问题:

ddev currently lacks an export-db command (see https://github.com/drud/ddev/issues/767)

How can I export a database?

回答1:

As of ddev v1.4.0 (2018-11-14), there is a ddev export-db command. You can do these things (from ddev export-db -h):

ddev export-db >/tmp/db.sql.gz
ddev export-db --gzip=false >/tmp/db.sql
ddev export-db -f /tmp/db.sql.gz

In addition, don't forget about ddev snapshot, which is a great and quick way to make a quick dump of your db, but it's not as portable as a text-based dump. (See ddev snapshot -h and ddev restore-snapshot -h.)

Original answer with in-container techniques: What I always do is this:

ddev ssh
mkdir /var/www/html/.tarballs
mysqldump db | gzip >/var/www/html/.tarballs/db.sql.gz
# or with explicit authentication
mysqldump -udb -pdb -hdb db | gzip >/var/www/html/.tarballs/db.sql.gz

or for Drupal/drush users:

ddev ssh
drush sql-dump --gzip >.tarballs/my-project-db.sql.gz

That places the dump in the project's .tarballs directory for later use (it's on the host).

However, I'm looking forward to the export-db command when it gets here.

Note also that starting with v1.1.0 you can use the ddev snapshot command to save a copy of a database in the .ddev/db_snapshots directory. It's not a text .sql.gz file, but it's a good saved db.

I think it's very usefull to have the TYPO3 pendant for this, thanks to Outdoorsman for the comment on GitHub Issue above.

I'm coming from the TYPO3 CMS world and also agree this would be a good thing to have. I currently use

ddev ssh and ./vendor/bin/typo3cms database:export | gzip > project_name_db.sql.gz

if the typo3_console extension is installed via composer.

Also You could use Drupal console:

ddev start
ddev ssh    
drupal database:dump
drupal database:restore --file db-2018-07-04-11-31-22.sql

To explain more on @rfay answer, i generally prefer drush cli, however, its based on preference .

ddev start
ddev ssh
drush sql:dump --result-file=../db-export.sql
