or (2) a regularly deployed RDS instance outside the Elastic Beanstalk environment. In this case, we’re going with option (1).

I can’t install mysql-server or other packages using apt-get as suggested here very easily, which is why I hope this isn’t labeled as a duplicate. I don’t have access to the underlying servers. I attempted to using platform hooks and .ebextensions, but I wasn’t able to get that to work. In this post, I’m trying to step back and see if there is another avenue.

Answer 1

For Amazon linux 2 you should be able to install it with yum. Thus, you can have in your .ebextensions a file called, e.g. 01_packages.config with the content:

packages: 
    yum:
        MySQL-python: []

You can add further yum dependencies if you require more.

Just wanted to add what worked for me, which was slightly different from the rest.

Go to this link to see how to set up the folder for your yum packages -> https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/ebextensions.html
(basically make a .ebextensions folder in your projects root)

Then inside that make a 01_packages.config file as suggested by Marcin, and add in this code:

packages: 
  yum:
    python3-devel: []
    mariadb-devel: []

Worked for me uploading to AWS beanstalk and code pipeline via GitHub. Python 3.6 and using flask-mysqldb
