If you wanna remove replication. Remove this flag from “–replicas 3” zero.
But do better, don’t use the HA template. Use the other one. HA is basically replication.
Yes you are. The flags in the yml configs.
I’m quite confused by your purpose here. One moment I think you want to understand how replication works, and now it seems like you don’t want replication. The other time it seems your concern is running all instances of Dgraph on the same host. lol
