Dumping and restoring MongoDB in a single command

I'm trying to dump an existing MongoDB into a new MongoDB without using dump files at all.

Is there a way to pass data from mongodump into mongorestore using pipes?

something like this:

mongodump --host=0.0.0.0 --port=27017 --db=database_name | mongorestore --host 0.0.0.0 -d database_name --port 27000

Thanks!

Solution

  • I found this solution:

    mongodump -vvvvv --host=0.0.0.0 --port=27017 --db=database_name --archive | mongorestore --archive -vvvvv

    Explained:

    • mongodump a MongoDB util to dump (backup) a database
    • -vvvvv v for verbose, write to stdout the output of the command, more data per v, you can use -v -vv -vvv etc...
    • --host specify the host of the MongoDB you want to dump
    • --host specify the port of the MongoDB you want to dump
    • --archive writes the output to a specified archive file or, if the archive file is unspecified, writes to the standard output (stdout)
    • | takes the output of the command and passes it as input to the next command
    • mongorestore a MongoDB util to restore a database
