I have created a MongoDB docker container, with a replica set, using this command:
docker run -d --name mongo -v /data/db:/data/db mongo --replSet name
The container starts running.
I then try to initiate the replica set, using this command:
rs.initiate()
{
"info2" : "no configuration specified. Using a default configuration for the set",
"me" : "fa07bcdd8591:27017",
"info" : "try querying local.system.replset to see current configuration",
"ok" : 0,
"errmsg" : "already initialized",
"code" : 23
}
But it gives the error message "already initialized".
When I check the health of the replica set with the rs.status() command
rs.status()
{
"state" : 10,
"stateStr" : "REMOVED",
"uptime" : 102,
"optime" : {
"ts" : Timestamp(1472680081, 1),
"t" : NumberLong(77)
},
"optimeDate" : ISODate("2016-08-31T21:48:01Z"),
"ok" : 0,
"errmsg" : "Our replica set config is invalid or we are not a member of it",
"code" : 93
}
It says the replica set config is invalid.
