Mysqldump from Docker container

docker exec -i mysql_container mysqldump -uroot -proot --databases database_name --skip-comments > /path/to/my/dump.sql

This will generate a dump.sql file in your host machine. Awesome, eh?
Avoid using --compact on your dump. This will make MySQL check your constraints which will cause troubles when reading your file (damm you MySQL). And don't use --force to fix this scenario: recreate your dump without --compact ¯_(ツ)_/¯

Free O'Reilly books and convenient script to just download them.

Thanks /u/FallenAege/ and /u/ShPavel/ from this Reddit post

How to use:

Take the download.sh file and put it into a directory where you want the files to be saved.
cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.
