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

Exactly what I looking for, thanks!

Exactly what I needed. Thank you so much!

Thank you so much. Restore command worked like a charm. Unbelieveable to see that instructions on official Docker image page fail.

this works thank you

good, bro. THANKS.

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

if docker does not add in a group of Linux so it does not execute with full permission
