Mongorestore to a different database

Question

In MongoDB, is it possible to dump a database and restore the content to a different database? For example like this:

mongodump --db db1 --out dumpdir
mongore

Thank you! @Blakes Seven

Adding Docker notes: container names are interchangeable with container ID's

(assumes authenticated, assumes named container=my_db and new_db)

dump:

docker exec -it my_db bash -c "mongodump --uri mongodb://db:password@localhost:27017/my_db --archive --gzip | cat > /tmp/backup.gz"

copy to workstation:

docker cp my_db:/tmp/backup.gz c:\backups\backup.gz

copy into new container(form backups folder):

docker cp .\backup.gz new_db:/tmp

restore from container tmp folder:

docker exec -it new_db bash -c "mongorestore --uri mongodb://db:password@localhost:27017/new_db --nsFrom 'my_db.*' --nsTo 'new_db.*' --gzip --archive=/tmp/backup.gz"
