It was working before I updated all my dockers in preparation for upgrading to 6.7, now I can't get Rocket.Chat working again. My MongoDB seems to be running just fine, but rocket.chat is giving an error on startup saying MongoError: not master and slaveOk=false I have found some documentation on how to allow reading from the slave, but it is per connection, and RC creates a new connection and I can't figure out how to set that variable for RC to use. I'm getting very close to just installing it on my centos VM and be done with it.

Sure... I see the problem. The echo line they said to in the link that I sent is supposed to be done from the command line, which ends up in the config file like: replication: replSetName: "rs01" here's my full mongod.conf: # mongod.conf # for documentation of all options, see: # http://docs.mongodb.org/manual/reference/configuration-options/ # Where and how to store data. storage: dbPath: /data/db journal: enabled: true # engine: # mmapv1: # wiredTiger: # where to write logging data. systemLog: destination: file logAppend: true path: /var/log/mongodb/mongod.log # network interfaces net: port: 27017 bindIp: 127.0.0.1 # how the process runs processManagement: timeZoneInfo: /usr/share/zoneinfo #security: #operationProfiling: #replication: #sharding: ## Enterprise-Only Options: #auditLog: #snmp: replication: replSetName: "rs01"

I was able to get it working by doing the following: Click on the MongoDB docker icon and select console cp /etc/mongod.conf* /data/db/ ( I renamed it before copying, I think it was called mongod.conf-sample ) exit the MongoDB console go to /mnt/user/appdata/mongodb and edit the sample conf changing the dbPath: to /data/db and the modifications to the conf file noted in https://rocket.chat/docs/installation/manual-installation/mongo-replicas/ rename the file to mongod.conf modify the mongodb docker application Select advanced view Add "-f /data/db/mongod.conf" to the post arguments and restart the mongodb docker go back into the mongodb console, and run mongo and run rs.initiate() then modify the rocket.chat docker container adding the variable: MONGO_OPLOG_URL: mongodb://<SERVER>:27017/local?replSet=rs01 restart rocket.chat and it should be working fine.
