Docker connection mongodb implementation process and code examples

After the container is started

Log in to admin first and create a new user

$ docker exec -it mongo mongo admin
# Create a user named admin with a password of 123456.
>db.createUser({user:"duser",pwd:"test1mongodb23","roles" : [{"role" : "dbAdmin","db" : "cpeducloud2"},
{"role" : "dbOwner","db" : "cpeducloud2"},{"role" : "readWrite","db" : "cpeducloud2"},
{"role" : "userAdmin","db" : "cpeducloud2"}],"mechanisms" : ["SCRAM-SHA-1","SCRAM-SHA-256"]});

 # Try to connect using the user information created above.

> db.auth('duser', 'test1mongodb23')

For example, the library created here is sboot,

After creating the user, log out and log in again with the new user in the new database (sboot)
