今晚來透過Docker-compose,來建立2個節點的NATS Cluster + 3個節點的NATS Streaming Cluster.
方便後面使用.

參數說明

主要有3個Port4222、8222、6222
4222主要是給Client使用的.
8222是給Monitor的http API用的
6222就是給內部叢集用的.

--cluster_id用來指定cluster id, 預設是test-cluster
--routes用來加入自己到指定的cluster主節點.
--cluster 用來指定自己listen哪個Port, 來處理cluster的請求連入
--store則是有MEMORY/FILE/SQL, 可以來存放raft log, 預設是MEMORY
--dir因為這裡是選擇FILE, 所以透過dir指定log存放位子
--sql_driver如果選擇是SQL, 則這裡有mysql/postgres的驅動選項能選擇

建立成功後, 打開瀏覽器輸入localhost:18222-localhost:18226都要能看到Monitor頁面才是.

有環境後, 之後才好操作!
