Description
In this paragraph:
we correctly mention that every server must be able to resolve every other server using the FQDN.
However, we do not mention that from every server in the deployment you must be able to contact every MongoDB process in the deployment.
That is, if I have the following servers and MongoDB processes:
- a.example.com: a.example.com:27017
- b.example.com: b.example.com:27018
Then the Automation Agent on a.example.com, must be able to reach the MongoDB process on port 27018 on b.example.com and the Automation Agent on b.example.com must be able to reach the MongoDB process on port 27017 on a.example.com.
This rule holds regardless of what type of MongoDB process is involved (mongos, config server, replica set node, standalone, etc.).
