我正在尝试在Amazon EC2中部署Dockerfile和Dockerrun.aws.json.我能够成功创建Docker容器但在此之后,实例崩溃了.我不知道为什么 Docker容器意外退出或如何解决它.

日志:

我一直无法找到继续/传递if for a for,any ideas的技巧？请不要提供显式循环作为解决方案,它应该是一行中的所有内容.

我用continue,pass测试了代码,只有当...

list_num=[1,3]
[("Hola"  if i == 1 else continue)  for i in list_num]

我的试验输出:

[("Hola"  if i == 1 else continue)  for i in list_num]
                                    ^
