How to dump and restore my MySQL database on Scalingo

There are two ways to dump a distant database and restore the data in your Scalingo database. The first one involves dumping the data on your local workstation and the second one involves doing the same operations from within a Scalingo one-off container (see application tasks).

Dump and Restore from your local workstation

To dump and restore your database from your local workstation, you need a way to access your database.

A MySQL URL is usually formatted like:


To get the URL of your database, go to the ‘Environment’ part of your dashboard or run the following command:

$ scalingo --app my-app env | grep MYSQL

If your remote database URL is:


Setup the tunnel

$ scalingo --app my-app db-tunnel SCALINGO_MYSQL_URL
scalingo --app my-app db-tunnel SCALINGO_MYSQL_URL
Building tunnel to
You can access your database on ''


The command definition is:

$ mysqldump -u <username> --password=<password> -h <host> -P <port> <db> > dump.sql

Applied to our example:

$ mysqldump -u my-db --password=pass -h -P 10000 my-db > /tmp/dumped_db.sql

As you can see we use the host and port provided by the tunnel, not those of the URL.


The command definition is:

$ mysql -u <username> --password=<password> -h <host> -P <port> <db> < dump.sql

With our example:

$ mysql -u my-db --password=pass -h -P 10000 my-db < /tmp/dumped_db.sql

Dump and Restore from Scalingo one-off container

You can dump and restore your database remotely using the command-line-tool and a one-off container (see application tasks). The advantage of this method is the network. From your workstation you don’t always have a good bandwidth. From our infrastructure, data transfers will be way faster.

Dump & Restore

$ scalingo --app my-app run bash

[00:00] Scalingo ~ $ mysqldump -u user --password=pass -h -P 30000 my-db > /tmp/dumped_db.sql

# Do something with the dump, i.e.e send through FTP or to an external server

[00:00] Scalingo ~ $ mysql -u my-db --password=pass -h -P 30000 my-db < /tmp/dumped_db.sql
[00:00] Scalingo ~ $ exit

After exiting the one-off container, the dump will be lost, you’ve to do something with it in the container.
