At the moment I have a mongo cluster with two slaves and a master runing on docker
host3:27018 the current version is 3.4.1
My idea was to add one replicaset into my k8s infra, wait for sync, add a second one, wait for sync, add a third one and then kill the old ones.
Not seems that simple, first of all can I do this migrating from
4.0.9 or will I have problems with the replication ?
I made some tests in local doing
docker run -p 27017:27017 mongo:4.0 mongod --replSet rs0 --bind_ip localhost,host1
But I have the folowing error
Failed to set up listener: SocketException: Cannot assign requested address
If you have any idea how to do that, or just let me know if I am going into the good direction :)
