Question: I am going through the adding database to elastic beanstalk python documentation but following the steps leads to the following error 2023/05/07 14:06:36.847596 [ERROR] An error occurred during execution of command [app-deploy] - [InstallDependency]. Stop running the command. Error: fail to install dependencies with requirements.txt file with error Command /bin/sh -c /var/app/venv/staging-LQM1lest/bin/pip install -r requirements.txt failed with error exit status 1. Stderr: error: subprocess-exited-with-error × python setup.py egg_info did not run successfully. │ exit code: 1 ╰─> [18 lines of output] /bin/sh: line 1: mysql_config: command not found /bin/sh: line 1: mariadb_config: command not found /bin/sh: line 1: mysql_config: command not found Traceback (most recent call last): File "<string>", line 2, in <module> File "<pip-setuptools-caller>", line 34, in <module> File "/tmp/pip-install-7hpz1pvs/mysqlclient_f18de82744fa43e9b3b8706c3e581791/setup.py", line 15, in <module> metadata, options = get_config() ^^^^^^^^^^^^ File "/tmp/pip-install-7hpz1pvs/mysqlclient_f18de82744fa43e9b3b8706c3e581791/setup_posix.py", line 70, in get_config libs = mysql_config("libs") ^^^^^^^^^^^^^^^^^^^^ File "/tmp/pip-install-7hpz1pvs/mysqlclient_f18de82744fa43e9b3b8706c3e581791/setup_posix.py", line 31, in mysql_config raise OSError("{} not found".format(_mysql_config_path)) OSError: mysql_config not found mysql_config --version mariadb_config --version mysql_config --libs [end of output]  I did some digging and came to the conclusion that mysql or mariadb is not installed to the ec2 instance. So I started browsing the available packages for the Amazon Linux 2023 AMI since my ec2 is running that version and modified my config in .ebextensions folder to look like this: packages: yum: mysql-selinux: [] mariadb105: [] mariadb-connector-c: [] container_commands: 01_migrate: command: "source /var/app/venv/*/bin/activate && python3 manage.py migrate" leader_only: true 02_createsuperuser: command: "source /var/app/venv/*/bin/activate && python3 manage.py createsuperuser --noinput --username aradipatrik2 --email ap@gmail.com" leader_only: true 03_save_data_to_db: command: "source /var/app/venv/*/bin/activate && python3 manage.py save_data_to_db" leader_only: true option_settings: aws:elasticbeanstalk:application:environment: DJANGO_SETTINGS_MODULE: env_info.settings  The packages install successfully but I still get the same exact error. When I ssh into the ec2 device to install mysql or mariadb manually the terminal tells me:  Changes made via SSH WILL BE LOST if the instance is replaced by auto-scaling  So my question is: How can I install mysql or mariadb onto the ec2 instance when deploying the application using elastic beanstalk, so I can have mysqlclient==2.0.3 inside my requirements.txt My requirements.txt asgiref==3.6.0 branca==0.6.0 certifi==2022.12.7 charset-normalizer==3.1.0 Django==4.2.1 folium==0.14.0 idna==3.4 Jinja2==3.1.2 MarkupSafe==2.1.2 numpy==1.24.3 python-dotenv==1.0.0 requests==2.29.0 sqlparse==0.4.4 tzdata==2023.3 urllib3==1.26.15 mysqlclient==2.0.3  edit: Received feedback to install mariadb package with a name ending in -dev or -devel but there's no such package listed at the available packages list for the Amazon Linux 2023 AMI any further pointers would be appreciated!

Answer: After some trial and error I ended up modifying my config file to start with this, which solved my issue packages: yum: mariadb105-devel: []  I found the package completely by chance. If someone know how to discover these for the future please do tell me
