竹子：每个EC2弹性实例有多个代理？

Question

是否可以针对每个EC2弹性实例运行多个Bamboo代理？

我们在构建系统中使用Docker，而且这个过程似乎主要是网络IO绑定。如果我们可以在一台机器上运行多个代理程序，那将会很不错。

通过一台机器上运行多个代理，而不是启动多台机器，我们也不需要担心机器之间的航运码头工人图像作为文物。

更新2014年10月30日：

我试图复制当前的启动脚本并添加一个新的家：

$ 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 

这似乎是弹性版本建立某种隧道和崩溃因为隧道已经在运行：

任何想法的解决方法？

Answer 1

亚马逊实例是历史上坏提供I/O能力（我假设你的意思是网络I/O）兑美元，因为他们往往需要优化更多的CPU和内存密集型工作负载。您可能会发现在同一个节点上的其他进程可能没有帮助。

如果您在托管服务器镜像上安装了Docker镜像，并在镜像安装后采取snapshot to create an AMI，则可以根据需要启动任意数量的使用该AMI的ec2实例。他们将预安装图像。

您还可以使用CloudFormation和/或云初始化重新编译或下载每个EC2实例图像，而不必担心手工泊坞窗左右移动图像。

但是，如果您确实希望在节点上运行多个竹代理程序，您应该也可以长时间运行，因为您为每个代理程序实例设置了bamboo.home参数。

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/

我们（Atlassian的建设工程）已经建立了一套插件在集群（ECS）是联机运行基于数字泊坞代理商，建立一个单一的工作，然后退出。它应该能够完成你所概述的内容。我们最近开源了解决方案。
