# 使用docker swarm啟動Web服務

Docker Swarm Cluster現在已啟動並正在運行，是時候在Docker Swarm模式下啟動Web服務了。在管理器節點上，運行以下命令以部署Web服務器服務：`docker service create --name webserver -p 8880:80 httpd`

```
docker service create --name webserver -p 8880:80 httpd
```

docker service ls您應該看到以下輸出：

```
sudo docker service ls
ID                  NAME                MODE                REPLICAS            IMAGE               PORTS
dk7qnjx65dnx        webserver           replicated          1/1                 httpd:latest        *:8880->80/tcp

```

接下來，使用以下命令在兩個容器之間擴展Web服務器服務： `docker service scale webserver=2`

```
ebserver scaled to 2
overall progress: 1 out of 2 tasks 
1/2: preparing 
2/2: running

overall progress: 2 out of 2 tasks 
1/2: running   
2/2: running   
verify: Service converged 
```

然後，使用以下命令檢查Web服務器服務的狀態：`docker service ps webserver`您應該看到以下輸出：

```
sudo docker service ps webserver
ID                  NAME                IMAGE               NODE                DESIRED STATE       CURRENT STATE            ERROR               PORTS

```
