+# Alerta with MongoDB Replica Set Example
+
+Once the mongo containers have started, run an interactive shell in one of the mongoDB containers, like so:
+
+    $ docker exec -ti mongo_db0_1 mongo
+
+To initiate the replicaset, at the `mongo` prompt ">" run:
+
+```
+rs.initiate(
+    {
+        _id: "rs0",
+        version: 1,
+        members: [
+            { _id: 0, host : "db0:27017" },
+            { _id: 1, host : "db1:27017" },
+            { _id: 2, host : "db2:27017" }
