Amazon web services 尝试连接到AWS ECS EC2实例中的容器时，在$PATH中找不到可执行文件

我很难弄清楚如何通过ssh连接到EC2实例中的Docker容器。基本上，我可以进入服务器并使用

docker ps

列出我的容器

但是，我无法在该容器中获得一个shell来运行一些shell脚本，我需要这些shell脚本来运行它

在本地，我只是使用

docker attach [cid] # or 'docker exec -it [cid] bash' to open new shell

。。。但是运行

docker-attach

和

docker-exec-it[cid]bash

时存在明显的问题，我得到了

rpc error: code = 2 desc = "oci runtime error: exec failed: exec: \"bash\": executable file not found in $PATH"

为了提供一些细节，我相信我已经正确设置了ECS。从名为amzn-AMI-2016.03.e-amazon-ecs-optimized的适用社区AMI，我已完成以下设置：

• 适用的ecsInstanceRole和ecsServiceRole
• 正在运行的EC2实例
• 指向该实例的负载平衡器
• ECS中的标记存储库
• 指向ECS存储库的ECS任务定义
• 已分配一个实例插槽的ECS群集，并已通过（我相信）启动脚本成功关联到EC2。这个集群还有一个与我提到的负载平衡器相关联的服务以及相关联的任务定义

我不认为这是我的问题所在（但也许）

也许是我的文件

检查图像/容器中安装了哪个外壳

sudo docker exec -it [cid] echo $SHELL

如果上述命令返回/bin/bash，则docker exec-it[cid]bash应该可以工作

---

否则，您必须使用适当的shell

哦，老兄。。。有时，当我对某件事还不熟悉时，我会花很多时间寻找一些小细节，而这些小细节恰恰是我在更明显的问题上发现的。在这个特殊的例子中，我忽略了我的

docker ps

列表中的“IMAGE”列，假设它一定是我的镜像，而不注意容器ID。唯一运行的容器是

amazon/amazon ecs代理：latest

，所以难怪我在获取外壳时遇到问题
