How to setup replica sets to docker containers using custom MongoDB Configuration file - node.js

Question

I Need Your help,
I Created three docker MongoDB containers using a custom sample config file, then I need to implement replica sets to these containers, but I can't implement, and I can't access other containers IP and Port
db.yaml
storage:
dbPath: /data/db
journal:
enabled: true
replication:
replSetName: "my_replicaSet"
net:
bindIp: 127.0.0.1
port: 26017
db1.yaml
storage:
dbPath: /data/db
journal:
enabled: true
replication:
replSetName: "my_replicaSet"
net:
bindIp: 127.0.0.1
port: 28017
db2.yaml
storage:
dbPath: /data/db
journal:
enabled: true
replication:
replSetName: "my_replicaSet"
net:
bindIp: 127.0.0.1
port: 29017
First created three docker containers using below command
Container Name:DB
docker run --name DB -v /home/mahesh/Documents/Trishula/cortana/database:/etc/mongo --net my-mongo-cluster -d mongo --config /etc/mongo/db.yaml
Container Name:DB1
docker run --name DB -v /home/mahesh/Documents/Trishula/cortana/database:/etc/mongo --net my-mongo-cluster -d mongo --config /etc/mongo/db1.yaml
Container Name:DB2
docker run --name DB -v /home/mahesh/Documents/Trishula/cortana/database:/etc/mongo --net my-mongo-cluster -d mongo --config /etc/mongo/db2.yaml
then open a docker container DB shell with mongo --port 26017
initiated Replica sets with rs.initiate()
then add another docker container as a member to that shell by defining rs.add("DB1"), here DB1 is the name of another container, I got the error message like this
my_replicaSet:PRIMARY> rs.add("DB1")
{
"operationTime" : Timestamp(1597812494, 1),
"ok" : 0,
"errmsg" : "Either all host names in a replica set configuration must be localhost references, or none must be; found 1 out of 2",
"code" : 103,
"codeName" : "NewReplicaSetConfigurationIncompatible",
"$clusterTime" : {
"clusterTime" : Timestamp(1597812494, 1),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
}
}
I also tried with given the container port and IP address which is defined in YAML file,
my_replicaSet:PRIMARY> rs.add("127.0.0.1:28017")
{
"operationTime" : Timestamp(1597812984, 1),
"ok" : 0,
"errmsg" : "Quorum check failed because not enough voting nodes responded; required 2 but only the following 1 voting nodes responded: 127.0.0.1:26017; the following nodes did not respond affirmatively: 127.0.0.1:28017 failed with Error connecting to 127.0.0.1:28017 :: caused by :: Connection refused",
"code" : 74,
"codeName" : "NodeNotFound",
"$clusterTime" : {
"clusterTime" : Timestamp(1597812984, 1),
"signature" : {
"hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),
"keyId" : NumberLong(0)
}
}
}
I Had Implemented replica sets with command lines, but I can't implement replica sets with custom MongoDB configuration YAML file with docker MongoDB containers, Please help, I have been working on this for the past one week...
Note: I didn't use docker-compose YAML file...

If you are trying to setup mongodb replicaset locally using docker, refer https://medium.com/#simone.pezzano/quick-docker-and-mongodb-replica-set-on-your-computer-5c2470012a41
