Backup and restore a mysql database from a running Docker mysql container

mysql-docker.sh

# Backup
docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

# Restore
cat backup.sql | docker exec -i CONTAINER /usr/bin/mysql -u root --password=root DATABASE

Thanks a lot!

mysqldump: Got error: 2002: "Can't connect to local server through socket '/var/run/mysqd/mysqld.socket' (2)" when trying to connect
"Can't connect to local server through socket '/var/run/mysqd/"Can't connect to local server through socket '/var/run/mysqd/mysqld.socket' (2)" when trying to connect

You should get Nobel prize for these two lines of code!

Works perfectly. thank you!

It works, thanks.

It works, for me. Thanks

Thanks!

I've visited this link countless times! Thank you for providing such a helpful sample.

beautiful piece of code

Perfect!

good one @muzzammil194

thanks buddy!

cat backup.sql | docker compose exec -T SERVICE mysql -u root --password=root DATABASE
