Amazon Elastic Beanstalk中的Docker部署错误 – Docker容器意外退出
我想通过Elastic Beanstalk部署一个简单的docker容器，但我得到Docker容器意外退出错误。 不知道这里有什么问题。 先谢谢您的帮助。
Dockerrun.aws.json：
{ "AWSEBDockerrunVersion": "1", "Image": { "Name": "janedoe/image", "Update": "true" }, "Ports": [{ "ContainerPort": "10010" }], "Volumes": [{ "HostDirectory": "/home/ec2-user/testdocker", "ContainerDirectory": "/home/ec2-user/testdocker" }], "Logging": "/home/ec2-user/testlogs" } Dockerfile：
FROM centos:centos6 MAINTAINER janedoe
运行回声“testing”EXPOSE 10010

您应该在Dockerfile上使用CMD而不是RUN。
在Dockerfile中执行命令时，必须仔细selectRUN，CMD和ENTRYPOINT（从Docker引用中提取）：
- 跑：
RUN指令将执行当前图像顶部新层的任何命令并提交结果。 生成的提交图像将用于Dockerfile中的下一步。
- CMD：
CMD的主要目的是为正在执行的容器提供默认值 。 这些默认值可以包含可执行文件，也可以省略可执行文件，在这种情况下，您还必须指定一个ENTRYPOINT指令。
- 入口点：
入口点允许你configuration一个将作为可执行文件运行的容器。
您应该深入阅读Docker参考和Docker最佳实践
除此之外，如果您打算使用您在Dockerrun.aws.json中定义的卷，请记住AWS文档中陈述的内容 ：
使用Dockerfile时，请勿在Dockerrun.aws.json文件中指定Image键。 .Elastic Beanstalk将始终构build并使用Dockerfile中描述的映像。
这意味着你的Dockerrun.aws.json将被忽略，所以要小心。
