amazon-ec2 - Bamboo:每个EC2弹性实例有多个代理？

Question

每个EC2 flex 实例是否可以运行多个Bamboo Agent？

我们在构建系统中使用Docker，该过程似乎主要受网络IO约束。如果我们可以在一台计算机上运行多个代理，那就太好了。

通过在一台机器上运行多个代理而不是启动多台机器，我们也不必担心将Docker镜像作为 Artifact 在机器之间进行传送。

2014年10月30日更新:

我尝试复制当前的启动脚本并添加新的主页:

$ 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

似乎 flex 版本建立了某种隧道并崩溃了，因为隧道已经在运行:

有解决办法的想法吗？

Answer 1

我们(Atlassian Build Engineering)创建了一组插件，以在集群(ECS)中运行大量基于Docker的代理，这些代理会联机，构建单个作业然后退出。它应该能够完成您概述的操作。我们最近开源了该解决方案。
