Make Database as ReadOnly in Mongo

Question

Is there a way to convert the Mongo database as readonly on the primary node and on all other secondary nodes?

Like in SQL Server, we can alter database like this:

 alter database set readonly

Answer 1

There could be 2 ways to achieve this.

• Connecting to secondary directly instead of primary, not as part of the replica set, then it will behave as read only access.

• Or turn on authentication and create read-only users.
