# How to create replicaset for mongodb in docker container
# Before doing step below, please configure your username or password by edit file named 'docker-compose.yml' and './setup/setup.sh'

1.) Compose first with `docker-compose build` or you can use `docker-compose up` for build & run.
2.) When compose done, connect to your primary container by using this `docker-compose exec mongo-rs0-1 mongo -u "root" -p "root"`.
3.) And when mongo shell popup, you need to check is it primary or secondary by `db.isMaster()`.
	a.) You got some returned value, check the object value called by `"ismaster" : true` or `"primary" : "mongo-rs0-1:27017"`.
	b.) When it's in primary cluster, continue to step 4. When it's not, continue to 3b.
	c.) To make your current cluster become primary, execute command below (one by one)
		`cfg = rs.conf();`
		`cfg.members[0].priority = 2;`
		`rs.reconfig(cfg);`
	d.) Now check the cluster state again, is it primary or not?
4.) Create or Add user to your admin database by using this `db.createUser({user: "admin",pwd: "admin",roles: [ { role: "userAdminAnyDatabase", db: "admin" },  { "role" : "clusterAdmin", "db" : "admin" } ]});`
5.) Now you're done :D

NB: All command you have/want to execute without the tick (`)
