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

This is awesome, thank you!

Anybody figure out this socket issue?
docker exec zabbix-docker-62_zabbix-server_1 /usr/bin/mysqldump -u root --password=secret -S /var/run/mysqd/mysqld.socket zabbix > ~/zabbix.dump

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

mysqld.socket' (2)" when trying to connect

mysql> show variables like 'socket';
+---------------+-----------------------------+
| Variable_name | Value |
+---------------+-----------------------------+
| socket | /var/run/mysqld/mysqld.sock |
+---------------+-----------------------------+
1 row in set (0.01 sec)

mysql> quit
Bye

bash-4.4# ls -l /var/run/mysqld
total 12
-rw-r----- 1 mysql mysql 2 Jan 24 20:28 mysqld.pid
srwxrwxrwx 1 mysql mysql 0 Jan 24 20:28 mysqld.sock
-rw------- 1 mysql mysql 2 Jan 24 20:28 mysqld.sock.lock
srwxrwxrwx 1 mysql mysql 0 Jan 24 20:28 mysqlx.sock

Thanks!

Still works in 2023!
