ddev delere
Delete the environment and the containers completely.
Any changes you have made to the file system is kept, but the database etc is destroyed.
The --omit-snapshots
argument, if specified, tells DDEV to not keep a dump of
the database content for later. If you want it to dump the database so you can
load it back at a later time, don't use this argument.
Example:
$ ddev delete --omit-snapshot
