# ----- INSTRUCTION -----
# =======================

# 1. Generate one with: "openssl rand -base64 756 > storage/replica.key"
# 2. Start the container by: "docker compose -f docker-compose.mongors.yaml up -d"
# 3. After the container run the first time (AND ONLY THE FIRST TIME), exec in the container and run these commands:
#   $ docker exec -it mongo bash
#   $ mongosh mongodb://root:diginext@localhost:27017
#   $ rs.initiate({_id: 'rs0', members: [{_id: 0, host: 'localhost:27017'}]})
#   Should receive: "{ ok: 1 }"
# 4. Check the replica set status again:
#   $ rs.status()
# If everything's ok, you are good to go!

# Connection URI: mongodb://root:diginext@localhost:27017/?authSource=admin&replicaSet=rs0
