您可以使用下面的代码片段来ssh到EC2实例,并从boto3运行一些命令。
使用boto3来发现实例,fabric来对实例运行命令
这条线索有点老了,但由于我花了一个令人沮丧的下午发现了一个简单的解决方案,我不妨分享一下。
注意这不是对OP问题的严格回答,因为它不使用ssh。但是,boto3的一点是你不必-所以我认为在大多数情况下,这将是实现OP目标的首选方法,因为s/他可以简单地使用他/她现有的boto3配置。
AWS的Run命令内置于botocore中(据我所知,这应该同时适用于boto和boto3),但免责声明:我只使用boto3进行了测试。
对于windows实例powershell命令,您可以使用另一个选项:
