啟動
docker-compose -f zookeeper.yaml up -d
docker-compose -f zookeeper.yaml ps
檢測服務狀態
for i in zk-1 zk-2 zk-3; do
echo "---------------- $i ----------------"
docker exec $i zkServer.sh status
done
檢測埠狀態輸出(imok為正常)
# 內部IP echo ruok | nc 10.10.10.11 2181; echo echo ruok | nc 10.10.10.12 2181; echo echo ruok | nc 10.10.10.13 2181; echo # 外部訪問(替換 127.0.0.1 為宿主機IP) echo ruok | nc 127.0.0.1 2181; echo echo ruok | nc 127.0.0.1 2182; echo echo ruok | nc 127.0.0.1 2183; echo
刪除
docker-compose -f zookeeper.yaml down -v
- docker swarm 方式部署
- 叢集部署 可指定容器執行在哪個宿主機
- 健康策略如果不滿足 退出容器重啟一個
- 無法使用固定IP，無法指定容器名稱
