The mongodb-atlas-local image stores the replica set information in the /data/db volume. However, each time the container is restarted, it regenerates a replica set config instead of reading the old one and reusing it. This causes a configuration error that prevents the instance from functioning normally.
Steps to reproduce:
- Run a mongodb-atlas-local container (bound to /data/db and /data/configdb)
- Make note of the replica set id via
rs.config()or a similar command - Terminate the docker instance.
- Rerun mongodb-atlas-local
- Get the error
Locally stored replica set configuration does not have a valid entry for the current node; waiting for reconfig or remote heartbeat
The node will be unable to elect a primary as a result and eventually terminate.
The originally generated config set name in this case was “e78f2c1395b4”

Outputs of rs commands on the second run:
rs.status:
MongoServerError[InvalidReplicaSetConfig]: Our replica set config is invalid or we are not a member of it
rs.initiate:
MongoServerError[AlreadyInitialized]: already initialized
rs.config will have the original replica set id.
