Pure gold. Thanks for this.

omg!!

Thank you for this

Howdy! Thank you for this wonderful howto. I'm sure I've used this solution in the past, but suddenly it doesn't work. I have two Docker configurations managed with docker-compose. I'm trying to dump and restore one database to the other. The docker-compose.yml settings, etc., are identical:

version: '3'
services:
  # ...
  mongo:                       
    image: mongo               
    volumes:                   
      - db_data:/data/db
  #...  
volumes:
  db_data:

At the moment, this is what happens if I execute the instructions you have shared:

2022-05-13T15:04:08.927+0000	Failed: EOF
2022-05-13T15:04:08.928+0000	0 document(s) restored successfully. 0 document(s) failed to restore.

I've tried all manner of trouble-shooting steps found online, but nothing works (--nsInclude, authentication params, etc.). The best I get is:

2022-05-13T15:24:22.680+0000	error connecting to host: could not connect to server: connection() : auth error: sasl conversation error: unable to authenticate using mechanism "SCRAM-SHA-1": (AuthenticationFailed) Authentication failed.

I know this is an old post, but I would be grateful for any suggestions you might have.
