Build a wiki using docker containers which will be hosted locally. We are using two containers - one for the database (MariaDB) and another for WikiMedia software. 
Prerequisites  
 1. Docker
 2. The file used in the docker-compose command is here - https://shorturl.at/iMAIw

https://github.com/manojjawalkar/Personal-Wiki/blob/main/stack.yml

If you want to run the docker-compose command in detach mode, use the below command
- docker-compose -f stack.yml up -d

Steps:
 1. Run the docker-compose command - This will bring the MediaWiki and MariaDB containers up
 2. Setup the wiki and download the LocalSettings.php file
 3. Put the LocalSettings.php file in the directory where you have placed the stack.yml file. 
 4. Uncomment the  "- ./LocalSettings.php:/var/www/html/LocalSettings.php" line in stack.yml
 5. Re-run the docker-compose command.
