竹子：每個EC2彈性實例有多個代理？

Question

是否可以針對每個EC2彈性實例運行多個Bamboo代理？

我們在構建系統中使用Docker，而且這個過程似乎主要是網絡IO綁定。如果我們可以在一臺機器上運行多個代理程序，那將會很不錯。

通過一臺機器上運行多個代理，而不是啓動多臺機器，我們也不需要擔心機器之間的航運碼頭工人圖像作爲文物。

更新2014年10月30日：

我試圖複製當前的啓動腳本並添加一個新的家：

$ cat /opt/bamboo-elastic-agent/bin/bamboo-elastic-agent2 
#!/bin/sh 

bambooAgentBin=$(cd -P -- $(dirname $0) && pwd) 
. $bambooAgentBin/bambooShellFunctions.sh 

echo Starting Elastic Bamboo Agent... 
java -Dbamboo.home=/home/bamboo/bamboo-agent-home-2/ -Dimagefiles.version=3.3-SNAPSHOT -jar $bambooAgentBin/*installer*.jar 2>&1 | tee -a $(getHomeDir)/bamboo-elastic-agent.out 

這似乎是彈性版本建立某種隧道和崩潰因爲隧道已經在運行：

任何想法的解決方法？

亞馬遜實例是歷史上壞提供I/O能力（我假設你的意思是網絡I/O）兌美元，因爲他們往往需要優化更多的CPU和內存密集型工作負載。您可能會發現在同一個節點上的其他進程可能沒有幫助。

如果您在託管服務器鏡像上安裝了Docker鏡像，並在鏡像安裝後採取snapshot to create an AMI，則可以根據需要啓動任意數量的使用該AMI的ec2實例。他們將預安裝圖像。

您還可以使用CloudFormation和/或雲初始化重新編譯或下載每個EC2實例圖像，而不必擔心手工泊塢窗左右移動圖像。

但是，如果您確實希望在節點上運行多個竹代理程序，您應該也可以長時間運行，因爲您爲每個代理程序實例設置了bamboo.home參數。

java -Dbamboo.home=/agent1Home -jar atlassian-bamboo-agent-installer-X.X-SNAPSHOT.jar \ 
     http://bamboo-host-server:8085/agentServer/ 
java -Dbamboo.home=/agent2Home -jar atlassian-bamboo-agent-installer-X.X-SNAPSHOT.jar \ 
     http://bamboo-host-server:8085/agentServer/

我們（Atlassian的建設工程）已經建立了一套插件在集羣（ECS）是聯機運行基於數字泊塢代理商，建立一個單一的工作，然後退出。它應該能夠完成你所概述的內容。我們最近開源瞭解決方案。
