exec: \"mysql\": executable file not found in $PATH": unknown - mysql

Question

I've created a container based on the mysql:5.7 image. Then I set the password with this
docker run --name mysql -v $(pwd):/src -e MYSQL_ROOT_PASSWORD=password -d mysql:5.7
Then I deployed my modules using docker-compose up -d on my docker-compose.yml file. Apparently, it raised an
exec: \"mysql\": executable file not found in $PATH": unknown
error and my 2 other modules also are having errors that keeps on restarting and point to mysql. I can import Python files in Django shell as well as mysql -u root -p but I cannot use the imports when it can't connect to the database.
Things I did based on my research:
I've set my Windows 10 environment variables to point at
C:\Program Files\MySQL\MySQL Server 8.0\bin where mysql.exe resides. It still didn't work.
mysql-init.txt (REF: https://dev.mysql.com/doc/refman/8.0/en/resetting-permissions.html): This runs the mysql prompt successfully.

Answer 1

Ok, I just got it resolved. Apparently, I forgot to create the DB and migrate the new changes. Here's how I did it.
Removed nginx module. My worker (celery) and websocket_listener modules are okay to keep on restarting. docker rm -f nginx
Ran in detached mode. docker-compose up -d mysql redis
Used bash under mysql container. docker exec -ti mysql bash
Entered credentials (I have initially set them in mysql-init.txt, REF: https://dev.mysql.com/doc/refman/8.0/en/resetting-permissions.html) mysql -u root -p
Created DB. CREATE DATABASE bitpal;
Imported a certain .sql file that was missing in my modules.
Ran bitpal in detached mode. docker-compose up -d bitpal
Used bash under bitpal container. docker exec -ti bitpal bash
Migrations. python manage.py migrate
Used bash under mysql container. docker exec -ti mysql bash
Lastly, ran the sql under bitpal container. mysql -u root -p bitpal < <.sql file>
And it worked.

Answer 2

Here is the best option for the above issue. I did a lot of search for the same issue:
sudo apt-get install --reinstall mariadb-server
sudo apt-get install --reinstall php-mysql
service mysql status
service mysql start
